ascii - strip all the pure ASCII lines from a file
ascii [-n] [file]
-n Extract the lines containing nonASCII characters
ascii file >outf # Write all the ASCII lines on outf
ascii -n <file >outf
# Write all the nonASCII lines on outf
Sometimes a file contains some nonASCII characters that are in the way.
This program allows the lines containing only ASCII characters to be
grepped from the file. With the -n flag, the nonASCII lines are grepped.
No matter whether the flag is used or not, the program returns an exit
status of true if the file is pure ASCII, and false otherwise.
