cut -- select portions of each line of a file
cut -b list [-n] [file ...]
cut -c list [file ...]
cut -f list [-d string] [-s] [file ...]
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 sec-
ond 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 list specifies byte positions.
-c list list specifies character positions.
-d string Use the first character of string as the field delimiter
character. The default is the <TAB> character.
-f list list specifies fields, separated by the field delimiter char-
acter. The selected fields are output, separated by the
field delimiter character.
-n Do not split multi-byte characters.
-s Suppress lines with no field delimiter characters. Unless
specified, lines with no delimiters are passed through unmod-
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'').
