Am trying to run a exe on my unix machine from a different folder.

For instance,
i have a perl file in a folder /home/asif/runprj.pl which runs a exe in a different folder /home/projects/cobsat/a.out

and my perl file is something like this

#!/usr/bin/perl
system("/home/projects/cobsat/a.out");

now ...is there anyway I can run the exe by actually getting into the cobsat directory and simply execute ./a.out instead of runnin it with absolute path.

If you are using perl then try using the chdir function.
