Thanks for the replies. This suggestion won't do the job as the list of
words is very long, maybe 50-60. This is why I asked how to place them all
in a file. One reply dealt with using a file with egrep. I'll try that.

Appreciate the help and any others in case the one doesn't work.

All the best,
Jack
