I don’t use shell scripts too often and had a brain dead moment on how to execute a shell script.
So, for the dummies :-), here’s a summary so next time I forget I can quickly look at my posts:
For Creating Shell programs
# vi filename.sh (vi is one of many text editors for linux systems)
For Running Shell Programs
# sh filename.sh
# chmod 744 filename.sh (you need to change the permission so you, the owner, can execute the script)
