I have a folder with around 150 text files. I would like to create folders in the name of the 150 files. After that I would like the text file to be moved to its respective folder.

Example names of the files inside myfolder directory:

       |______ ajhaslf.txt
       |______ oiueed.txt
       |______ dsflije.txt

How I would like my new structure to be:

       |______ ajhaslf
       |______ oiueed
       |______ dsflije

Of course creating directory with the filenames is not a problem for me with mkdir.

    cd into your folder and: for file in *.txt; do mkdir -- "${file%.txt}"; mv -- "$file" "${file%.txt}"; done Jun 27 '14 at 12:01
  • mkdir: cannot create directory ‘GmZzz3StdPk.txt’: File exists

  • Are you sure you copied the line I gave (especially the "${file%.txt}"? What is your shell? Jun 27 '14 at 12:08
  • @gniourf_gniourf: Yes, I copied the same thing and tried. My shell is bash

    Do you have a file named GmZzz3StdPk.txt.txt? Jun 27 '14 at 12:18

@gniourf_gniourf has the right idea:

set -o errexit -o nounset
cd ~/myfolder
for file in *.txt
    mkdir -- "$dir"
    mv -- "$file" "$dir"

This should be POSIX compliant. It is not re-entrant. It will not work if you have any two files named something.txt and something.txt.txt.

    Maybe mkdir -- "$dir" && mv -- "$file" "$dir" to make sure we don't execute uncontrolled commands. Otherwise it's perfect. :D. Not sure though about the something.txt.txt thing; that was my first thought but now I believe that something.txt would come before something.txt.txt in the expansion of *.txt. Jun 27 '14 at 12:26
  • @gniourf_gniourf errexit to the rescue. For the duplicate suffix, cannot create directory GmZzz3StdPk.txt definitely means that it fails when processing GmZzz3StdPk.txt.txt, independently of the files' sequence in the output.

  • And how about shopt -s nullglob too, to be sure we're on the safe side? :D. Jun 27 '14 at 12:30
  • That depends on whether there being no matching files is an error or not.

  • So then shopt -s failglob? Jun 27 '14 at 12:32
