Thanks for your replay

Oooopsss.... i didnt know that about MS word... learned one more thing Smilie

you are right, this does work and dont need arrays but

people with the same fist name and last name should do to one file; not people with same first name only.
output file 1 ---- ruby smith
output file 2 ---- ruby brown
output file 3 ---- ruby green

when I used the egrep the way mentioned but it is not taking out the lines with people who have a middle name for example

NAME
gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression SYNOPSIS
gzgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
gzgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci- fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If gzgrep is invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, gzgrep uses it as the grep program to be invoked. For example: for sh: GREP=fgrep gzgrep string files for csh: (setenv GREP fgrep; gzgrep string files) AUTHOR
