Re: Unix question

[Charlie Mengler]

Yes & no. There are a couple of different way to solve the problem. 1) Write your own functions/filters to accomplish the desired operations 2) If the only place in the file where double quote marks exists are around the hostname     and all you want to do is get rid of them, the "tr" command could be used. 3) Unix scripts can accept command line arguments which are positionally dependant so you could create a master script which would look like the following driver.sh host1 schemaA driver.sh host2 schemaB driver.sh host9 schemaG etc....................... The inside driver.sh where you want the hostname to appear place a $1 The inside driver.sh where you want the schema    to appear place a $2 HTH & YMMV!

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--Big planet
