Ok, my perl-fu is non-existent. I have a dir on an FTP server that contains multiple files that have a naming structure like so a_20061002201644_b_R01C002_c_30_d_81230_e_FOO_f_02_g_blah.txt the value d_<whatever> will be a number that is actually can be mapped to a name for example, 81230 will be jsmith 82111 will be mdoe etc. I want to replace the number string with the name in each of, say 500 files & run it out of cron pointers or clues would be welcome. I am militantly unopposed to using *any* tool, (perl, php, sed & awk or waving dead chickens) to get the job done -- Tony Placilla, RHCT, GSEC anthony_placilla@xxxxxxxx GPG-Key-ID: 1024D/C78F8B64 http://pgp.mit.edu Key fingerprint = A8D5 7AFF CE88 4179 C792 D9A9 F197 2A15 C78F 8B64
