Using rename script to change multiple files

From: James Egan on 22 May 2010 16:21 I'm trying to use the perl "rename" script to rename batches of files. So if the files are say: 0123.mov 0124.mov 0125.mov I want to rename something like: birthday-01.mov birthday-02.mov birthday-03.mov I've been experimenting with the rename script like this: rename s/\..+$/Birthday-01/ * Can this be done with regular expressions only? I was thinking of trying to use the seq command to get the numeric sequence part of the file names. -Thanks

Regular expressions may contain arbitrary code. With pfind (ilyaz.org/software/tmp) which is a much improved version of `rename', I would do pfind -nosubdir '-var=$c' . '++$c; s/^[^.]*/birthday-$c/' Not what you want? Add a sprintf... (I would do it outside s///, but one can do it inside too with s///e; then one can do ++$c there too...) Hope this helps, Ilya

If so which one? Or do you just want to have consecutive numbers in your new filenames without any relationship to the numbers in the old files? If so then (untested) my @oldnames = ..... #whatever way you get the old names for (my $i = (1..(a)oldnames)) { rename $oldnames[$i-1] "birthday-0$i.mov"; } >Can this be done with regular expressions only?

Really? Double-checking now.... Yes, it appears you are right: "(?{ code })" WARNING: This extended regular expression feature is considered experimental, and may be changed without notice >With pfind >(ilyaz.org/software/tmp) which is a much improved version of `rename', >I would do > > pfind -nosubdir '-var=$c' . '++$c; s/^[^.]*/birthday-$c/' There is no code in this RE. >Not what you want? Add a sprintf... (I would do it outside s///, but >one can do it inside too with s///e; then one can do ++$c there >too...) The /e modifier doesnt' affect the regular expression but only the substitution string. jue
