awk
The POSIX Command Language and Utilities standard for awk
(1992)
introduced the following changes into the language:
CONVFMT
for controlling the conversion of numbers
to strings (see Conversion of Strings and Numbers)
In 2012, a number of extensions that had been commonly available for many years were finally added to POSIX. They are:
fflush()
built-in function for flushing buffered output
(see Input/Output Functions)
nextfile
statement
(see The nextfile
Statement)
delete
Statement)
See Common Extensions Summary for a list of common extensions not permitted by the POSIX standard.
