Solved Scripting - How do you store your credentials and call them later?

When running

#!/bin/sh

read -s -p "Enter a wheel username: " USER
read -s -p "Enter a password for wheel: " PASS

# Setting (office) offname variable
read -p 'What office are you in?: ' offname

# Setting (computer username variable) compuser variable
read -p 'Enter this computers username (SAMAccountName) IE jdoe: ' compuser

# Setting the asset tag (tagnumber) variable
read -p 'Enter this computers asset tag: ' tagnumber

echo $PASS | sudo -S -U $USER -l scutil --set HostName $offname$compuser && scutil --set ComputerName $compuser$tagnumber && scutil --set LocalHostName $offname$compuser$tagnumber

I'm met with

Enter a wheel user Enter a password for wheel what office are you in
enter this computers user. . .
enter this computers tag

And that I have to use -l with -U (that is lower case L).

sudo: the `-U' option may only be used with the `-l' option
usage: sudo -h | -K | -k | -V
usage: sudo -v [-AknS] [-g group] [-h host] [-p prompt] [-u user]
usage: sudo -l [-AknS] [-g group] [-h host] [-p prompt] [-U user] [-u user] [command]
usage: sudo [-AbEHknPS] [-C num] [-g group] [-h host] [-p prompt] [-u user] [VAR=value] [-i|-s] [<command>]
usage: sudo -e [-AknS] [-C num] [-g group] [-h host] [-p prompt] [-u user] file ...

Are you doing:

sudo myscript.sh ? Or are you just running the script and letting it call sudo?

Also... What do you have to use -U $USER?

[DustinB3403]

This is the entire portion of the script I'm just testing with (so for the moment it is it's own script).

#!/bin/sh

read -s -p "Enter a wheel username: " USER
read -s -p "Enter a password for wheel: " PASS

# Setting (office) offname variable
read -p 'What office are you in?: ' offname

# Setting (computer username variable) compuser variable
read -p 'Enter this computers username (SAMAccountName) IE jdoe: ' compuser

# Setting the asset tag (tagnumber) variable
read -p 'Enter this computers asset tag: ' tagnumber

echo $PASS | sudo -S -U $USER $PASS scutil --set HostName $offname$compuser && sudo -S -U $USER scutil --set ComputerName $compuser$tagnumber && sudo -S -U $USER scutil --set LocalHostName $offname$compuser$tagnumber

The script is run from a local wheel user so to run it, first I go su wheel-user (because our users by default aren't wheel users and thus need to jump to one) and then call that script.

Sorry, Missed that... I meant to say WHY do you have to use -U $USER ?

sudo rename.sh doesn't work?

Because you need to elevate to root.

@dafyre said in Scripting - How do you store your credentials and call them later?:

It does, but you are prompted to enter a username and password 3 times to make the edits. It's easy to fill-in but annoying to have to do repeatedly.

Hence my attempt at scripting the responses to the prompt windows (example below) Imagine having to type creds 3 times, for 100+ machines.

Also you said to do this, not I.

[DustinB3403]

Woot got it!

[dafyre]

Try this script...

#!/bin/sh

# Setting (office) offname variable
read -p 'What office are you in?: ' offname

# Setting (computer username variable) compuser variable
read -p 'Enter this computers username (SAMAccountName) IE jdoe: ' compuser

# Setting the asset tag (tagnumber) variable
read -p 'Enter this computers asset tag: ' tagnumber

sudo scutil --set HostName $offname$compuser
sudo scutil --set ComputerName $compuser$tagnumber
sudo scutil --set LocalHostName $offname$compuser$tagnumber

Then just run the script with ... sudo ./myscript.sh

You have to enter your password once at the beginning.

@dafyre thanks for helping out there, it was almost there the sudo -S bit was all it needed, but for some odd flipping reason it recommends using -U flag as well which is weird.

But at least it works, now to fold this into the larger script and see how it all works.

I'll be over here in the corner with my hard hat on, watching for nuclear fallout, lol.

Glad you got it going!

atching for nuclear fallout, lol.

I've already made a backup of the master script before edits.

[DustinB3403]

I think my header really sells it.

[DustinB3403]

I'm of course just kidding, lord knows I'd actually get dragged to court with a disclaimer like this. . .

Time to find the GNU license and insert that. . .

[IRJ]

I'm glad you found a solution, but have you considered ansible for tasks like this?

Have you consider our lord and savor jesus christ?

FFS man...

Of course I have I just don't understand it as all of their documentation is god awful and I'd have to take numerous pounds of coke up the backdoor to understand what the hell I'm supposed to do.

On a positive note, if you want to jump on a skype call some time or another I'd be happy to learn if you're willing to teach.

I don't know what you're on. It's some of the better documentation. I'd be interested to see what specific parts you are referencing.
