This script should generate multiple temp files temp1.v temp2.v temp3.v temp4.v
after being processed with sed scripts.
The problem is with the first line
Code:
sed -n '/module '${MODULE}'${c} /,/endmodule/p' prescan.v > temp${c}.v
sed is unable to do variable substitution.
I tried with double quotes also substitution is not happening and getting empty temp files.
The $c should be incremented and the $MODULE1 $MODUL2 should be read depending upon the environmental variable set and the pattern should be searched and temp file should be created.
Please let me how to tackle this issue

Reason: additional code tags
Your quoting is not correct, that ${c} after module will not be evaluated. And, if I infer sort of correctly from what you say, you're trying "dynamic" variables. That does not work that way. As you seem to be using bash, try indirect expansion (see man bash):
You cannot put the redirect into the variable like that and in general you are in for a quoting exercise.
Why not use RudiC's suggestion or
Code:
eval mod=\$MODULE$c
echo "$mod"
And use the latter variable for your substitutions.. There is always a security concern with eval. In this case c is a numerical value, controlled by you..
