paste
: Merge lines of files
paste
writes to standard output lines consisting of sequentially
corresponding lines of each given file, separated by a TAB character.
Standard input is used for a file name of ‘-
’ or if no input files
are given.
Synopsis:
paste [option]… [file]…
For example, with:
$ cat num2 1 2 $ cat let3 a b c
Take lines sequentially from each file:
$ paste num2 let3 1 a 2 b c
Duplicate lines from a file:
$ paste num2 let3 num2 1 a 1 2 b 2 c
Intermix lines from stdin:
$ paste - let3 - < num2 1 a 2 b c
Join consecutive lines with a space:
$ seq 4 | paste -d ' ' - - 1 2 3 4
The program accepts the following options. Also see Common options.
-s
’--serial
’
Paste the lines of one file at a time rather than one line from each file. Using the above example data:
$ paste -s num2 let3 1 2 a b c
-d delim-list
’--delimiters=delim-list
’
Consecutively use the characters in delim-list
instead of
TAB to separate merged lines. When delim-list
is
exhausted, start again at its beginning. Using the above example data:
$ paste -d '%_' num2 let3 num2 1%a_1 2%b_2 %c_
-z
’--zero-terminated
’
Delimit items with a zero byte rather than a newline (ASCII LF).
I.e., treat input as items separated by ASCII NUL
and terminate output items with ASCII NUL.
This option can be useful in conjunction with ‘perl -0
’ or
‘find -print0
’ and ‘xargs -0
’ which do the same in order to
reliably handle arbitrary file names (even those containing blanks
or other special characters).
An exit status of zero indicates success, and a nonzero value indicates failure.
