CUT(1)			  BSD General Commands Manual			CUT(1)

     cutcut out selected portions of each line of a file

     cut -b list [-n] [file ...]
     cut -c list [file ...]
     cut -f list [-d delim] [-s] [file ...]

     The cut utility cuts out selected portions of each line (as specified by
     list) from each file and writes them to the standard output.  If no file
     arguments are specified, or a file argument is a single dash (‘-’), cut
     reads from the standard input.  The items specified by list can be in
     terms of column position or in terms of fields delimited by a special
     character.	 Column numbering starts from 1.

     The list option argument is a comma or whitespace separated set of
     increasing numbers and/or number ranges.  Number ranges consist of a num‐
     ber, a dash (‘-’), and a second number and select the fields or columns
     from the first number to the second, inclusive.  Numbers or number ranges
     may be preceded by a dash, which selects all fields or columns from 1 to
     the last number.  Numbers or number ranges may be followed by a dash,
     which selects all fields or columns from the last number to the end of
     the line.	Numbers and number ranges may be repeated, overlapping, and in
     any order.	 It is not an error to select fields or columns not present in
     the input line.

     The options are as follows:

     -b list
	     The list specifies byte positions.

     -c list
	     The list specifies character positions.

     -d delim
	     Use delim as the field delimiter character instead of the tab

     -f list
	     The list specifies fields, separated in the input by the field
	     delimiter character (see the -d option).  Output fields are sepa‐
	     rated by a single occurrence of the field delimiter character.

     -n	     Do not split multi-byte characters.  Characters will only be out‐
	     put if at least one byte is selected, and, after a prefix of zero
	     or more unselected bytes, the rest of the bytes that form the
	     character are selected.

     -s	     Suppress lines with no field delimiter characters.	 Unless speci‐
	     fied, lines with no delimiters are passed through unmodified.

     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution
     of cut as described in environ(7).

     The cut utility exits 0 on success, and >0 if an error occurs.

     Extract users' login names and shells from the system passwd(5) file as
     “name:shell” pairs:

	   cut -d : -f 1,7 /etc/passwd

     Show the names and login times of the currently logged in users:

	   who | cut -c 1-16,26-38

     colrm(1), paste(1)

     The cut utility conforms to IEEE Std 1003.2-1992 (“POSIX.2”).

     A cut command appeared in AT&T System III UNIX.
