The lack of a more command is causing the help command to fail in the karaf console:

Looks like it is working for you just fine. Could you try this command:

openhab> help shell

And see if shell:more is an available command? or perhaps:

openhab> shell:more --help

I do not have the shell:more command available in karaf. The only pager I have is shell:less. It seems the default pager is set to a command which doesn’t exist in my particular case.

Your more command seems to be aliased to less. Mine is not, for whatever reason. Strange.

I just checked /opt/openhab2/userdata/etc/shell.init.script and the following alias is defined for help:

help = { *:help $args | more } ;

But since I don’t have a more command in my Karaf shell, I changed this to:

help = { *:help $args | less } ;

This has solved the problem of using the help command. The question is…why don’t I have a more command in my Karaf shell (since the Karaf documentation says that command is implemented by default). I seem to be the only one with this problem…

Did you install openhab via the apt repos or manually?

What does your shell.init.script file look like?

Just chiming in that I had the same issue of not having more available. And this fix of editing shell.init.script worked for me. Thanks!

This was in a similar environment. A manual install of 2.3.0-SNAPSHOT Build #1250

Sorry, I should have posted what fixed this for me (of course, once it was fixed, I just moved on…).

I replaced the contents of my shell.init.script with the contents of the same file from the openhab github repo.

They were quite different. My shell.init.script had the default values from the karaf repo and/or documentation. Somehow the OpenHAB upgrade script didn’t touch that file…weird.
