I'm using a script to build a file by concatenating portions of two 
other files. Then end result needs to be checked to make sure a certain 
word shows up in a line.

I know that "grep programm <this email message>" would return the line:

but what I want returned is just the word "programmer".
   

sed -ne 's/^.*\(word_here\).*$/\1/p' < file
BTW, why not simply
        if grep -q word file
        then
                # word was present in file
                bla
                bla
        fi
Or "if ! grep -q word file" if you want to do something if word
wasn't present in file.
 

Because:
[EMAIL PROTECTED]:~$ grep -o wor.* /var/cache/debconf/templates.dat | tr ' 
' '\n' |grep wor.* | sort -u | head
"select-default-wordlist".
'select-default-wordlist'
'select-default-wordlist'.
'select-default-worldlist'.
