Shell script to launch Java app won't execute

Question

I am using debian and xterm.

I have created a file 'run.sh' containing the following:

java -cp bin Main
read -n1 -r ip "Press any key to continue..." key

In Properties window I gave it permission to run as program.

Double clicking the file does nothing. Right click 'Execute' does nothing. Open-with UXTerm does nothing.

If I open a terminal in the same directory and type

java -cp bin Main

then it will run, but the shell script file never works.

What am I doing wrong here?

try launching same script from terminal and see the error message — Jigar Joshi

Your shell script file doesn't seem to have a shebang line,

#!/usr/bin/env bash
java -cp bin Main
read -n1 -r ip "Press any key to continue..." key

and make sure it has a execute permissions

chmod a+x <script_file>

You need to add a shebang line at the top of your file: #!/usr/bin/bash. This tells the operating system that the file is in fact a bash executable rather than a normal file. Alternatively, execute the script by entering bash run.sh from the command line.
