I'm currently trying to organize several thousand files which are named according to what's in them, and the various "tags," if you will, are separated by spaces. So, for example:

foo_bar bar_foo.txt

I'm relatively new to Linux/Unix, and was wondering if there was a way to iterate through every file, create folders based on the tags, and copy the files to those folders?

So we'd end up with:

./foo_bar bar_foo.txt
./foo_bar/foo_bar bar_foo.txt
./bar_foo/foo_bar bar_foo.txt

So far, I've been manually doing everything like this:

mkdir foo_bar
cp *foo_bar* foo_bar/
mkdir bar_foo
cp *bar_foo* bar_foo/
...

Obviously this is pretty time-inefficient, so I'm just looking for a way to automatically do it.

Edit: Some more examples:

Input:

./a b c d.txt
./b a d.txt
./c d e.txt
./d a.txt

Output:

All original files still in parent directory, plus:

./a/a b c d.txt
./a/b a d.txt
./a/d a.txt

./b/a b c d.txt
./b/b a d.txt

./c/a b c d.txt
./c/c d e.txt

./d/a b c d.txt
./d/b a d.txt
./d/c d e.txt
./d/d a.txt

./e/c d e.txt

try this.. remove the echo.. if you are happy with the commands...

ls * | awk '{print $1}' | sort -u | while read a; do echo mkdir -p $a; echo mv ${a}*txt ${a}; done

modified answer

$ ls
    a b c d.txt  b a d.txt  c d e.txt  d a.txt
$ ls * | sed "s/.txt//;s/ /\n/g" | sort -u | while read file; do echo mkdir -p $file; echo mv *${file}*.txt ${file}; done
    mkdir -p a
    mv a b c d.txt b a d.txt d a.txt a
    mkdir -p b
    mv a b c d.txt b a d.txt b
    mkdir -p c
    mv a b c d.txt c d e.txt c
    mkdir -p d
    mv a b c d.txt b a d.txt c d e.txt d a.txt d
    mkdir -p e
    mv c d e.txt e

Note: as you want the file be present in your original directory.. use cp instead of mv

  • Well, that almost works, but it only sorts by the first tag, so if we had multiple files with the foo_bar tag, but it wasn't the first tag, they wouldn't end up in the same folder. – Swammy Dec 9 '16 at 9:55
  • can you add more input and expected output... more files and which folder it has to go...etc... – Kamaraj Dec 9 '16 at 9:57
  • Alright, I added a few more. – Swammy Dec 9 '16 at 10:03
  • check the modified answer – Kamaraj Dec 9 '16 at 10:11
  • If I just remove the various ".txt"s from your answer, will that make it work with every file type, or would it require further modification? I just used .txt in the examples because it's the most common of all the files we have, but there are some of other types. – Swammy Dec 9 '16 at 10:16
