UNIX for Dummies Questions & Answers

Hello everyone, I may sound stupid for asking this but I have files that need to be loaded onto every system at work. When loaded the files are for example....

5peasw.sim

the end result needs to be

5PEASW.sim

this is for over 50 files in the directory they go to.

I am trying to find out what I can do in order to capitalize all files at once without capitalizing the .sim extension, I did try to cap everything using....

typeset -u t;for f in *;do t="$f";mv "$f" "$t";done
and this worked but it capped the .sim as well....so if anyone can figure out how to just lowercase all the extensions after I do this, or do one bit that capitalizes everything before the extensions than I would be very grateful!
Thank you!

Try:

Code:

for f in *;do 
  name=${f%.*}
  ext=${f##*.}
  name=${name^^}
  mv "$f" "$name.$ext"
done

If all files contain dots an extensions, how about:

ksh:

Code:

typeset -u t
typeset -l e
for f in *.*
do
  t=${f%.*}
  e=${f##*.}
  mv "$f" "$t.$e"
done

It returns with name=${name^^}: bad substitution

That's why you should always explain what your system and shell is in your opening post.

What are they?

it worked! thanks a lot!
