Here's a couple of semi-useful scripts I did because I like
playing with shell scripts.
Both are for use under V1.2.
The first uses a combination of the date command and the setdate command
to act as a touch command. The second shows a way to get a kind
of menu selection in a shell script.
The names are important. touch must be called touch, because of
the Execute statement within the script, and menu must be called
menu for the same reason. (and both naturally should live in the
S directory.)
Both scripts show some useful tricks you can use in other scripts.
In particular, touch shown how to parse parameters in a script
file, while menu shows a (possibly) unrecognized ability of AmigaDos
commands (use of the ?)
