is there a tutorial on how to make your own commands for shell scripts... for example, i want to make a command 'camera' that will ask for su password then mount my digital camera (/dev/sda1) to a specific point (/mnt/camera) and another one that will copy files from my computer to my school account using scp, basically transfering this

scp *file name@eminem.cs.colostate.edu:~/public_html

to like this

schoolcp *file

and it would just insert the variable... thanks

I would makea seperate shell script called camera and have it do wht you want camera to do - there (as far as I know) is no actual way to unless you want to do some programming

It should be easy enough to do tho... Look up on Google for bash shel scripting tutorials - there are heaps around (including a very good one at www.tldp.org)

Save as "upload" or something and drop it in your personal bin directory (~/.bin if you have it set up) and make it executable. Call it as upload filename, $1 always means "the first argument to this script" so the arguement you type with replace $1 on the scp command in the script.

As for the other script, I think an expect script would do better than a shell script considering the su part. But on the other hand you could make an alias, that would probably be even better.
Put that in your ~/.bashrc, ~/.bash_profile or something. Or just type it at the prompt. When you type cam you will be asked for the root password and then the camera will be mounted.

I would use
scp $@ name@eminem.cs.colostate.edu:~/public_html
instead to allow copying multiple files ($@ expands to all command line arguments)

Nice, I didn't know that. Thanks.
