[SOLVED] Clueless on how to remove spaces from all .jpg's beneath a folder

anon091 · 09-10-2009, 11:43 AM

when i typed n to that line, it said Missing }.

that echo $0 prompted me for the same responses. when i typed n, it said -tcsh

anon091 · 09-10-2009, 11:44 AM

find . -name '* *'.[jJ][pP][gG] | while read file; do echo mv "$file" "${file// /}"; done

that what was i tried to run, FYI

Right, that's what I feared, csh variants are completely different animals. Unfortunately I am not proficient with csh, and I am really no interested in learning it. I suggest you to install bash and run my command in bash. None of the snippets posted in this thread (by me and the others) will work in any csh variant, I think.

Could it be that i have bash but i'm just not in it? how could i tell or try switching over to it?

anon091 · 09-10-2009, 11:54 AM

or should i do a su - and try it maybe?

If you have it installed just running it should work

Code:

bash

Then echo $0 should report "bash" instead of "tcsh". And my command should work inside that new shell. To go back to tcsh you can type "exit". By the way, did you install tcsh voluntarily or did it come by default in your distribution? Most distros nowadays ship either bash as the default shell (and maybe busybox's ash for init, which is lighter).

No, never run massive commands like this as root. You shouldn't operate as root. Only for administrative tasks.

OK, I typed bash then echo $0 and it told me bash!!!

so now i ran the command and a TON of stuff flew by on the screen, the last line being

mv ./06-13-2009/gus/gus new9.jpg ./06-13-2009/gus/gusnew9.jpg

so i guess I should be good to remove the echo right?

So it seems. If you want to be really safe, you could backup the whole directory before running it.

would this be a tar.gz i would be making?

does it show i'm very new to Linux :-)

Whatever suits you, you can use tar or even cp. For example:

Code:

tar cf backup.tar orig_dir/
# or
cp -R orig_dir/ dist_dir

I didn't enable compression because most images surely will already be compressed, so you are going to gain very little from compression and it will take much longer to do the backup if the directory is big. Once you have checked that the renaming went ok you can delete the backup.

We all were at some point

Thanks for all the help man. hopefully i can take it from here, hopefully :-)

Found a small problem. I get a "no such file or directory" error when it tries to remove the spaces from folder names. is there a way to make it do only the files and not folder names as well?

i92guboj · 09-10-2009, 12:57 PM

Using -type f should solve that, in the find part. I changed the examples above (well, in the previous page by now) to reflect that.

anon091 · 09-10-2009, 01:00 PM

ok, so it should have -type f in between the . and the -name, as shown below. i'll give it a shot

find . -type f -name '* *'.[jJ][pP][gG] | while read file; do echo mv "$file" "${file// /}"; done
