remove characters in linux kde CentOS 7 in a bunch of filenames

[thebeesknees22]

Yo yo!

there are smart people here and google is failing me.
say I have a file blahblah_poop.1001.exr 1002, 1003 etc.. and I want to remove _poop in all files

I tried
rename 's/_poop//g' *.exr but something's not right. I tried sed too

Any linux dudes that can lend a brother a hand? I'm on Cent OS7 and kde. blahblah

and I don't have install or download privileges so i can't install any handy tool to do it.

I'm not a linux expert and dealing with regex is always awful, but maybe you need to specify some capture groups, then re-assemble those into your new name.

Something like
rename 's/(.*)(_poop)(.*)/g' '$1$2' *.exr

Maybe? ¯\_(ツ)_/¯ I probably have end part wrong with the dollar signs, you'd have to look that bit up.

actually got it!
turns out our version of rename came from the utils_linux junk and the 's/' stuff doesn't work with that 💆‍♀️ 🤦‍♀️ 💆‍♀️ 🤦‍♀️


thanks @TedEH ! I think that would have worked if we had the regular version of rename
