The cut
utility selects portions of each
line (as specified by list) from each
file and writes them to the standard output. If the
file argument is a single dash (‘-’) or
no file arguments were specified, lines are read 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 and field numbering start from 1.
list is a comma or whitespace separated set
of increasing numbers and/or number ranges. Number ranges consist of a
number, a dash (-
), and a second number and select
the columns or fields from the first number to the second, inclusive.
Numbers or number ranges may be preceded by a dash, which selects all
columns or fields from 1 to the first number. Numbers or number ranges may
be followed by a dash, which selects all columns or fields 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 columns or
fields not present in the input line.
The options are as follows:
-b
list-c
list-d
string-f
list-n
-b
option is used. Characters will only be output 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
The LANG
, LC_ALL
,
and LC_CTYPE
environment variables affect the
execution of cut
if the -n
option is specified. Their effect is described in
environ(7).
The cut
utility exits 0 on success,
and >0 if an error occurs.
The cut
utility conforms to
IEEE Std 1003.2-1992 (“POSIX.2”).
