By design, there is no <code>/usr/bin/perl</code> in Nix. So you may encounter messages like: | |||
<syntaxHighlight lang=shell> | |||
./myscript.pl: bad interpreter: /usr/bin/perl: no such file or directory | |||
</syntaxHighlight> | |||
Change the first line of the script to | |||
<syntaxHighlight lang=shell> | |||
#!/usr/bin/env -S perl | |||
</syntaxHighlight> | |||
or start it with <code>perl ./myscript.pl</code> | |||
