Chuck,
The "backup" script is a program. BASH only looks for programs which are in
your PATH environment variable (e.g., /bin;/sbin;/usr/bin/;/usr/local/bin...
etc.) unless you specify the path to the executable.
Now you can run your backup script in two ways ('$' means normal user BASH
prompt):
$ /chuck/backup
or
$ cd /chuck/
$ ./backup # this means you tell the interpreter to look in the current
directory not in the PATH
But both those options involve typing, and I hate typing (well, excessive
typing, that is)!
I would recommend either of the following:
1. Create a subdirectory within /chuck called /bin and then add that to your
path by modifying your .bashrc, or
2. Add an alias in your .bashrc which
points to /chuck/backup
Just open your ~/.bashrc file in any text editor and you can find both the
list of aliases (towards the top) and the PATH variable (at the bottom). The
above changes should be self-explanatory.
I prefer the first alternative since it inclines you towards sticking all
executable scripts in one directory, instead of having them clutter up your
/chuck/ directory. As a general rule, put all the stuff that belongs together,
like maintenance scripts in its own directory.
Hope that helps.
