I see this a lot in bash scripts and I cannot see this in the manual and other sites.
What does the -I in running a perl script mean?
It is run like this:
perl -I$prod_dir $prod_dir/script.pl <parameter1> <parameter2>
Can someone explain it to me?
-Idirectory
Directories specified by -I are prepended to the search path for modules (@INC ).
Source: perlrun documentation
It means perl will include the modules available under specified directory following -I which is $prod_dir in your case.
By default Perl picks up modules from @INC. If you want to use a module which is not available in @INC then you can specify the directory using -I. This specified directory will be appended to @INC at run time.
