I'm not sure but I think it's because your var CMD is set to a string
"/usr/bin/sudo /bin/su - villin" <---- this is a string not a command

try this:
CMD=`/usr/bin/sudo /bin/su -villin`

Searched here and google and couldn't find a viable solution. Is there a way to transfer a file with curl and have it automatically attempt to resume it if there's an error, broken pipe,...

not proper syntax... the . needs a / after it. Files starting with a . are hidden files. So .B is a legit file name. Filenames can have spaces in them too. So: [SPACE]B is a legit name too, just not...

the dot (period) means "in the current working directory". So ./B means "execute B which is in the current working directory". You can use it with other commands too such as find. find . -type f...

There's a reason you're listed in the credits of my script lol

yea you gotta keep to the if/then or if/then/else...syntax. You need to specify what to do in the event the test (if) is true or false. Human speak: If something evaluates to true or false then do...

Ok so I know the title was probably confusing so here goes: I have a tarball (gzipped) that has a nested directory structure . For example:

my.tar.gz (contents)

The script indeed has terminal output and exit codes for success and non successful termination. When complete it doesnt return the prompt but if i type ls it will ls as if i were at a prompt. I want...

why not use sed? sed 's/Parent=PAC:18235173;PACid=18235173/Parent=PT_0001s00200.1;PACid=18235173/g'

You can do an inline edit to the same file using the -i switch. Or redirect it to another file...

Ok found the caveat: If any of my conditions have an exit 0, the terminal prompt doesn't come back. I can still type commands successfully but i have to manually issue a ^C interrupt to the terminal...

I don't want to use echo because I want the first line to be a comment, and the rest to be values that a script reads from. If the user deletes the commented line like they're not supposed to, i want...

What are my alternatives? Examples?

I can't seem to get sed to allow me to insert text in the first line of an empty file. I have a file.txt that is a 0 byte file. I want sed to insert " fooBar" onto the first line. I've tried a few...

Perfect. There's no thank you button on your post for some reason but thank you. That was the trick

Honestly I don't know, I thought that would work. I'm at the end of my knowledge level on that...Sorry.

Which is sent to a terminal when it closes? SIGKILL? Reason I ask is I have a script I want to run in the background, but want it to run even if the terminal window is closed. Or, I'd like it to...

definitely using a getopts loop. I think piping this to a shell is the way to go for me. Thanks you guys

.Do you want to replace ALL commas in your script to something else? sed -i "s/\,/\|/g" infileChanges all commas to the pipe

Before using sed -i, do it without the -i so you can see what it'll do...

lol damn...too slow

ah ok. I guess I learned something. :-) So did that work for you?

That's what that will do. It will only allow someone who is logged in with a name you've authorized to run the script, to execute the script. If the person logged in is anyone else, it will exit. So,...

You have to use backticks ` to surround the who -m command. Backticks are right next to the number 1 on my laptop's keyboard. Should be for your computer too. Looks like a ' but its not. So:
[ `who...

[ ! `whoami` = "user1" -o "user2" -o "user" ] && echo "You are not authorized to run this script"
This says if you're NOT user1 or user2 or user to echo "You are not authorized to run this script"...

Yea see I personally wouldn't want to be "logging in" to your script with my username and password. Leaves a lot to be desired as far as security. If you allow the user to login to the shell, and...
