The <code>paste</code> command is used to join files horizontally
|
||
|
|
(parallel merging) by outputting lines consisting of the sequentially corresponding
|
||
|
|
lines of each file specified, separated by tabs, to the standard output.<br>
|
||
|
|
Once involved, <code>paste</code> will read all its file arguments. For each corresponding line,
|
||
|
|
paste will append the contents of each file at that line to its output along with a tab.
|
||
|
|
When it has completed its operation for the last file, <code>paste</code> will output a newline
|
||
|
|
character and move on to the next line.
|

|

|

|
|
<pre>
|
||
|
|
paste [flags] [file1] [file2] ...
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<h3>Flags</h3>

|
|
|

|
|
<ul>
|
||
|
|
<li><code>-d</code> delimiters, which specifies a list of delimiters to be used instead of tabs
|
||
|
|
for separating consecutive values on a single line. Each delimiter is used in turn;
|
||
|
|
when the list has been exhausted, paste begins again at the first delimiter.
|
||
|
|
<pre>
|
||
|
|
paste -d "|" file1.txt file2.txt
|
||
|
|
paste -d "|," file1.txt file2.txt</pre>
|
||
|
|
</li>
|
||
|
|
<li><code>-s</code>, which causes paste to append the data in serial rather than in parallel;
|
||
|
|
that is, in a horizontal rather than vertical fashion.
|
||
|
|
</li>
|
||
|
|
</ul>
