This pertains to the second item you bring up. I'm not 100% sure why you need to 'do it all in one go' as you say, so this may or may not be helpful. But, adapted from a node by an anonymous monk posted here, you can generate a list of directories within a specified directory.

You can use this to make your script adapt in case the number of or name of directories varies from run to run.

This:
#!/usr/bin/perl -w use Data::Dumper; while(<*>){ push(@files,$_) if(-d "$_"); } print "\n". Dumper(@files) ."\n";
will produce output like this:
sean@seanc:~/code/temp$ ls -l total 16 drwxr-xr-x 2 sean sean 4096 2008-09-17 09:12 dir1 drwxr-xr-x 2 sean sean 4096 2008-09-17 09:12 dir2 drwxr-xr-x 2 sean sean 4096 2008-09-17 09:12 dir3 -rwxr-xr-x 1 sean sean 155 2008-09-17 09:11 dir_list.pl -rw-r--r-- 1 sean sean 0 2008-09-17 09:12 file1 -rw-r--r-- 1 sean sean 0 2008-09-17 09:12 file2 -rw-r--r-- 1 sean sean 0 2008-09-17 09:12 file3 sean@seanc:~/code/temp$ ./dir_list.pl $VAR1 = 'dir1'; $VAR2 = 'dir2'; $VAR3 = 'dir3';
so you can always have an up-to-date list of subdirectories, and the code looks prettier than having a big, long hard-coded list.

Changing the '-d' to a '-f' would give you a list of files, so you could adapt that to get a list of directories, then get a list of filenames or check for the presence of a particular file.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
