<h3>Description</h3>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Concatenates a file, or a series of files, to a single file or
|
||
|
|
the console. The destination file will be created if it does
|
||
|
|
not exist, though the the <var>append</var> attribute may be
|
||
|
|
used to alter this behavior.

<a href="../CoreTypes/fileset.html">FileSet</a>s and/or <a
|
||
|
|
href="../CoreTypes/filelist.html">FileList</a>s are used to
|
||
|
|
select which files are to be concatenated. There is no
|
||
|
|
singular 'file' attribute to specify a single file to cat -- a
|
||
|
|
fileset or filelist must also be used in these cases.

<a href="../CoreTypes/fileset.html">FileSet</a>s are used to
|
||
|
|
select files to be concatenated. Note that the order in which
|
||
|
|
the files selected from a fileset are concatenated is
|
||
|
|
<i>not</i> guaranteed. If this is an issue, use multiple
|
||
|
|
filesets or consider using filelists.

<p>
|

|
|
<a href="../CoreTypes/filelist.html">FileList</a>s are used to
|
||
|
|
select files to be concatenated. The file ordering in the

files are concatenated.
