Camilo,
Basically, it's a UNIX function that squeezes files together. It is short
for "concatenate." Simple example:
cat file1 file2 > file3
Use your manpage for further info:
man cat
You can also use it to view the contents of a file, similar to 'more' or
'less.' Example:
cat file1
will print the contents of a file. Word to the wise: This will display the
guts of a huge binary file too, so unless you *want* to see a bunch of
cryptic garbage scrolling through your x-term, stick to using it on
ascii-based files like text/html/xml.
On an unrelated note, unless my e-mail software is changing the alignment of
your message, your "Perl signature" would not work. When you create a HERE
doc, the closing label has to start at the very beginning of the line, and
there has to be a return or newline after it.
