Re: help figuring out what a section of script does

It's reading a file of sql insert statements like this:

INSERT INTO FOO VALUES (1,2,3,4,5,X'6789')
[download]

It uses the first three numbers to build a filename. The X'' part at the end is hexadecimal-coded. It decodes that part and writes it to the file. The decode loop of the script would be better written as

print OUT unpack("H*",$data);
[download]

But that's as may be.

True, but in all fairness I'm new, so I need help identifying what fish I need to fish for ;). At least I'm learning to fish in the Perl pond.	[reply]

I'm not sure what you mean here. The purpose of my post was simpy to provide some documentary clarification for a point made by the Anonymous Monk. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]

Anonymous Monk mentioned unpack, so AnomalousMonk posted the documentation for that function, along with the documentation for pack, so that you could get a better understanding of what they actually do (essentially, elaborating on anonymonk's answer).	[reply]
