Hello!

I am attempting to set a shell (bash) environment variable from within a Perl script but I have not been able to come up with a satisfactory solution. In particular, I am attempting to set the CVSROOT environment variable so that I can use the "system()" syntax to execute cvs commands. I had hoped the following syntax would work: 

system "export CVSROOT=<cvs>"

It does not.

Another solution would be to create a shell script on the fly which would contain a command to set the environment variable. My Perl script would then execute the shell script. This seems pretty messy.

Is there a better solution?

Thanks in advance!
