Hi Ralph, Thanks a lot for the info.
I had already seen the movie, the book would have been better ;) Unfortunately I don't have easy access to the prompt since it's embedded. So i can't prompt for help. Fortunately I build U-Boot with buildroot, so i have the source code. It is a big meager, but I ended up grepping the man pages from source: pcregrep -M -r --buffer-size 9000000 "U_BOOT_CMD\([^;]+.*" . > U_BOOT_CMD_HELP.txt Cheers, Jasper On Wed, 9 Sep 2020 at 20:53, Ralph Siemsen <ralph.siem...@linaro.org> wrote: > Hi Jasper, > > On Wed, Sep 09, 2020 at 07:03:58PM +0200, Jasper van Santen wrote: > > > >I am sorry to ask such a basic question, but i really can't find any > >documentation on the commands possible in scripting. > >Documentation of Hush and its commands i can't find. > > The hush shell gives you the ability to do loops/conditionals.
