If you have GAM7 installed you already have the complete syntax reference on disk, at ~/bin/gam7/GamCommands.txt. Two commands will put any command's full argument list in front of you in a few seconds.
Find the line the command is defined on:
grep -n "print filelist" ~/bin/gam7/GamCommands.txtThen read the block from there — seventy lines is usually enough to cover one command:
sed -n '7729,7800p' ~/bin/gam7/GamCommands.txtThis told me whether print filelist select <folder>
The advantage over the online documentation is that the file matches the version of GAM you actually have installed, so there is no question of reading syntax for a release you are not running. It is also there when you are working on a machine with no browser to hand.
Have a good day!
