How to get exit code from remote machine using sshpass command

Question

I want to list the files on the remote machine using bash script without entering password.

I am using following command to do it

sshpass -p password ssh [email protected]  "ls /usr/local/"

I want to get the exit code from the above command to know my command (ls /usr/local) fails or get passed.

How to do it? Kindly help me

Why are you using sshpass rather than passwordless RSA/DSA keys? — John Kugelman

Can you give us some context for this? Where does the above command fit into a larger script? A bigger picture will help us provide more appropriate answers. — ghoti

There are indeed use cases for sshpass. Also using ls in scripts is perfectly okay for testing or for output. It can well be a placeholder for a more useful command. I'm pretty sure the OP simply asked how to get the return value of ls through to the calling shell when using sshpass. — Pavel Šimerda

For example:

[STEP 101] # sshpass ssh 127.0.0.1 true
[STEP 102] # echo $?
0
[STEP 103] # sshpass ssh 127.0.0.1 false
[STEP 104] # echo $?
1
[STEP 105] # sshpass ssh 127.0.0.1 exit 11
[STEP 106] # echo $?
11
[STEP 107] #

If I understood you clearly, you need not ls output, just only exit code, right?

So, try this:

sshpass -p password ssh [email protected]  "ls /usr/local/ &>/dev/null && echo $? || echo 1"

It will return and print 0 if command passed, print 1 in another case.

Is there way to display error messages when failure?

I don't get output as 1 if ssh password or ssh username or url is wrong.
