Can you help with rename files? (a bit offtopic, sorry)
Hi, I have lots of files named like 07X55c_IMG_0155.png where 07X55c is a random text of varable lengths which I want to cut so that the file will be renamed to IMG_0155.png In my simple-mindedness I just opened mc, selected all the files and typed in the rename dialog replace *IMG* by IMG* The result though, as you for sure knew (but me only now) were files named like IMG07X55c_ - not what I expected :-( No need to say, but anyway: I have not the slightest idea of regular expressions and such sophisticated things, so that I kindly ask you for your help: how can I rename all files in a directory, cutting off the variable length part before "IMG" and keeping all the rest on the right side of IMG unchanged. Thanks for making me a little bit more enlightened!

Daniel There's krename, that did the job for me in similar renaming actions.

Ah, photos. Krename allow you to pick from the exif data the time of creation and with [exifExif.Photo.DateTimeOriginal] after some tinkering you can sort it to something like 20220105_151211_your_photo.png Peter

Besides the already mentioned KRename, you could use mmv that works without regular expressions, too. E.g.: mmv -n "*_IMG_*.png" "IMG_#2.png" This will only print the renamings. Remove the "-n" option or replace it by "-v" to really rename your files. HTH Jan -- The secret of success is sincerity, learn to fake it and you've got it made.

E.g.: % mmv -n "*_IMG_*.png" "IMG_#2.png" % % This will only print the renamings. Remove the "-n" option or replace it by % "-v" to really rename your files. +1 for a handy tool like mmv. Definitely a good way to go if you have it installed. If you don't, there's good ol' shell scripting. Something like for F in *_IMG_[0-9]*.png do NEW=`echo $F | sed -e 's@.*_IMG_@IMG_@` # just strip everything before IMG NEW=`echo $F | sed -e 's@.*_\(IMG_[0-9]*.png\)@\1@'` # grab the pattern you want and keep only it echo mv "$F" "$NEW" # double-check the results and remove "echo " to actually do it done gives you two different ways to calculate the new name. I'm sure there are fancy bash-isms as well, but I'm a very vanilla Bourne guy and like using the standard tools instead :-) awk would be another way to do it, but substring-ing can get busy. % % HTH % Jan % -- % The secret of success is sincerity, learn to fake it and you've got it made.

Thanks for the hints! Both solutions do it for me. In the concrete case I prefer the mmv way for now. For Krename I had to search a bit for how to use a wildcard. It must be used as a regular expression in search/replace and the box "includes RegExp" must be checked. Then it works, too. I wish you all beautiful Christmas, much Love and Peace!

No, I can not predict the result without thinking somewhat hard, something that I refuse to do right now (unless bribed), but I did know that it would result in disaster :-p

Use krename. Yes, I know you have been told twice already, so I will insist: use krename :-) One of the nice things it has is that will run a simulation so that you can see if you like the result without going ahead. Just the thing for us (yes, I confess to not knowing regular expressions besides the simple ones). -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)

If they are all in one directory, just cd to that directory and do: for fnmame in *IMG*.png; do mv "$fname" "${fname#*_}"; done or if in multiple subdirectories feed a while loop with find: while read -r fname; do mv "$fname" "${fname#*_}"; done < <(find the/path -type f -name "*IMG*.png") -- David C.

And if for some reason you are using POSIX shell instead of bash, just pipe the find output to the loop instead of using process substitution, e.g. find the/path -type f -name "*IMG*.png" | while read -r fname; do mv "$fname" "${fname#*_}"; done -- David C. Rankin, J.D.,P.E.
