Hello,
I have a file F1 with lines f1..fn
and another file F2 with lines of regular expressions e1..em.
I want to delete all lines in F1 which match any of the expression lines
in F2.
(Maybe deleting is too complicated, so I guess I could write the lines
that do *not* match INTO another file and rename/delete the files last.)
I know about for..tokens to process text files.
Problem:
Batch programming does not sup****t functions which could return a
boolean value for "is in file F2".
What can I do to implement this? Set a global variable? Or is there a
more clever approach?
Thank You
Joachim
