small one-line loop, change for different taste :P

for FILE in $(ls); do [COMMAND]; done
# Small for loop, that can list files in dir, and after that executes # [COMMAND] of your choice, usefull for example rename, move, tar etc.. # change cmd's for different results :)

What Others Think

can be easier (as written) or much more powerful. Yours, as written can be accomplished as... for FILE in *;do echo $FILE;done Also, can be made much more selective by doing something like... for FILE in `ls | grep -v badstufff | awk '{print $2}'|`;do [command] $FILE;done

unixmonkey1114: I actually like to do the $(ls) too, especially so I can ls in another directory. For your second proposal, I tend to use "while" rather than "for", like : ls | grep -v badstuff | awk '{print $2}' | while read line; do [command] $line; done which I find clearer somehow.

Note: "while" and "for" are not equivalent in my last comment though. "for" takes spaces aswell as newlines as separator, whereas "while" only takes newlines, so it can be useful for multi-line values.

I often do: for FILE in ...; do echo [COMMAND]; done and then, if satisfied with the commands printed, I repeat the for command without echo
