Re: Comparing 2 arrays but ignoring certain patterns

in reply to Comparing 2 arrays but ignoring certain patterns

Omit building the hash and try the following grep that uses smart matching:

@newlist = grep !((split /:/)[0] ~~ @removelist), @testlist;

Output:

ctahci
ctsata_1:25:seed

Update:

NetWallah provided excellent fixes for your code, and it generates your desired output. You may still, however, use the above grep that doesn't use a hash.

The smart match operator ( ~~ ) was introduced in perl-5.10, so you'll need perl newer than 5.10 if you want to try it	[reply]
