Programming :: Perl - Store And Access An Array In A Hash Of Hashes?
Jul 7, 2010I am in need of some syntax help. I'm trying to figure out how to store and retrieve an array out of a hash of hashes. For this example, I'm trying to access the city list for a particular state for a particular country. I understand I could do a join and split on the hash key to combine Country and State, but trying to keep things separated.The code I have gets in all the information for the Countries, and states, and gets the list of cities together, no problem. I store all the city names in an array, then make an anonymous pointer to the array for the hash, like this - $MY_CITIES{$COUNTRY}{$STATE} = [@CITIES]I believe that syntax is correct, or is it? What I'd like to do is I need to cycle through every hash to find if a city exists or not. If it exists in 3 states, then it should print 3 times. Here is the code block to search -
Code:
for $COUNTRY (@LIST_OF_COUNTRIES) {
for $STATE ( keys %MY_CITIES{$COUNTRY){$STATE} ) {

View 20 Replies View RelatedGeneral :: Where Does ITunes Store Its Stuff - Copy Its Data Store To An External Drive
Dec 8, 2009I have two students whose windows laptops are riddled with malware and not working properly. They want me to help them install Linux (which we use in school), but they are concerned about their iTunes.
Having avoided iPods as "defective by design", I know nothing about iTunes whatsoever. However I remember reading about DRM locking and such problems that have me concerned that I won't be able to do it.
Where does iTunes store its stuff?
Can I copy its data store to an external drive, and then into a linux home?
Then will it work on wine, or can another manager (rhythmbox etc) access the itunes data?
Alternatively, if I partition the drive and install linux, can rythmbox/wine/something access itunes data on the win partition?
Supposing they are buying music through iTunes, what will happen to that account?
Finally, one of them has an iphone. Does that work with linux?
Ironic that an apple application is blocking migration away from windows.

Programming :: Receive Command Output And Store It To A Variable?
Apr 3, 2010Suppose I want to account number of files beginning with abc , I can use "ls 'abc* | grep abc | wc -l", this will return me a number.
I want to store this number in a variable, say var1, so I tried
1. "ls 'abc* | grep abc | wc -l |read var1", but this didn't work as var1 has no value somehow.
2. var1='ls 'abc* | grep abc | wc -l', this just assign the entire string "ls 'abc* | grep abc | wc -l" to var1, which is not I wanted.
I don't want to store the value to a temporary file and then read the value from that file. I think there should be a direct way to get the value, but don't know how. I know in tcsh, one can just use set var1='ls 'abc* | grep abc | wc -l', but it also doesn't work in bash. Can anyone give any clue about this?

What should happen if both click "add to cart" at (more or less) the same time?hould the last Product X get put "on hold" for one of the customers, and then decremented once the sale is complete? Or should the database decrement the product count, and then increment it if the sale doesn't go through successfully?Is it still possible for both to add it to their cart? Are there any mysql features I can use to ensure both cannot purchase the last product?
