    Hi geeks ,
    How can I do substr and instr kind of operaion     in unix shell script . is it possible ?     like i have one paramter as "hostname" .. I     want to trim quotes surrounding the hostname .     One more question , is possible to read another     text file line by line using a shel script and then edit that file     .
    Actually I have this configuration file for my     system which have keywords like $HOSTNAME$ , $SCHEMA$ which I want to     replace with actual values at the time of installation by asking questions     to the user.
     
    TIA
