in reply to Re: delete FF's from a file
in thread delete FF's from a file

so i can open with filehandle "infile" without "$"?
yes, it is a dump from hardware, but i guess you could call it plain text as it can be opened in notepad but has wild characters.
i tried many different variations of $file =~ and nothing would work out.
i am fixing to read up on the link that was posted earlier.
thanks for all the help

    FWIW, you should binmode if you want to treat your binary files as binary ( no newline translation )

    with open it would be  open my($infile), '<:raw', ... or die ...

    While you're in a learning mood, get a free copy of Modern Perl book, a loose description of how experienced and effective Perl 5 programmers work....You can learn this too.</b.

      yes yes, i did use binmode. thanks for the tips as well :)

    You CAN but there are good some very good reasons not to.

    You will notice from the last link above the "Modern Perl", Recommended by Anonymous Monk below, does not use it.

    At the end of the day its a choice that you make but I disagree with igelkott on this.

    To differentiate you could always call it $input_file_handle or similar.

      filehandle "infile" without "$"

      I don't have an evidence to support my claim of "usually" but maybe that's not relevant anyway. Of course it's possible to use and I didn't mean to imply that it was wrong. There were just so many things that looked "odd" to me.

        Yup! I see what you mean. :-)
