San Jose, CA | quick way to remove file extension?
I am a scripting newbie... or maybe this can be done on one line but all I need is to remove the .sav extension off of all the files in the directory...

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
That probably won't work if there is white space in "$1".
It depends on the fact that sh/bash will evaluate "*" as just "*" when there are no matching files.

^^ that would be my prefered name, but I'd wrap things in a few more levels of quotes, such as
for file in "*.sav*; do
mv "$file" "`basename "$file" .sav`"
done
Otherwise, expect borkage with filenames with spaces.
