The simplest method to use variables in a sed command is to enclose your sed command in double quotes ( ") instead of single quotes ( '). Because the shell performs variable substitution on double-quoted strings, the shell will substitute the value of any variables you specify before sed executes.
For example, the command sed "/$DEL/d" file1 > file2 deletes all the lines in file1 that contain the value stored in the variable $DEL. --------------------------------- Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing -- http://mm.ilug-bom.org.in/mailman/listinfo/linuxers
