So often you need to remove comments and blank lines form configuration files. You can do it in a very easy single step. #grep -v ^$ file.conf | grep -v ^# What it does is grep ^$ from your file. You must be saying I don't have any such character in my file. Actually those characters have their own meaning. ^ begging of the line $ end of the line So searching for ^$ means you are searching a blank line. The -v option invert your search. So #grep -v ^$ matches all the lines except the blank lines. Again the pipe '|' sends those match to another grep command which matches any line begging with '#'. Then -v option again inverts the match giving you all the lines except comment and blank lines. If you want the output in a file rather than screen then redirect it, #grep -v ^$ file.conf | grep -v ^# > newfile For more of the input/output and error redirection visit http://techspalace.blogspot.com/2008/06/devnull-2.html
