a unix shell command-line program
This shell script
It also renames the previously-installed NetBeans-nightly.app to a name that includes its date.
If someone would like to modify this script for Cygwin and/or Linux, I will post those versions as well. (Should be trivial to do.)
Example:
Here’s the get-netbeans-nightly program:
