How can I call a Perl function from a shell script?
-
I have written a library in Perl that contains a certain function, that returns information about a server as a character string. Can I call this function from a shell directly? My boss asks "Can you call it from a shell directly for the time being?" Because he said that, I think I should be able to do it, but how do I do it?

Answer:
perl -MServerlib=server_information -e 'print server_information()' Is another way to do this, but only if Serverlib exports server_information sub. If it doesn't, you would need to do the below instead: perl -MServerlib -e 'print MServerlib::server_information()'

Do you mean something like this? Create a file called serverinfo which contains: #!/usr/bin/perl require 'library.pl'; say library::getServerInformation(); then run: chmod u+x serverinfo then run: ./serverinfo
