How to automount SSHFS volumes with FUSE OS X on Mavericks
I have using Homebrew and its sshfs bundle to mount SSH filesystems on my Mavericks Mac for a while now, it has been solid.

So if you run Homebrew go ahead and try the following to install sshfs: brew install sshfs. Then maybe reboot (?) and once you're back sshfs &lt;username&gt;@&lt;hostname/IP&gt;:&lt;remote-path&gt; &lt;local-path&gt;. You will get a password prompt at this point if you're using that kind of authentication. If you're using SSH keys then probably no prompt.

Update: maybe you should modify your bash script to use nohup. it sounds almost like the process dies after it runs your bash script. checkout nohup on wiki or man nohup.
