friends

How do I know which version of awk using my linux?

My first idea woud be to read the man page. man awk :

Others might accept the --version option, and still others don't provide anything at all.

strings /usr/bin/awk | grep -E "version|awk"
/usr/src/usr.bin/awk/../../contrib/one-true-awk/b.c
?--version
awk %s
version 20110810 (FreeBSD)
weird printf conversion %s
out of memory in awkprintf
out of memory in awksprintf
awkdelete
can't happen: bad conversion %c in format()

might yield some insight, but YMMV...

ALternatively:

strings /usr/bin/awk | grep -E "\<version\>"
?--version
version 20110810 (FreeBSD)

In cases where RudiC's suggestions don't work, you can also try:

what /pathname/to/awk

or:

sccs what /pathname/to/awk

On some systems you might even get something useful from:

file /pathname/to/awk
