Having written the script, you can invoke it by sh
scriptname, or alternately bash
scriptname. (Not recommended is using sh
<scriptname, since this effectively disables
reading from stdin within the script.) Much more convenient is
to make the script itself directly executable by
- Either:
chmod 755 scriptname (gives
everyone execute permission)
- or
chmod +x scriptname (gives
everyone execute permission)
chmod
u+x scriptname (gives only the
script owner execute permission)
In this case, you could try calling the script by
./scriptname.
As a final step, after testing and debugging,
you would likely want to move it to /usr/local/bin (as root, of course),
to make the script available to yourself and all other users as a
system-wide executable. The script could then be invoked by simply
typing scriptname [return]
from the command line.
