I am trying to rename the last _ with a , but not sure how to do that.
Here is what I have so far- 


my @flist = qw'

1st-device-CA_Eth.0/1

2nd-device-TX_Gig.1/1

'; 


print "@flist\n"; 


for my $file (@flist) { 


    $file =~ s{\_[^_]+$}{, }; 

    print "$file\n"; 

}

Output: 
1st-device-CA_Eth.0/1 

2nd-device-TX_Gig.1/1
 


1st-device-CA, 

2nd-device-TX,

Now, how do I get the rest of the info back after that (,)? Please help.
