Re: ***** Parameter file in a shell script *****

As long as the parameterfile contains assignments, as shown, you can simply execute the parameterfile within your script When you do so with the command:
. script.par
the file doesn't have to be executable. Mind the . and the space behind it. This lets your script.par be executed within the same shell process as your script self, and makes the parameterfile an initialisation script.

Another way might be:

# Start of your script

.
.
.

name=`grep name script.par|sed 's/.*=//'`;export name city=`grep city script.par|sed 's/.*=//'`;export city

.
.
.

rest of script

# Start of your script

.
.
.

export name=`grep name script.par|sed 's/.*=//'` export city=`grep city script.par|sed 's/.*=//'`

.
.
.

rest of script

Can be enhanced, but I have no time to elaborate right now.
