[solved] Remove words from file using a list variable?????

orphius1970 · 2010-04-22 10:09:33

Is it possible with bash, to create a script that will scan a text file and remove words that are set in a list?
I have a file with words like so:
word1
word2
word3

I would like to be able to set script to scan file and remove only the words (and spaces left) that are in a list,
that is inside script. Is this possible???

concatentate all the words in the list then use sed with "or" expressions (|), e.g

$ sed s/"hal\|netmask"// /etc/rc.conf

sorry I am new to scripting and Have NEVER used sed.
Can you explain a little better?

Ok i tried it and understand a little better. However,
It left space behind. How do I fix that?
Also, how do I get it to save the file with the changes?
Sorry If I seem so noobie
