thanks, but I think this might be missing something? I tested it like this:

sed 's/coat (tab) hat$/hat/' myfile > myfile

and it ended up deleting everything else in the file, and all i want removed is 'coat'

maybe i'm the one missing something?? ha.

Get a backup of the original file:

$ perl -lpi.bak -e 's/coat\s*//g' infile

Regards,

thanks for this reply, but will this work on the ONE line if 'coat' appears multiple times within the file?
