UNIX for Beginners Questions & Answers

Hey Guys and Gals, Im a complete Noob to Unix. But recently have started working on a unix system for my PET/CT scanner. My scanner comes with a MOD drive for backup. I would like to back up to USB (its alot cheaper). But the only way to do so is by manually enterin the unix commands. Id like to write a shell script to back up the files. I have tried to get one going with a prompt, but i keep getting errors. Think you guys can help me out? here are oics of what i have written and pics of the code from the manufacturer.

Getting what errors?

If you can copy/paste text instead of posting screenshots that would be better.

The code you show is missing a fi. if/else statements in bash work like:

Code:

if [ statement ]
then
        something
else
        something
fi

ah ok. damn i feel dumb. does the rest of the code look ok so far? I cant copy and paste. That system doesnt have internet access. plus the other code is written in the manual. do i just enter the rest of the code underneath the mkdir line?

so, added in the fi, then when i run the script im getting !/bin/bash not found, my echo commands and then -r: is not an identifier.

It should be #!/bin/bash, not !#/bin/bash.

Ok, out of the office for the day, will check it tomorrow.

An embedded device might not actually have /bin/bash, only a more basic /bin/sh.

But you can try "which bash" or "which ksh" or "which sh"
bash would be best if you have it.
