cut - Cut out selected fields of each line of a file

Synopsis

cut -b list [file ...]

cut -c list [file ...]

cut -f list [-d string] [-s] [file ...]

Description

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.

The 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 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.

Options

-b list

The list specifies byte positions.

-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 character.

-s

Suppresses lines with no field delimiter characters. Unless specified, lines with no delimiters are passed through unmodified.
