Create subdirectory and move files into it

(ls; mkdir subdir; echo subdir) | xargs mv
With this form you dont need to cut out target directory using grep/sed/etc.

What Others Think

why not use the && instead of ; ?? it ll check if the previous command was successfull , if yes then execute the next one : (ls && mkdir subdir && echo subdir) | xargs mv

FYI, you won't move all the files if xargs has to invoke mv more than once. Just a pitfall to be aware of. Neat command!

you could just: mkdir subdir; mv * subdir It will throw an error because you can't move subdir to subdir but will still work.

To handle filenames with spaces in, and allow for xargs invoking 'mv' more than once: (ls -1 && mkdir "$1") | xargs -d'\n' mv -t "$1"

I really wouldn't use && for this. What happens if the mkdir command fails in this snippet: (ls && mkdir subdir && echo subdir) | xargs mv The output of ls alone will be piped to mv, which will try to move everything into whatever happens to be last in the list (possibly overwriting it). Using semicolons means that the 'echo subdir' command still gets called, so mv will try to move into a non-existent subdirectory (which is much less dangerous).
