I was messing around with the debugger today, and I found that (as advertised) 'perl -de 0' would dump me into the debugger, but that 'perl -ed 0' just put me back to my prompt. I'm just curious. Is this behavior correct? Are there other options that must be given in a particular order?

Correct according to whom?
It could be made to work the way you expect, but that would be complicated.
: Are there other options that must be given in a particular order?
The -I option also requires a following argument, except that you can
have no intervening space if you like. In other words, if you said
perl -Id /usr/local/lib/perl whatever
you would add 'd' to the @INC array, and then it would try to execute
the directory /usr/local/lib/perl as a perl script, which probably won't
do anything useful.
The -D and -i switches also must be the final switch in a bundle.

Calling 'perl -ape' works as documented, while 'perl -pea' seems to ignore the 'a' and behave like -pe. Same goes for -ane and -nea. -- Ran ----------------------------------------------- Reply-To: crehta@taux01.nsc.com (Ran Ever-Hadani) Disclaimer: The above is to be attributed to me only, not to any organization.
