search and replace in a file 1

[dwcasey]

This works fine...it searches onconfig and looks for
LTAPEDEV /dev/infmx/log_tape_dev

And replaces with
LTAPEDEV /dummy

perl -pi -e 's/LTAPEDEV \/dev\/infmx\/log_tape_dev/LTAPE \/dummy/g' onconfig

What can I do so that if there is extra spaces ( white space ) between LTAPEDEV and /dummy and make sure the search/replace still works?

you mean "and /dev", as /dummy is on the right side of the replacement:

perl -pi -e 's{LTAPEDEV\s+/dev/infmx/log_tape_dev}{LTAPE /dummy}g' onconfig
