In the first two forms, concatenates corresponding lines of the given
input files file1, file2, etc. It treats each file as a column or col‐
umns in a table and pastes them together horizontally (parallel merg‐
ing). In other words, it is the horizontal counterpart of cat(1) which
concatenates vertically; i.e., one file after the other. In the option
form above, replaces the function of an older command with the same
name by combining subsequent lines of the input file (serial merging).
In all cases, lines are glued together with the tab character, or with
characters from an optionally specified list. Output is to standard
output, so can be used as the start of a pipe, or as a filter if is
used instead of a file name.
recognizes the following options and command-line arguments:
Without this option, the new-line characters
of all but the last file (or last line in case of the
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 replace
the default tab as the line concatenation character.
The list is used circularly; i.e., when exhausted, it
is reused. In parallel merging (that is, no option),
the lines from the last file are always terminated
with a new-line character, not from the list. The
list can contain the special escape sequences: (new-
line), (tab), (backslash), and (empty string, not a
null character). Quoting may be necessary if charac‐
ters have special meaning to the shell. (For example,
to get one backslash, use ).
Merge subsequent lines rather than one from each input file.
Use tab for concatenation, unless a list is specified
with the option. Regardless of the list, the very
last character of the file is forced to be a new-line.
