J.,
Thanks for your suggestions. While googling comp.unix.shell today, I found yet
another method. I was not aware that "*" when used by itself matches every filename
in a directory. Apparently, part of the problem I was having was a side effect of ls
and find. Here is the script that I used:
#!/usr/bin/bash
for file in *
do
newfile="`echo "$file" | tr '[:blank:]' '[_*]'`"
mv "$file" "$newfile"
done
I also learned something important about tr. I was using [:space:], but that is not
appropriate here. [:space:] includes horizontal as well as vertical whitespace. That
means I was transforming linefeeds as well as spaces. [:blank:] is exclusively
horizontal whitespace, which is what I needed.
Thanks to all of you who contributed. I appreciate your help.
Cheers,
Sean
