capturing terminal directory relative path?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

Let's say I am traversing a directory:

/home/BORK/work/test-backfills/cp_test
/home/BORK/work/test-backfills/cp_test/82468
/home/BORK/work/test-backfills/cp_test
/home/BORK/work/test-backfills/cp_test/82480
/home/BORK/work/test-backfills/cp_test
/home/BORK/work/test-backfills/cp_test/82485
/home/BORK/work/test-backfills/cp_test
/home/BORK/work/test-backfills/cp_test/82490
/home/BORK/work/test-backfills/cp_test
/home/BORK/work/test-backfills/cp_test/82767
/home/BORK/work/test-backfills/cp_test
/home/BORK/work/test-backfills/cp_test/82802
/home/BORK/work/test-backfills/cp_test
[download]

I need to isolate the terminal directory path (in this case, 82468, 82480, 82485, etc) because they are ids that I need to insert into xml documents. I've been looking at the various file modules in cpan, but I can't figure out what to use. Maybe File::Spec? Any examples would be much appreciated.

What you probably want is `File::Basename`. It's in the core already (ie. no need to install it). Try: `use strict; use warnings; use File::Basename; my $base = basename("/home/BORK/work/test-backfills/cp_test/82802"); # Note that $base is now '82802'` [download] s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/	[reply] [d/l] [select]

sort your strings, and then compare them using index. Potentially split them into their parts: `/home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test/82468 /home/BORK/work/test-backfills/cp_test/82480` [download]	[reply] [d/l]

I agree that File::Basename is the robust way to do what you need. But maybe the below code is something you might want to consider as well. #!/usr/bin/perl use strict; while (<DATA>) { print + (split( /\// ))[-1] if /\d+/; } __DATA__ /home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test/82468 /home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test/82480 /home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test/82485 /home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test/82490 /home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test/82767 /home/BORK/work/test-backfills/cp_test /home/BORK/work/test-backfills/cp_test/82802 /home/BORK/work/test-backfills/cp_test [download]	[reply] [d/l]
