gawk: Output Summary
5.11 Summary
============
* The 'print' statement prints comma-separated expressions. Each
expression is separated by the value of 'OFS' and terminated by the
value of 'ORS'. 'OFMT' provides the conversion format for numeric
values for the 'print' statement.
* The 'printf' statement provides finer-grained control over output,
with format-control letters for different data types and various
flags that modify the behavior of the format-control letters.
* Output from both 'print' and 'printf' may be redirected to files,
pipes, and coprocesses.
* 'gawk' provides special file names for access to standard input,
output, and error, and for network communications.
* Use 'close()' to close open file, pipe, and coprocess redirections.
For coprocesses, it is possible to close only one direction of the
communications.
* Normally errors with 'print' or 'printf' are fatal. 'gawk' lets
you make output errors be nonfatal either for all files or on a
per-file basis. You must then check for errors after every
relevant output statement.
