NAME
cut, paste - rearrange columns of data
SYNOPSIS
cut -clist [ file ... ]
cut -flist [ -dchar ] [ file ... ]
paste [ -s ] [ -dchars ] file ...
DESCRIPTION
Cut selects fields from each line of the files (standard input de-
fault). In data base parlance, it projects a relation. The fields can
be fixed length, as on a punched card (option -c), or be marked with a
delimiter character (option -f).
The meanings of the options follow. A list is an increasing sequence
of integers separated by commas, or by - to indicate a range, for exam-
ple
-clist The list specifies character positions.
-flist The list specifies field numbers.
-dchar The character is the delimiter for option -f. Default is tab.
-s Suppress lines with no delimiter characters. Normally such
lines pass through untouched under option -f.
Paste concatenates corresponding lines of the input files and places
the result on the standard output. The file name refers to the stan-
dard input. Lines are glued together with characters taken circularly
from the set chars. The set may contain the special escape sequences
\n (newline), \t (tab), \\ (backslash), and \0 (empty string, not a
null character). The options are
-dchars
The output separator characters. Default is a tab.
-s Paste together lines of one file, treating every line as if it
came from a distinct input.
EXAMPLES
cut -d: -f1,3 /etc/passwd
Print map from login names to userids, see passwd(5).
NAME=`who am i | cut -f1 -d" "`
Set to current login name (subtly different from getuid(1)).
ls | paste - - - -
ls | paste -s '-d\t\n' -
4-column and 2-column file listing

gre(1), awk(1), sed(1), pr(1), column(1)
BUGS
Cut should handle disordered lists under option -f.
In default of file names, paste should read the the standard input.
