two command at once in bash.profile

[keak]

hi there,
I was wondering if it was possible to execute two commands at once and set it as an alias in bash_profile.

I want to have a single command to do
"sudo -H -u user1 bash" and then "cd ~" in one command and have it set as an alias in bash_profile.


I saw something on the internet that went
alias suuser1 ='sudo -H -u user1 bash; cd ~' but that didn't quite work.

Is my only option to write a seperate shell script for this?

function foo  ()
{
	echo foo
	echo foo
}

alias bar=foo

works for me

So... you want to [tt]sudo bash[/tt], then [tt]cd[/tt] to the home directory not in the original shell, but in the shell you just started?

See why a single alias or even a single shell script isn't gonna do anything for you, here?


Are you looking for [tt]sudo -i[/tt]?

What I am trying to do is to do "sudo -H -u user1 bash"
at this point, if I type ls, I will get permission denied since I am still in the previous user's home dir.

Is there a sudo -i option.
my man sodo does not seem to show so...
sudo -V | -h | -L | -l | -v | -k | -K | [-H] [-P] [-S] [-b] [-p prompt]

I guess I will have to write a function as stefanwangner pointed out.

Thanks

Your [tt]sudo[/tt] probably doesn't have the option. Mine doesn't either, but newer versions apparently do.


You didn't understand the main point of my post. I was explaining why you're not going to find what you're looking for.

You can't run an alias (or program or function or shell script or shell-builtin) that does one thing in one shell, then another thing in another, different, separate shell.

Your first command, [tt]sudo bash[/tt], which is run from the original shell, starts a second shell. You can't run a command in that second shell by typing it to the first one.


Instead, you'll need to tell either [tt]sudo[/tt] or [tt]bash[/tt] to run the [tt]cd[/tt] command.

With [tt]sudo[/tt], the [tt]-i[/tt] option is one way to do it. There may be other ways that work with your version of [tt]sudo[/tt].

To do it through [tt]bash[/tt], you might try something like

sudo -H -u user1 bash -c "cd ~; exec bash -l"

That's off the top of my head, and there's probably better way to do it.

Thanks for the input chipperMDW
now I see what you meant.
Yeah I think my sudo is old (does not have -i nor -c).
I am looking around now to see if there is a wrok-around for this as I don't have the prev to install a newer version of sudo.

That [tt]-c[/tt] is meant for [tt]bash[/tt], not for [tt]sudo[/tt]. I think [tt]-c[/tt] existed back in the 70s with the original Bourne shell, so your [tt]bash[/tt] definitely isn't too old to have it.


Did you try that command? It does exactly what you want, as far as I can tell.

If you really did try it and [tt]sudo[/tt] tried to interpret the [tt]-c[/tt] itself, you may need to quote the entire bash command.
