Re: Removing non-printing (hex codes) from text filesby ww (Bishop)

"Does a file have to exist ...?"
The Zen answer: Can you open a paper bag if you don't have a bag?"
Actually, Perl is somewhat less rigid about that: The answer lies in your terminal: perldoc -f open.
As to your line 26 and title: you seem to have an odd spec: you talk about hex but present octal values....
and those appear to be:
or, if interpreted as hex:
NUL DC1 DC3 DC4 SYN Digit-'7'
Are you sure you've identified the chars you wish to remove correctly?
