I want my perl script to correctly parse two command line arguments separated by a space into two variables:
$ cat 1.pl
print "arg1 = >$ARGV[0]<\n";
print "arg2 = >$ARGV[1]<\n";
$ perl 1.pl a b
arg1 = >a<
arg2 = >b<
$ perl 1.pl "a b"
arg1 = >a b<
arg2 = ><
$
Is there a generic way of dealing with this rather than trying to detect whether quotes were used or not?
The data is passed to Perl by the shell.
program a bwill sendaandbprogram 'a b'will senda bprogram "a b"will senda bprogram a\ bwill senda bPerl has, AFAIK, no way of telling the difference between any of the last three.
You could
splitevery argument on spaces, and that would get the effect you are describing … but it would mean working in a different way to every other application out there.
