Maybe, maybe not:
summer@Dolphin:~$ echo this is a word in a line | grep -o wor
wor
summer@Dolphin:~$

This:

summer@Dolphin:~$ echo this is a word in a line | grep  wor     | tr ' ' '\n'  |grep  wor
word
summer@Dolphin:~$

I use two greps because sometimes the input file is fairly large. You can also sort (or sort -u), and it's good to prequalify the data then too.
