This is a long process and my script takes close to 10 minutes to complete. What I want to know is that whether this can be optimized or not ? Is is possible to run one grep command and find out the number of time StringA, StringB and StringC has been called individually ?
can anybody let me know how can i search for "-n" in a text file; or if my file name is "-n" (which is legal in Unix) how do i deal with that?
