udfk_test-verify user-defined function key file
udfk_test [-v]file
reports on errors in the file containing user-defined function keys. The file is normally passed to mio(1) with the -u option. mio can also detect an incorrectly formatted file, but its diagnostics are limited, compared to those of udfk_test. When run with the -v option, udfk_test prints the character sequence associated with each mio command, based on file's contents.
