Hi all,

I have a script that I need to write that will clean up an /etc/hosts file which has lines of the format
IPADDRESS alias1 alias2 alias5
IPADDRESS2 alias3 alias4
IPADDRESS2 alias3 alias5
IPADDRESS2 alias3 alias5

[download]
for example and I need to rewrite it using a perl script to look like 
IPADDRESS alias1 alias2 alias5
IPADDRESS2 alias3 alias4 alias5

[download]
Right now I have code to read the file line by line, and split that line. This new array of each line is what I need to work with.

I need to create a 
@masterarray

[download]
that will contain an array of arrays for example, my final masterarray should be 
masterarray[0] = [ IPADDRESS, alias1, alias2, alias5]
masterarray[1] = [ IPADDRESS2, alias3, alias4, alias5]

[download]
Is this possible.

My code when looping through each line of the file was originally going to first check if the first field in masterarray[0], masterarray[1], masterarray[x] and so on, was the same as the first part of my linearray (gotten from split) but I can't seem to read IPADDRESS out of masterarray[0] = [ IPADDRESS, alias1, alias2, alias5]

How do i read it... Can I do masterarray[0, 0] to read it? and also how can I add an extra alias to masterarray [0] for example...like alias8, can't I just 

push (masterarray[0] , alias8)

I get lots of errors when trying to do what I want but I am only a starter in Perl, hopefully one of you can help me out even a little bit!!

Thanks alot guys!
Mark
