I have two files here (file 1 & file 2). I would like to match names from both files (e.g John06/ext, lily099/poli). However I need to print those unmatched data in file 1 format. I have been trying the code below but it is not the result I want. How to print those unmatched data in file 1 format after matching?

file 1

ID alan135/xkr $work(b05bfn00un0c3)/b05bfn00un0c3 ; #<= b05bfn00un0d0 Size:5848.270996

ID John06/ext $work(b05bfn00ld0p7)/b05bfn00ld0p7 ; #<= b05bfn00ld0s0 Size:INFINITY

ID lily099/poli $work(b05bfn00ld0p7)/b05bfn00ld0p7 ; #<= b05bfn00ld0s0 Size:INFINITY

ID sam012/pp $work(b05bfn00ld0p7)/b05bfn00ld0p7 ; #<= b05bfn00ld0s0 Size:INFINITY

ID lily099/poli $wwrk(b05bfn00ld0p8)/b05bfn00ld0p8 ; #<= b05bfn00ld0s0 Size:INFINITY

ID Steve9018 $work(b05bfn00ld0p7)/b05bfn00ld0p7 ; #<= b05bfn00ld0s0 Size:INFINITY

my $cname1 = "$2"; 

if ($cname1 ne $line3) { 

print NL "$cname1\n";

expected result:
