How can I find my awk version?

Solution 1:

In this case, man awk shows us:

-W version

mawk writes its version and copyright to stdout and compiled limits to stderr and exits 0.

In my case,

$ awk -W version
mawk 1.3.3 Nov 1996, Copyright (C) Michael D. Brennan

compiled limits:
max NF             32767
sprintf buffer      2040

Solution 2:

I try to be more general.

awk -Wversion 2>/dev/null || awk --version

works whether awk invokes mawk, gawk or original-awk available for Debian/Ubuntu Linux. Note that -W and version have to be concatenated so that original-awk does not think version is a program. In Ubuntu Linux you can use sudo update-alternatives --config awk to see and to choose the implementation that is invoked by the command awk.
