parameter to perl -p -i -e s/ command from .sh script

[liveunix]

#!/usr/bin/bash
RUN=R1
filename=f1

perl -p -i -e 's/qq{$RUN}/\|\d\d\d\d\|[A-Z]*/R3/i' $filename

I am expecting $RUN to be expanded by shell
Also plz note my file f1 is like this
R1|1000|SUCCESS
and i am replacing it by
R3

Please let me know what is wrong in this?

Thanks

I have never done bash variable interpolation like that, so I don't know the proper syntax to get it to work. Nevertheless, assuming that you can get that part to work, the regular expression that you'll want would be this:

perl -pie 's/R1\|\d{4}\|[A-Z]*/R3/i' $filename

Therefore remove the qq{} enclosing $RUN, unless this is necessary for the variable to be interpolated, and also remove the / after that as well.
