Thanks for your response. I think perhaps I have been too verbose in my explanation. What it boils down to is this.....
If I have the following variables set up for an iteration:
c=1
n=2
sl1=10
Is it possible (with eval or any other tool for that matter) to assign the value of sl1 to an (as yet undefined) variable called $di1sl2.
This would be easy enough if the name of $sl1 and the undefined variable did not change for every iteration.
So the way I see it happening (in psuedo-code) would be:
Then when you:
You should get:
10
Hopefully you can now see my issue, namely that the variable that contains "10" will be differently named for each iteration (it could be $sl1, $sl2 $sl3 etc). so this means that eval will need to deal with a "variable within a variable" - notice the two pairs of curly braces in the same variable in the example above.
Does this make it any clearer?
Many thanks....

I have a requirement of writting the shell script where it should ask me two values

Greetings all,
Been trying to do my Googling and forum searches but can't seem to lock in on a solution.
I have a script that parses a log and collects all the uniq events to a flat file. Some days might have 50 unique events, other days might have 75. (Hence my reference to dynamic.)

Hi all,
I want to dynamically set variables in a bash script. I made a naive attempt in a while loop that hopefully can clarify the idea.
n=0; echo "$lst" | while read p; do n=$(($n+1)); p"$n"="$p"; done
The error message is:
bash: p1=line1: command not found
bash: p2=line2: command... (8 Replies)
