# users=%lu
�
-T implied by -l nn when nn <= 10 or <= 3 with -F. With no FILE, or when
FILE is -, read standard input.
�
A field is a run of whitespace, then non-whitespace characters.
Fields are skipped before chars.
�
A lightweight `finger' program;  print user information.
The utmp file will be %s.
�
A mere - implies -i.  If no COMMAND, print the resulting environment.
�
A mere - implies -l.   If USER not given, assume root.
�
An omitted EXPRESSION defaults to false.  Otherwise,
EXPRESSION is true or false and sets exit status.  It is one of:
�
As a special case, cp makes a backup of SOURCE when the force and backup
options are given and SOURCE and DEST are the same name for an existing,
regular file.
�
BLOCKS and BYTES may be followed by the following multiplicative suffixes:
xM M, c 1, w 2, b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024,
GB 1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y.

Each CONV symbol may be:

�
Beware that many operators need to be escaped or quoted for shells.
Comparisons are arithmetic if both ARGs are numbers, else lexicographical.
Pattern matches return the string matched between $ and $ or null; if
$ and $ are not used, they return the number of characters matched or 0.
�
Both MAJOR and MINOR must be specified when TYPE is b, c, or u, and they
must be omitted when TYPE is p.  If MAJOR or MINOR begins with 0x or 0X,
it is interpreted as hexadecimal; otherwise, if it begins with 0, as octal;
otherwise, as decimal.  TYPE may be:
�
By default, selects -v1 -i1 -l1 -sTAB -w6 -nrn -hn -bt -fn.  CC are
two delimiter characters for separating logical pages, a missing
second character implies :.  Type \\ for \.  STYLE is one of:
�
By default, sparse SOURCE files are detected by a crude heuristic and the
corresponding DEST file is made sparse as well.  That is the behavior
selected by --sparse=auto.  Specify --sparse=always to create a sparse DEST
file whenever the SOURCE file contains a long enough sequence of zero bytes.
Use --sparse=never to inhibit creation of sparse files.

�
Combination settings:
 * [-]LCASE      same as [-]lcase
   cbreak        same as -icanon
   -cbreak       same as icanon
�
Control settings:
   [-]clocal     disable modem control signals
   [-]cread      allow input to be received
 * [-]crtscts    enable RTS/CTS handshaking
   csN           set character size to N bits, N in [5..8]
�
Each FLAG symbol may be:

append    append mode (makes sense only for output)
�
Except for -h and -L, all FILE-related tests dereference symbolic links.
Beware that parentheses need to be escaped (e.g., by backslashes) for shells.
INTEGER may also be -l STRING, which evaluates to the length of STRING.
�
Exit status is 0 if EXPRESSION is neither null nor 0, 1 if EXPRESSION is null
or 0, 2 if EXPRESSION is syntactically invalid, and 3 if an error occurred.
�
Exit status is 0 if OK, 1 if minor problems, 2 if serious trouble.
�
FORMAT controls the output as in C printf.  Interpreted sequences are:

\"      double quote
  \NNN    character with octal value NNN (1 to 3 digits)
  \\      backslash
�
Handle the tty line connected to standard input.  Without arguments,
prints baud rate, line discipline, and deviations from stty sane.  In
settings, CHAR is taken literally, or coded as in ^c, 0x37, 0177 or
127; special values ^- or undef used to disable special characters.
�
If -e is in effect, the following sequences are recognized:

\0NNN   the character whose ASCII code is NNN (octal)
  \\     backslash
  \a     alert (BEL)
  \b     backspace
�
If FILE is -, shred standard output.

Delete FILE(s) if --remove (-u) is specified.  The default is not to remove
the files because it is common to operate on device files like /dev/hda,
and those files usually should not be removed.  When operating on regular
files, most people use the --remove option.

�
If FILE is not specified, use %s.  %s as FILE is common.
If ARG1 ARG2 given, -m presumed: `am i' or `mom likes' are usual.
�
If FILE is specified, read it to determine which colors to use for which
file types and extensions.  Otherwise, a precompiled database is used.
For details on the format of these files, run `dircolors --print-database'.
�
If FIRST or INCREMENT is omitted, it defaults to 1.  That is, an
omitted INCREMENT defaults to 1 even when LAST is smaller than FIRST.
FIRST, INCREMENT, and LAST are interpreted as floating point values.
INCREMENT is usually positive if FIRST is smaller than LAST, and
INCREMENT is usually negative if FIRST is greater than LAST.
When given, the FORMAT argument must contain exactly one of
the printf-style, floating point output formats %e, %f, %g
�
If a FILE is -, copy again to standard output.
�
If first and second call formats both apply, the second format is assumed
if the last operand begins with + or (if there are 2 operands) a digit.
An OFFSET operand means -j OFFSET.  LABEL is the pseudo-address
at first byte printed, incremented when dump is progressing.
For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal;
suffixes may be . for octal and b for multiply by 512.

TYPE is made up of one or more of these specifications:

a          named character
  c          ASCII character or backslash escape
�
If no command is given, run ``${SHELL} -i'' (default: /bin/sh).
�
If the first character of N (the number of bytes or lines) is a `+',
print beginning with the Nth item from the start of each file, otherwise,
print the last N items in the file.  N may have a multiplier suffix:
b 512, k 1024, m 1024*1024.

�
Input settings:
   [-]brkint     breaks cause an interrupt signal
   [-]icrnl      translate carriage return to newline
   [-]ignbrk     ignore break characters
   [-]igncr      ignore carriage return
�
Local settings:
   [-]crterase   echo erase characters as backspace-space-backspace
 * crtkill       kill all line by obeying the echoprt and echoe settings
 * -crtkill      kill all line by obeying the echoctl and echok settings
�
N may have a multiplier suffix: b 512, k 1024, m 1024*1024.
�
Note that if you use rm to remove a file, it is usually possible to recover
the contents of that file.  If you want more assurance that the contents are
truly unrecoverable, consider using shred.
�
Optional - before SETTING indicates negation.  An * marks non-POSIX
settings.  The underlying system defines which settings are available.
�
Output settings:
 * bsN           backspace delay style, N in [0..1]
 * crN           carriage return delay style, N in [0..3]
 * ffN           form feed delay style, N in [0..1]
 * nlN           newline delay style, N in [0..1]
�
Owner is unchanged if missing.  Group is unchanged if missing, but changed
to login group if implied by a `:' following a symbolic OWNER.
OWNER and GROUP may be numeric as well as symbolic.
�
POS is F[.C][OPTS], where F is the field number and C the character position
in the field.  OPTS is one or more single-letter ordering options, which
override global ordering options for that key.  If no key is given, use the
entire line as the key.

SIZE may be followed by the following multiplicative suffixes:
�
Print the value of EXPRESSION to standard output.  A blank line below
separates increasing precedence groups.  EXPRESSION may be:

ARG1 | ARG2       ARG1 if it is neither null nor 0, otherwise ARG2

ARG1 & ARG2       ARG1 if neither argument is null or 0, otherwise 0
�
RADIX is d for decimal, o for octal, x for hexadecimal or n for none.
BYTES is hexadecimal with 0x or 0X prefix, it is multiplied by 512
with b suffix, by 1024 with k and by 1048576 with m.  Adding a z suffix to
any type adds a display of printable characters to the end of each line
of output.  �
Read standard input if FILE is -.  Each PATTERN may be:
�
Report bugs to <%s>.
�
SETs are specified as strings of characters.  Most represent themselves.
Interpreted sequences are:

\NNN            character with octal value NNN (1 to 3 octal digits)
  \\              backslash
  \a              audible BEL
  \b              backspace
  \f              form feed
  \n              new line
  \r              return
  \t              horizontal tab
�
SIGNAL may be a signal name like `HUP', or a signal number like `1',
or an exit status of a process terminated by a signal.
PID is an integer; if negative it identifies a process group.
�
SIZE is a number.  For TYPE in doux, SIZE may also be C for
sizeof(char), S for sizeof(short), I for sizeof(int) or L for
sizeof(long).  If TYPE is f, SIZE may also be F for sizeof(float), D
for sizeof(double) or L for sizeof(long double).
�
SIZE may be (or may be an integer optionally followed by) one of following:
kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.
�
SIZE may have a multiplier suffix: b for 512, k for 1K, m for 1 Meg.
�
Special characters:
 * dsusp CHAR    CHAR will send a terminal stop signal once input flushed
   eof CHAR      CHAR will send an end of file (terminate the input)
   eol CHAR      CHAR will end the line
�
Special settings:
  N             set the input and output speeds to N bauds
 * cols N        tell the kernel that the terminal has N columns
 * columns N     same as cols N
�
The backup suffix is `~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control method may be selected via the --backup option or through
the VERSION_CONTROL environment variable.  Here are the values:

�
The sums are computed as described in %s.  When checking, the input
should be a former output of this program.  The default mode is to print
a line with checksum, a character indicating type (`*' for binary, ` ' for
text), and name for each FILE.
�
To remove a file whose name starts with a `-', for example `-foo',
use one of these commands:
  %s -- -foo

%s ./-foo
�
Traditional format specifications may be intermixed; they accumulate:
  -a   same as -t a,  select named characters
  -b   same as -t o1, select octal bytes
  -c   same as -t c,  select ASCII characters or backslash escapes
  -d   same as -t u2, select unsigned decimal 2-byte units
�
Translation occurs if -d is not given and both SET1 and SET2 appear.
-t may be used only when translating.  SET2 is extended to length of
SET1 by repeating its last character as necessary.  �
Unless -t CHAR is given, leading blanks separate fields and are ignored,
else fields are separated by CHAR.  Any FIELD is a field number counted
from 1.  FORMAT is one or more comma or blank separated specifications,
each being `FILENUM.FIELD' or `0'.  Default FORMAT outputs the join field,
the remaining fields from FILE1, the remaining fields from FILE2, all
separated by CHAR.

Important: FILE1 and FILE2 must be sorted on the join fields.
�
Use one, and only one of -b, -c or -f.  Each LIST is made up of one
range, or many ranges separated by commas.  Selected input is written
in the same order that it is read, and is written exactly once.
Each range is one of:

N     N'th byte, character or field, counted from 1
  N-    from N'th byte, character or field, to end of line
  N-M   from N'th to M'th (included) byte, character or field
  -M    from first to M'th (included) byte, character or field

With no FILE, or when FILE is -, read standard input.
�
With no FILE or if FILE is -, read Standard Input.  `-F /' by default.
�
With no FILE, or when FILE is -, read standard input.
�
With no options, produce three-column output.  Column one contains
lines unique to FILE1, column two contains lines unique to FILE2,
and column three contains lines common to both files.
�
Without any OPTION, print some useful set of identified information.
�
Write an unambiguous representation, octal bytes by default,
of FILE to standard output.  With more than one FILE argument,
concatenate them in the listed order to form the input.
With no FILE, or when FILE is -, read standard input.

�                    separate columns by STRING,
                    without -S: Default separator <TAB> with -J and <space>
                    otherwise (same as -S" "), no effect on column options
  -t, --omit-header omit page headers and trailers
�      --backup[=CONTROL]      make a backup of each existing destination file
  -b                          like --backup but does not accept an argument
  -d, -F, --directory         allow the superuser to attempt to hard link
                                directories (note: will probably fail due to
                                system restrictions, even for the superuser)
  -f, --force                 remove existing destination files
�      --backup[=CONTROL] make a backup of each existing destination file
  -b                  like --backup but does not accept an argument
  -c                  (ignored)
  -d, --directory     treat all arguments as directory names; create all
                        components of the specified directories
�      --block-size=SIZE      use SIZE-byte blocks
  -B, --ignore-backups       do not list implied entries ending with ~
  -c                         with -lt: sort by, and show, ctime (time of last
                               modification of file status information)
                               with -l: show ctime and sort by name
                               otherwise: sort by ctime
�      --complement        complement the set of selected bytes, characters
                            or fields.
�      --from=CURRENT_OWNER:CURRENT_GROUP
                         change the owner and/or group of each file only if
                         its current owner and/or group match those specified
                         here.  Either may be omitted, in which case a match
                         is not required for the omitted attribute.

�The following options modify how a hierarchy is traversed when the -R
option is also specified.  If more than one is specified, only the final
one takes effect.

-H                     if a command line argument is a symbolic link
                         to a directory, traverse it

  -P                     do not traverse any symbolic links (default)

�The strings compared were %s and %s.�This default behavior is not desirable when you really want to
track the actual name of the file, not the file descriptor (e.g., log
rotation).  Use --follow=name in that case.  That causes tail to track the
named file by reopening it periodically to see if it has been removed and
recreated by some other program.
