paste(1)


paste -- merge same lines of several files or subsequent lines of one file

Synopsis

paste file1 file2 . . .

paste -dlist file1 file2 . . .

paste -s [-dlist] file1 . . .

Description

In the first two forms, paste concatenates corresponding lines of the given input files file1, file2, and so on. It treats each file as a column or columns of a table and pastes them together horizontally (parallel merging). If you will, it is the counterpart of cat(1) which concatenates vertically, that is, one file after the other. In the last form above, paste replaces the function of an older command with the same name by combining subsequent lines of the input file (serial merging). If more than one file is specified with the -s option, paste(1) concatenates the merged files one below the other. In all cases, lines are glued together with the tab character, or with characters from an optionally specified list. Output is to the standard output, so it can be used as the start of a pipe, or as a filter, if - is used in place of a file name. paste processes supplementary code set characters in files, and recognizes supplementary code set characters in the list given to the -d option (see below) according to the locale specified in the LC_CTYPE environment variable [see LANG on environ(5)).

A ``-'' may be used in place of any file name to read a line from the standard input. (There is no prompting.)

The meanings of the options are:


-d
Without this option, the new-line characters of each but the last file (or last line in case of the -s option) are replaced by a tab character. This option allows replacing the tab character by one or more alternate characters (see below).

list
One or more characters immediately following -d replace the default tab as the line concatenation character. The list is used sequentially and circularly: first, the first element on the list is used to concatenate the lines, then the next, and so on; when all elements have been used, the list is reused starting from the first element. In parallel merging (that is, no -s option), the lines from the last file are always terminated with a new-line character, not from the list. The list may contain the special escape sequences: \n (new-line), \t (tab), \\ (backslash), and \0 (empty string, not a null character). Quoting may be necessary, if characters have special meaning to the shell (for example, to get one backslash, use -d\\\\). list may contain supplementary code set characters.

-s
Merge subsequent lines rather than one from each input file. Use tab for concatenation, unless a list is specified with -d option. Regardless of the list, the very last character of the file is forced to be a new-line.

Examples


ls | paste -d
-
List directory in one column

ls | paste - - - -
List directory in four columns

paste -d\t\n file1 file2
List file1 in column 1 and file2 in column 2. Separate the columns by a tab.

paste -s -d\t\n file1 file2
Merge pairs of subsequent lines first in file1, then in file2. Concatenate the merged file2 below file1.

Files
