That said - DO NOT agglomerate zillions of user data files adhoc in one file tree.
It is completely possible to have parked those files into meaningful directory names - i.e., the text you are using as a key. Then you can simply look for a directory and go from there. Pre-planning beats kludge like this every time.

Concur! Especially for the last Sentence!

True. Here is my take at it, based on yours. The rationale is that after the first scan the inode list is cached in memory and the next finds will go a lot faster:

Code:

while read FILEMASK ; do
     find /path/to/sourcedir -type f -name "*${FILEMASK}*" |\
          while read MOVEFILE ; do
               FNAME="${MOVEFILE##*/}"
               if [ -f "/path/to/targetdir/$FNAME" ] ; then
                    mv "$MOVEFILE" "/path/to/targetdir/${FNAME}.$$"
               else
                    mv "$MOVEFILE" "/path/to/targetdir"
               fi
          done
done < /path/to/list.of.filemasks

Note that no security provisions are put into place: checks for exhausted diskspace, successful move operation, etc.. are all missing and you should add them before putting this sketch into a fire-and-forget script.

I hope this helps.
