Extensions in the Bell Laboratories `awk'
Brian Kernighan, one of the original designers of Unix `awk', has
made his version available via anonymous `ftp' (Note: Other Freely
Available `awk' Implementations.). This section
describes extensions in his version of `awk' that are not in POSIX
* The `-mf NNN' and `-mr NNN' command line options to set the
maximum number of fields, and the maximum record size, respectively
(Note: Command Line Options.).
* The `fflush' built-in function for flushing buffered output (Note:
Built-in Functions for Input/Output.).
