Re^4: filter the files in a folder on the basis of some variable present in them

Hey Discipulus sorry to bother you once again, but when I run code written by you. I got output:

perl discipulus.pl
checking 'invalid.txt'
        found:'z2=0.7'
checking 'valid.txt'
        found:'some_t2=0.7'

can you please see to it one more time? Yes, I know I need to practice perl a lot and I am going to do it (help me with this)
