Success! Looks like we've fixed this one. According to our records the fix was applied for
CMD-Installer on Os X overwrites .profile
OsX has two configuration files for bash/sh (~/.profile and ~/.bash_profile). ~/.profile is used for bash and shell. If ~/.bash_profile exists, it will be used for bash but the content of ~/.profile will be ignored!
Your installer of extjs-cmd writes its path-environments into ~/.profile. Thats ok. But it also writes into ~/.bash_profile, even if it not exists! That's not a good idea, because if a user has stored the bash- and sh-configuration in his ~/.profile, the existence of the new ~/.bash_profile will make his bash configuration to be ignored.
So please change your installation routine, that it only makes changes to ~/.bash_profile, if it already exists!
It's the same in Version 220.127.116.11, 18.104.22.168 and 22.214.171.124.
Thanks for the report! I have opened a improvement request in our bug tracker.
