I am running a script from remote machine via ssh:
ssh 'some_cmd;my_script'
Now, I want to store exit status of shell script on my local machine. How can I do it?

1Could you explain some more details? The command is started from remote and running on local?rpy– rpy2016-06-08 11:35:36 +00:00Commented Jun 8, 2016 at 11:35

Assuming nothing goes wrong with ssh itself, its exit status is the exit status of the last command executed on the remote host. (If something does go wrong, its exit status is 255.)
$ ssh remotehost exit 13
$ echo $?
13

Formally, to "store" the exit status we should assign it to a variable:
ssh remotehost 'do something' ; retcode=$? and it's "stored" in $retcode

I am not sure where the author got that list; it's not in the man page on the machines I've checked. Part of the problem is that the exit status is ambiguous in this situation: did
ssh itself have a problem, or did the program that ssh ran have one of those exit statuses?

Indeed ... this just doesn't cater well for the corner case where the remote exit code equals
255 .... other than that a great answer :)

This is not true for the ssh client coming with FreeBSD 11.1.

This did not work for me on macOS 12.6.2 with SSH version:
ssh -V: OpenSSH_8.6p1, LibreSSL 3.3.6. |
I had same problem. I don't think the previous answers will work (at least, they did not work for me).
This is what worked for me: I ran my command and displayed the exit code and captured it in a variable.
Ensure you protect the $? sign with the escape sequence, \:
# retcode=$(ssh [email protected] "grep -q test /etc/passwd ; echo \$? " 2>/dev/null)
# echo $retcode
# 1
