Option 1 - manual download and install on any OS
Note: the above links are not to the files themselves, but rather to pages where you can select a download mirror. Do not use your browser's "Download Link" command on the above links.
Installation instructions are available for the following operating systems:
Installing the platform-specific package
Once you've downloaded the Mac OS X package, open jEdit.dmg. When the jEdit drive image appears on your desktop, copy the jEdit folder on it to your Applications folder (or wherever you'd like install it).
Simply run the jEdit application in the jEdit folder, and code away...
Beware: From 10.8 on your Mac will tell you that jEdit is damaged and you should move it to the trash. This is not true though. This is a new security feature called Gatekeeper that only allows apps from App Store or signed by a certificate issued by Apple for 100 USD per year. To allow jEdit to run, either lower your security settings in "System Preferences -> Security" and allow all apps to run, or Ctrl+click or right-click jEdit.app and choose "Open". As soon as jEdit was run once, Mac OS forgets about its downloaded state and allows it to run normally.
Using the Java-based installer
To start the java installer for jEdit, enter the following in Terminal:
cd directory where you downloaded the JAR file java -jar filename.jar
For example, if you downloaded jedit40install.jar into ~/Documents, you would enter:
cd ~/Documents java -jar jedit40install.jar
If for whatever reason you want to start the installer in text-only mode, specify text as the last parameter on the command line. In text only mode, the installer will not display it's GUI, and instead it will ask questions in the terminal window.
Once jEdit is installed, type the following in Terminal to start jEdit:
java -jar /where you installed jEdit/jedit.jar
For example, if you installed jEdit in /Applications/jEdit, you would enter:
java -jar /Applications/jEdit/jedit.jar
Option 2 - easy install on some flavors of *nix
