Hi,
I want to write a program that does check the appropriate system path
for perl in FreeBSD and Linux.
The path where I have it in FreeBSD is
#! /usr/local/bin/perl
and the path where it is in Linux is
#! /usr/bin/perl
I wanted the program to check for the uname of the system and choose
the appropriate path. Can anyone tell me how can I have my program
check this.
This is not a Perl question. The path on the #! line is not used by
perl, but by your operating system. In general, there is no way to put
any logic into that line, though
#!/usr/bin/env perl
may do what you want. Note that it will use the perl in your current
PATH, which may be a security risk. As others have said, you are much
better off arranging for perl to be available as /usr/bin/perl, or
writing some sort of installation script that changes the #! line.
