Here are two ways to run temp.pl after creating it:


Eremita:~ jd$ cd
Eremita:~ jd$ echo '#!/usr/bin/perl
print qq~hello\n~;' > temp.pl

Eremita:~ jd$ perl temp.pl
hello
Eremita:~ jd$ ./temp.pl
hello
Eremita:~ jd$

The file does not need permissions changed in this case.

If you omit the shebang the first method will work but not the second:

Eremita:~ jd$ echo "print qq~hello\n~" > temp.pl
Eremita:~ jd$ perl temp.pl
hello
Eremita:~ jd$ ./temp.pl
./temp.pl: line 1: print: command not found
Eremita:~ jd$

If you need to change the permissions on temp.pl to make it executable, then

chmod +x temp.pl
