Using ls output for other process

Hello,

Just to set the tone: I am a complete UNIX noob (i guess you see that excuse popping up frequently here but anyhow)
Now here's my bloody simple problem which needs to be quite urgently resolved: I have a number of files in a directory, for which the ones, relevant for executing a subsequent action, can be easily gathered using an ls -1 | cut -c1-5 command. What I want to do know is plug in each filename resulting out of this ls command into another command. Hence, I need to temporarily store each name into a variable, execute the other command by using that variable and then move on to the next one untill the list is finished.

PS: if someone knows a fool proof unix guide on the web which enables even an amoebe to learn unix, feel free to post the link.

Thanks.

This comes close but not yet perfect. Now "i" is filled with just the regular filename, but I need to have that string made shorter with the cut command.
