Sencha Cmd v3.1.2.342
I made a small change to the sencha shell script to support it being symlinked to a directory already in my path which others might find useful.
In other words the install is in /usr/local/Sencha but /usr/local/bin/sencha is a symlink.

-BASEDIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
+BASEDIR="$( cd "$( dirname $( readlink -m -n "${BASH_SOURCE[0]}" ) )" && pwd )"
