Until this thread I didn't have concept of "stream editor", much less

I had heard of "AWK", but had an image of it being a regex parser.
Awk is easy to learn because it is a minimal language. It can do
anything sed can do and much more. I am always surprised that so many
people opt to build long commands with cut/sed instead of using awk.
FWIW, I use mawk because it is orders of magnitude faster than gawk.

I'd like to learn some awk having found it handy once.
apt says mawk is installed
in /usr/bin I have
lrwxrwxrwx 1 root root 21 Apr 2 22:29 awk ->
/etc/alternatives/awk
-rwxr-xr-x 1 root root 658072 Jan 25 12:55 gawk
-rwxr-xr-x 1 root root 3189 Jan 25 12:55 igawk
-rwxr-xr-x 1 root root 121976 Mar 23 2012 mawk
lrwxrwxrwx 1 root root 22 Apr 2 22:29 nawk ->
/etc/alternatives/nawk
"awk" returns options for gawk and "mawk does nothing ( back to prompt)
In /etc/alternatives there is
awk
awk.1.gz
nawk
nawk.1.gz
how to run mawk ?
