shell: remove pattern from file name

Question

within workdir I have many filles with the names in the following format:

7000_grid12_10_lig_cne_767_lig.dlg

I need one line sed (or other shell utility) expression suitable to substitute _grid12_ to _ , so the filename become

7000_10_lig_cne_767_lig.dlg

I've tried to use rename for all filles but it did not work (verbose found nothing)

rename -v 's/_grid12_/_/' *.dlg

You can use perl-rename (there is another program called rename which is a part of util-linux package):

perl-rename 's,_grid12_,_,' *

You don't even need a loop as perl-rename will rename all files in the current directory.

it seems that this script has not been installed on the linux cluster where I handle with the filles :-) -bash: perl-rename: command not found – user3470313 Oct 12 '20 at 10:11
What OS are you using? – Arkadiusz Drabczyk Oct 12 '20 at 10:11
I've tried it on MAC as well as on our linux multi-cpu cluster (sorry I don't know what is the OS there ).. this is why I looked for sed sollution, which probably also could be used without loop just via regular expessions.. – user3470313 Oct 12 '20 at 10:12
Try with simple rename instead of perl-rename – Arkadiusz Drabczyk Oct 12 '20 at 10:14
already tried using the same syntax but it did not work .. – user3470313 Oct 12 '20 at 10:16
