cut(1) cut(1)

default of "C" (see lang(5)) is used instead of LANG. If any internationalization variable contains an invalid

setting, cut behaves as if all internationalization variables are set to "C". See environ(5).

International Code Set Support

cut supports both single- and multi-byte character code sets. International code set characters may be

speciﬁed in the char given to the -d option. cut recognizes the international code set characters accord-

ing to the locale speciﬁed in the LC_CTYPE environment variable.

EXAMPLES

Password ﬁle mapping of user ID to user names:

cut -d : -f 1,5 /etc/passwd

Set environment variable name to current login name:

name=‘who am i | cut -f 1 -d " "‘

Convert ﬁle source containing lines of arbitrary length into two ﬁles where file1 contains the ﬁrst

500 bytes (unless the 500th byte is within a multi-byte character), and file2 contains the remainder of

each line:

cut -b 1-500 -n source > file1

cut -b 500- -n source > file2

DIAGNOSTICS

line too long

Line length must not exceed LINE_MAX characters or ﬁelds, including the new-line char-

acter (see limits(5).

bad list for b/c/f option

Missing -b, -c,or -f option or incorrectly speciﬁed list. No error occurs if a line has

fewer ﬁelds than the list calls for.

no fields list is empty.

WARNINGS

cut does not expand tabs. Pipe text through expand(1) if tab expansion is required.

Backspace characters are treated the same as any other character. To eliminate backspace characters

before processing by cut, use the fold or col command (see fold(1) and col(1)).
