Package Jar files into Linux executable files and linuxjar files

Package Jar files into Linux executable files and linuxjar files

Because I don't want to write java-jar jarfile, I want to directly write./jarfile to run the program.

 

#!/bin/bash - #===============================================================================##          FILE: shell_pack.sh# #         USAGE: ./shell_pack.sh # #   DESCRIPTION: # #       OPTIONS: ---#  REQUIREMENTS: ---#          BUGS: ---#         NOTES: ---#        AUTHOR: lwq (28120), scue@vip.qq.com#  ORGANIZATION: #       CREATED: 04/22/2015 02:38:01 PM CST#      REVISION:  ---#===============================================================================#===  FUNCTION  ================================================================#         NAME:  usage#  DESCRIPTION:  Display usage information.#===============================================================================function usage (){        cat <<- EOT  Usage :  $0 [options] -p package -s script file1 file2 file3 ..

Save it to jar_wrapper.sh. Example:

./Jar_wrapper.sh-p/tmp/aaa-j/tmp/test_demo1.jar

Then, chmod + x/tmp/aaa &/tmp/aaa will be able to run the program ~!
