in thread correspondence between two arrays

the thing is i want the results with respect to the entries in file1.txt and not the other way around. so if i make the second file as hash, then wont that make the prblem exactly opposite? as for the iteration, i am sorry i think i missed a bracket } there.. sorry for the mistake. Please tell me wat to do.

That is exactly what you get if you hash the second file and iterate over the first one.

When you say you need to "check whether a value exists in something," that almost always means you should put something in a hash, and then check your values against that hash. Since you want to check whether values from file1 exist in file2, you put file2 in a hash (with the part you're checking against as the keys), and then start looping through file1 and checking its values to see if they exist as keys in the hash.
