[SOLVED] Simple SED with rename

thund3rstruck · 01-18-2012, 04:08 PM

just curious as to why this command fails to rename my files:

Code:

$ rename -v "s/HDTV.*/mkv/g" *.mkv
$ ls
Archer.S01E01.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E02.720p.HDTV.X264-LiLDiCK.mkv
Archer.S01E03.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E04.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E05.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E06.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E07.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E08.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E09.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E10.720p.HDTV.x264-immerse.mkv
idx.txt

I tested the sed expression and that works fine.

Code:

$ cat idx.txt && cat idx.txt | sed "s/HDTV.*/mkv/g"
Archer.S01E01.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E02.720p.HDTV.X264-LiLDiCK.mkv
Archer.S01E03.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E04.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E05.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E06.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E07.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E08.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E09.720p.HDTV.X264-DIMENSION.mkv
Archer.S01E10.720p.HDTV.x264-immerse.mkv

Archer.S01E01.720p.mkv
Archer.S01E02.720p.mkv
Archer.S01E03.720p.mkv
Archer.S01E04.720p.mkv
Archer.S01E05.720p.mkv
Archer.S01E06.720p.mkv
Archer.S01E07.720p.mkv
Archer.S01E08.720p.mkv
Archer.S01E09.720p.mkv
Archer.S01E10.720p.mkv

What am I missing? Does the rename command have some funky deal where it can't do RegEx?

Just wondering...

thanks in advance

You probably have the old version of rename that doens't take a regex. You want the one from the Perl distribution.

Ugh... yup, Fedora rename program doesn't support RegExp

Code:

$ rename -V
rename from util-linux 2.20.1

Download Perl version of rename

Wow that's so weak!

Thanks....

As mentioned, the "rename" that uses that syntax is actually the prename perl script. It comes standard with the perl package, in Debian-based systems at least, and it's automatically aliaed to rename through the alternatives system.

If you have perl installed on Fedora or another non-debian system, I really want to know if also supplies prename for you too, but just doesn't set it up as the default.

I have perl installed and I had no prename script. I had to download it manually and then move it to /usr/local/bin

Code:

$ locate prename
/home/lisa.bailey/Downloads/prename.txt
/usr/local/bin/prename

$ find / -type f -iname prename* 2>/dev/null
/usr/local/bin/prename
/home/lisa.bailey/Downloads/prename.txt
