CUT(1) BSD General Commands Manual CUT(1)NAMEcut — select portions of each line of a file
SYNOPSIScut-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 (or the standard input by default), and writes them to the
standard output. 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.
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 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 first 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:
-c list The list specifies character positions.
-d string Use the first character of string as the field delimiter
character instead of the tab character.
-f list The list specifies fields, delimited in the input by a single
tab character. Output fields are separated by a single tab
-s Suppresses lines with no field delimiter characters. Unless
specified, lines with no delimiters are passed through unmod‐
Cut exits 0 on success, 1 if an error occurred.
The cut utility is expected to conform to IEEE Std 1003.2 (“POSIX.2”).
