listing files by type ignoring case in BASH

[mikeym]

Hi

I have been trying to do this for a couple of days now with no sucess. I want to select a list of files by their file extension - ignoring their case - in a BASH script.

I want to select all the par2 files of the form

abc.Par2
def.PAR2
ghi.par2
jkl.paR2
mno.pAr2
pqr.PaR2

But not files such as,

abc.VOL00+001.PAR2

I thought the following should work but I can't use the ignore-case switch at the same time as the print or delete commands:



PARLIST=$(ls *.* | sed -n -e '/.vol[[:digit:]]\++[[:digit:]]\+.par2$/di' -e '/.par2$/pi')

I'm still stuck on this one. I'm not sure that sed is the way forward any more. I have seen mention of programs like super-sed on the web that do case insensitivity, but there must be a way to do this in standard BASH.

I think this would work:


find . -iname '*par2' | grep -vi '.vol[[:digit:]]\++[[:digit:]]\+.par2'

But you could probably do it with 'find' alone.

Thanks that works.

Also i have jsut discoveded what I was doing wrong with sed. The 'i's had to be in upper case, like so:



ls *.* | sed -n -e '/\.VOL[[:digit:]]\++[[:digit:]]\+\.PAR2$/Id' -e '/\.par2$/Ip'
