Untested code coming...
#!/usr/bin/perl
my $pattern = "PGP";
&renameFiles('/home/user/perl/testincoming');
sub renameFiles {
# Pass directory name as parameter
my $Dir = shift;
opendir(DIR, $Dir) || die "Can't opendir $Dir: $!";
my @Files = grep { -f "$Dir/$_" } readdir(DIR);
rewinddir(DIR);
my @Dirs = grep { /^[^.].*/ && -d "$Dir/$_" && ! -l "$Dir/$_"} rea
+ddir(DIR);
closedir DIR;
foreach $file (@Files) {
open(FILE,"<$Dir/$file") || die "Can't open $file: $!";
my $doRename=0;
READFILE: while (<FILE>) {
if (/\Q$pattern\E/) {
$doRename=1;
last READFILE;
}
}
close(FILE);
if ($doRename) {
my $newname=$file;
$newname=~s/^./o/;
rename ("$Dir/$file", "$Dir/$newname");
}
}
# Call self for each subdir
foreach $SubDir (@Dirs) { &renameFiles(join("/",$Dir,$SubDir)); }
};
Should rename all files containing a PGP line in the whole subdirectory tree.
This is just a quick modify of something I already had, so it may contain bugs, etc...
I'm not responsible for what it does to your system, no warraty, etc, etc. You know the standard phrases.
UPDATE:As merlyn humbly suggests in his post, I now check for symlinks with && ! -l "$Dir/$_". The code is still
untested from my part.

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

or How to display code and escape characters
are good places to start.
