quick way to remove file extension?

info rename

reply to laura
my bad this is on Solaris and rename doesn't seem to exist

reply to laura
It isn't clear whether you want to rename the files, or you want to make available to your script the name without extension. If you are scripting a rename, you need both.

The "basename" command will give you the file name without extension.

For renaming, try something like

for file in *.sav
do
    mv $file `basename $file .sav`
done

New question... if I wanted the user to provide a file extension as an argument and I process it within the script.. how can I check that at least one file exists?

if [ -e *$@ ] does not work

I would maybe try:

for file in "*.$1"
do
   if [ "$file" = "*.$1" ] ; then
      echo "No files match *.$1"
      exit 1
   fi
   mv $file `basename $file ".$1"`
done

for file in *.sav
do
    mv $file `basename $file .sav`
done

for file in "*.sav*; do
  mv "$file" "`basename "$file" .sav`"
done

rename .ext " " *.ext
