cut
cut(1) General Commands Manual cut(1)Name
cut - cut out selected fields of each line of a file
Syntax
cut -clist [file1 file2...]
cut -flist [-dchar] [-s] [file1 file2...]
Description
Use the command to cut out columns from a table or fields from each line of a file. The fields as specified by list can be fixed length,
that is, character positions as on a punched card (-c option), or the length can vary from line to line and be marked with a field delim-
iter character like tab (-f option). The command can be used as a filter. If no files are given, the standard input is used.
Use to make horizontal ``cuts'' (by context) through a file, or to put files together in columns. To reorder columns in a table, use and
Options
list Specifies ranges that must be a comma-separated list of integer field numbers in increasing order. With optional - indicates
ranges as in the -o option of nroff/troff for page ranges; for example, 1,4,7; 1-3,8; -5,10 (short for 1-5,10); or 3- (short
for third through last field).
-clist Specifies character positions to be cut out. For example, -c1-72 would pass the first 72 characters of each line.
-flist Specifies the fields to be cut out. For example, -f1,7 copies the first and seventh field only. Lines with no field delim-
iters are passed through intact (useful for table subheadings), unless -s is specified.
-dchar Uses the specified character as the field delimiter. Default is tab. Space or other characters with special meaning to the
shell must be quoted. The -d option is used only in combination with the -f option, according to XPG3 and SVID2/SVID3.
-s Suppresses lines with no delimiter characters. Unless specified, lines with no delimiters are passed through untouched.
Either the -c or -f option must be specified.
Examples
Mapping of user IDs to names:
cut -d: -f1,5 /etc/passwd
To set name to the current login name for the csh shell:
set name=`who am i | cut -f1 -d" "`
To set name to the current login name for the sh, sh5, and ksh shells:
name=`who am i | cut -f1 -d" "`
Diagnostics
"line too long" A line can have no more than 511 characters or fields.
"bad list for c/f option"
Missing -c or -f option or incorrectly specified list. No error occurs if a line has fewer fields than the list calls
for.
"no fields" The list is empty.
