You could also read the filenames from STDIN while allowing to pass extra arguments via @ARGV like so:
#!/usr/bin/perl
use strict;
print "Info: ARGV is: @ARGV\n";
while (<STDIN>) {
chomp;
next if /^\s*$/; # skip empty lines
if (-e $_) { # a regular file (might be suited to your needs)
# do something with $_ as if it were shifted from @ARGV
print "handling file: $_\n";
} else {
warn "no such file: $_ \n";
}
}
__END__
usr@host:tmp> ls -1 file*.pl | fileabove.pl arg1 arg2 arg3
Info: ARGV is: arg1 arg2 arg3
handling file: fileabove.pl
It could be used i.e. this way:
ls -1 *.dat | fileabove.pl
or
fileabove.pl < filenames.txt
But finally it depends on your needs, which I might not have fully understood...
Update: Added the shebang-line to get rid of extra-calls to perl executable.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
