Very simple bash script which compresses javascript files with Google Closure Compiler online service and then creates a single file of them. CompressJS reduces file sizes and saves bandwidth with just one simple command.
Files you want to compress and add to the resulting file should be separated with spaces. The last filename is a build target.
Run next command in terminal:
$ ./compressjs.sh jquery-ui-1.8.16.custom.min.js chat-widget.js target.min.js
Of course you can use wildcards in file names and patterns:
$ ./compressjs.sh scripts/*.js target.min.js
