reading the parameter from another file - Shell Programming and Scripting

dsravan · #1 12-19-2007

I have a script where 3 parametrs are passed to it and it creates the file for each site form a template. If i want to
get the 3rd parameter (which is the site) passed to the script to come from another file how I can change the script tp acheive it?

Here is my script:

Quote:

update.ksh 20071912 1 ind

what i have in the sciprt is simple sed commands.

I need the 3rd parameter to be read from the another file and run it recursively to create 20 different files.

The site file has 20 entries and hence it needs to create 20 files.

Can some body let mw know how i can do that?

assuming '/path/to/siteFile' containts one 'site' per line.

Code:

#!/bin/ksh

for site in $(< /path/to/siteFile)
do
 update.ksh 20071912 1 "${site}"
done

Code:

#!/bin/ksh

for site in $(< /path/to/siteFile)
do
 update.ksh 20071912 1 "${site}"
done
