When using shebangs (#!) in Perl scripts, there are several common pitfalls and gotchas that can affect portability across different environments. Here’s an overview of some of these issues:
/usr/bin/perl
, while others might have it at /usr/local/bin/perl
. Using /usr/bin/env
can help mitigate this issue.By being aware of these pitfalls, you can increase the portability of your Perl scripts across different systems.
Here’s an example of a shebang line that increases portability:
#!/usr/bin/env perl
