You need the following packages (from your CD or mirror site)
   Bastille-Tk-module-1.2.0.rc3-0.1mdk
   Bastille-Curses-module-1.2.0.rc3-0.1mdk
   Bastille-1.2.0.rc3-0.1mdk

This works from command line...

   # if [ `ps -efw | grep -v grep | grep rerf |wc -l` -eq 0 ] ; then
echo 'yes' ; else echo 'no' ; fi

In a shell script, make it more readable...
if [ `ps -efw | grep -v grep | grep rerf |wc -l` -eq 0 ]
then
   echo 'yes'
   # more statements here, etc.
else
   echo 'no'
fi 

-
Also, analias command that I use *often* is
# alias psg
alias psg='ps -efw | grep -v grep | grep'

This avoids seeing the 'grep' that is forked off by your request.

Thanks...Dan

Renaming...

For your needs, you would want something like...
for NAME in `find www_root -name "q*tif.bz2" -type f` ; do
mv $NAME `echo $NAME | tr '_' '.'
done

Only problem might be that *all* underscores will get changed.

The real problem is that the file is in DOS format, instead
of *nix. So it has the wrong end of line format. Look through
the archives or deja news for answers on how to fix this.

Thanks...Dan.
