Gary,

You need to be careful with the shell globbing technique used above. If
there are a lot of users, then it might barf. Since Sam has now
ascertained what to do, it is simply a matter og re-writing your shell
script :)

-------------
#!/bin/sh

cd /home

for F in * | grep -v samdea; do
  [ !-e $F/.sversionrc ] && {
    sed -e "s/samdea/$F/g;" < /some_dir/.sversionrc >$F/.sversionrc
  }
done
--------------------------

What this does, is it checks that "$F" doesn't already have the file
specified then it'll go ahead, make the substitution and output it to the
appropriate new file.

To answer your original question, Sam, "sed" is the "Stream EDitor" and
allows one to make quick changes to a file by using the concept of
"regular expressions".

Gary, I have changed your regex slightly, so that the substitiution is
done on a global basis to counter for more than one instance.

HTH,
