NAME
cut - select out columns of a file SYNOPSIS
cut [ -b | -c] list [file...] cut -f list [-d delim] [ -s] OPTIONS
-b Cut specified bytes -c Select out specific characters -d Change the column delimiter to delim -f Select out specific fields that are separated by the -i Runs of delimiters count as one -s Suppres lines with no delimiter characters, when used EXAMPLES
cut -f 2 file # Extract field 2 cut -c 1-2,5 file # Extract character columns 1, 2, and 5 cut -c 1-5,7- file # Extract all columns except 6 DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched" Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa- rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man- ual page. SEE ALSO

NAME
cut -- select portions of each line of a file SYNOPSIS
cut -b list [-n] [file ...] cut -c list [file ...] cut -f list [-d delim] [-s] [file ...] DESCRIPTION
The cut utility selects portions of each line (as specified by list) from each file and writes them to the standard output. If no file argu- ments are specified, or a file argument is a single dash ('-'), cut reads from 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 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, over- lapping, 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 the first character of delim 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. -n Do not split multi-byte characters. -s Suppress lines with no field delimiter characters. Unless specified, lines with no delimiters are passed through unmodified. ENVIRONMENT
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). EXAMPLES
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 DIAGNOSTICS
The cut utility exits 0 on success, and >0 if an error occurs. SEE ALSO
paste(1) STANDARDS
The cut utility conforms to IEEE Std 1003.2-1992 (``POSIX.2''). HISTORY
A cut command appeared in AT&T System III UNIX. BUGS
The -c option is a synonym for the -b option, which causes incorrect behaviour in locales that support multibyte characters. When operating on fields (-f option is specified), cut does not recognise multibyte characters, and the delim character is recognised in the middle of multibyte sequences. BSD
