Since you are using double quotes, your two command substitutions are being executed on your local computer. Try single quotes
== is not syntactically correct. a single = should be used
The if statement with the exit commands is reproducing the exact return codes that the test command would produce anyway, so you can just leave it out.
it is best to quote both sides of a string comparison in a test statement
Still consider using $(...) instead of `...` (unless you are using a classic Bourne shell). It saves you quoting troubles..
Combining all this into one, try something like:
You can add 2>/dev/null is you want to suppress messages..

Hello all,
I have a relatively simple script I wrote to generate a count of errors broken down. What I would like to do is execute this script from another server so that I don't actually have to log in to the server to run the check.
The script on what we'll call "Server A" is:

the ssh calling convention:

If I put commands in the section, ssh will execute them immediately after logging in and return to local shell. I want to stay in the remote shell after executing these commands. How can I achieve this?
Thanks for all. (1 Reply)

bup-on
bup-on(1) General Commands Manual bup-on(1)NAME
bup-on - run a bup server locally and client remotely
SYNOPSIS
bup on <hostname> index ...
bup on <hostname> save ...
bup on <hostname> split ...
DESCRIPTION
bup on runs the given bup command on the given host using ssh. It runs a bup server on the local machine, so that commands like bup save
on the remote machine can back up to the local machine. (You don't need to provide a --remote option to bup save in order for this to
work.)
See bup-index(1), bup-save(1), and so on for details of how each subcommand works.
This 'reverse mode' operation is useful when the machine being backed up isn't supposed to be able to ssh into the backup server. For
example, your backup server can be hidden behind a one-way firewall on a private or dynamic IP address; using an ssh key, it can be autho-
rized to ssh into each of your important machines. After connecting to each destination machine, it initiates a backup, receiving the
resulting data and storing in its local repository.
For example, if you run several virtual private Linux machines on a remote hosting provider, you could back them up to a local (much less
expensive) computer in your basement.
EXAMPLES
# First index the files on the remote server
$ bup on myserver index -vux /etc
bup server: reading from stdin.
Indexing: 2465, done.
bup: merging indexes (186668/186668), done.
bup server: done
# Now save the files from the remote server to the
# local $BUP_DIR
$ bup on myserver save -n myserver-backup /etc
bup server: reading from stdin.
bup server: command: 'list-indexes'
PackIdxList: using 7 indexes.
Saving: 100.00% (241/241k, 648/648 files), done.
bup server: received 55 objects.
Indexing objects: 100% (55/55), done.
bup server: command: 'quit'
bup server: done
# Now we can look at the resulting repo on the local
# machine
$ bup ftp 'cat /myserver-backup/latest/etc/passwd'
