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 separated 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 manual page.
