python - Launch Pycharm from command line (terminal)

Question

I want to try out PyCharm for sage mathematics development. Normally I run eclipse to do sage development, but now I want to try it with PyCharm.

To launch eclipse with sage environment variables, in command line I normally do the following:

sage -sh
cd /path/to/eclipse
./eclipse

The first line loads the sage environment variables, the remainder launches eclipse. How can I do the same thing for pyCharm? (note I am using a Mac and Ubuntu for sage development; the commands above are agnostic to both OSes)

1. Link 1 is close to the solution I am looking for, however I cannot find a pyCharm.sh anywhere.
2. Link 2: Jetbrains does not give clear instructions either.

Edit (April 2020): It seems that launcher script creation is now managed in Toolbox App settings. See the Toolbox App announcement for more details.

1. Open Application Pycharm
2. Find tools in menu bar
3. Click Create Command-line Launcher
4. Checking the launcher executable file which has been created in /usr/local/bin/charm
5. Open project or file just type $ charm YOUR_FOLDER_OR_FILE

Maybe this is what you need.
