Executing executable file by means of script file
I'm going to assume that, from your question, you would like to run a specific command from a script.

Quite simply, in your script, start with

#!/bin/bash


and below that, add your command name

sflm


Of course, this assumes that you have moved the sflm binary to a /.../bin folder. If you haven't, then

bash /path/to/sflm


This specifies that /path/to/sflm is to be run by bash. Substitute bash with any other shell of your choice.

Finally,

chmod 775 /path/to/script


And ./script to run.
