bash script to sort files by extension

otheralex · 08-17-2005, 07:01 PM

I'm trying to write a simple bash script to sort files based on their extensions. Mostly this is for sorting images. I would like to be able to go into a directory which may contain any combination of several filetypes and put them into separate directories.

Basically I'm thinking of this being a series of if/thens... sort of like this:

if [ there are any files ending with .tif ]
then
mkdir tif
mv *.tif tif/
fi

and so on for .jpg, .dng, etc...

thanks!

Did you have a specifc question about what you wanted to do?

yes, sorry for not making my original post more clear.

What I don't know how to do is write a script that will look for any files whose names end with a specific extension and if there are any such files, put them in a new directory.

So if the action of the script was written in plain English is would say "if there are any files ending with ".tif" then do the following..."

I hope that clears is up.

Thanks.

It appears you have the concept now you just need to start producing some code. Post something.

Well, you can probably just use pattern matching in the shell. E.g.

Code:

#Move all .txt files to subdir txt.
#Only create txt subdir if at least 1 file with .txt extension exists.
for i in $(ls *.txt); do
   mkdir txt
   break
done
mv *.txt txt
