Here are some quick tips on how to use the jsobf command line program effectively.
Install the program under one of your search paths so you can just type
jsobf from anywhere in your file system:
$ mv/path/to/jsobf ~/bin/jsobf
Direct output into a destination file, and log any errors in a separate file:
$ jsobf file.js 1>target.js 2>jsobf.log
Pipe source code into jsobf from another program:
$ cat file.js | jsobf
Pipe obfuscated code into another program; here the jsfmt program formats the obfuscated source so you can take a better look at it:
$ cat file.js | jsobf 2>/dev/null | jsfmt
Last but not least – get the js shell from Mozilla, it’s very handy!
