From the bash manpage:
noclobber
If set, bash does not overwrite an existing file
with the >, >&, and <> redirection operators. This
variable may be overridden when creating output
files by using the redirection operator

The problem with removing and recreating is that if a program has that
file open for appending (e.g. logfiles), the file isn't actually
removed from the disk until that program closes its file descriptor.
So you end up with 3 problems:
1. The file still exists on disk, but is not linked to in any

What about:
rm -f {list of filenames}
touch {list of filen
Summary:
1) > foo
2) cp /dev/null foo
Problems:
1) I use set -C in bash, so I can't say > foo if foo exists wthout
first saying set +C.
2) cp /dev/null foo won't take multiple filenames as arguments
So teh answer is that I do need a script or program to do the job.

A very simple way is ">foo" (noquotes) works in bash. It also creates a
file.

Try this one:
>foo
or, for multiple file names:
for xxx in *
do
>$xxx
done
where * is any regular expression or:
for xxx in a b c d e f g.c h.o g.txt ...
do
>$xxx
done
If your finger are lazier than that, I'm afraid I can't help ;-)
