How to list all the shell keywords?

Question

$ type if
if is a shell keyword

I don't know the other shell keywords.

Is there any command to list all the bash shell keywords.?

Note: help -m displays both shell builtins and shell keywords.

I am glad to share these two links which are related and helpful: visit this & this — Pandya, Aug 20 '14 at 11:12

For this exists that shell builtin command called compgen which most certainly you did not notice it when you run help -m.

$ compgen -k
if
then
else
elif
fi
case
esac
for
select
while
until
do
done
in
function
time
{
}
!
[[
]]
coproc

See help -m compgen for more info about compgen.

time and coproc are implemented as keywords but they feel more like regular commands when you're writing Bash. – Apr 16 '23 at 11:44

Idea taken from here:

In bash, to list all keywords, first run the following command in terminal:
```
complete -A keyword :
```
Then type at the prompter: :SpaceTabTab.

Works very well for me:

!         {         coproc    elif      fi        if        then      while     
[[        }         do        else      for       in        time      
]]        case      done      esac      function  select    until
