I've got an array reference and I'm trying to figure out how many elements are in it. I've tried '$#arrayref', '[EMAIL PROTECTED]', '$(@($arrayref))', and probably a few others that I've forgotten. What is the correct way to do this?
you can try @{EXP} or $#{EXP}+1 where EXP is your array reference:
[panda]# perl -le 'print $#{[1,3,5,7]}+1' 4 [panda]# perl -le 'print @{[1,3,5,7]}+0' 4 [panda]#
the '{}' is sometimes optional depends on EXP, i usually use it for personal perference.
'$#{$arrayref}+1' worked for me. Thanks. Once again, I don't know what I'd do without the people on this list.
