NAME

ccuutt - select portions of each line of a file

SYNOPSIS

ccuutt -bb list [-nn] [file ...]

ccuutt -cc list [file ...]

ccuutt -ff list [-dd delim] [-ss] [file ...]

DESCRIPTION

The ccuutt utility selects portions of each line (as specified by list) from each file and writes them to the standard output. If no file arguments

are specified, or a file argument is a single dash (`-'), ccuutt reads from

the standard input. The items specified by list can be in terms of col-

umn 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, 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:

-bb list

The list specifies byte positions.

-cc list

The list specifies character positions.

-dd delim

Use delim as the field delimiter character instead of the tab character.

-ff list

The list specifies fields, separated in the input by the field

delimiter character (see the -dd option.) Output fields are sepa-

rated by a single occurrence of the field delimiter character.

-nn Do not split multi-byte characters. Characters will only be out-

put 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.

-ss Suppress lines with no field delimiter characters. Unless speci-

fied, lines with no delimiters are passed through unmodified. ENVIRONMENT

The LANG, LCALL and LCCTYPE environment variables affect the execution

of the ccuutt utility. Their effect is described in environ(7). EEXXAAMMPPLLEESS 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 ccuutt utility exits 0 on success, and >0 if an error occurs.
