This somewhat depends on what platform you are on. The most common way to do this is by printing ANSI escape sequences. For a simple example, here's some Python code from the Blender build scripts:
class bcolors:
HEADER = '\033[95m'
OKBLUE = '\033[94m'
OKCYAN = '\033[96m'
OKGREEN = '\033[92m'
WARNING = '\033[93m'
FAIL = '\033[91m'
ENDC = '\033[0m'
BOLD = '\033[1m'
UNDERLINE = '\033[4m'
To use code like this, you can do something like:
print(bcolors.WARNING + "Warning: No active frommets remain. Continue?" + bcolors.ENDC)
Or, with Python 3.6+:
print(f"{bcolors.WARNING}Warning: No active frommets remain. Continue?{bcolors.ENDC}")
This will work on unixes including OS X, Linux and Windows (provided you use ANSICON, or in Windows 10 provided you enable VT100 emulation). There are ANSI codes for setting the color, moving the cursor, and more.
If you are going to get complicated with this (and it sounds like you are if you are writing a game), you should look into the "curses" module, which handles a lot of the complicated parts of this for you. The Python Curses HowTO is a good introduction.
If you are not using extended ASCII (i.e., not on a PC), you are stuck with the ASCII characters below 127, and '#' or '@' is probably your best bet for a block. If you can ensure your terminal is using a IBM extended ASCII character set, you have many more options. Characters 176, 177, 178 and 219 are the "block characters".
Some modern text-based programs, such as "Dwarf Fortress", emulate text mode in a graphical mode, and use images of the classic PC font. You can find some of these bitmaps that you can use on the Dwarf Fortress Wiki see (user-made tilesets).
The Text Mode Demo Contest has more resources for doing graphics in text mode.
I am assuming that you don't have the bin directory. You can do the following:
cd
mkdir bin
sudo ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" ~/bin/subl
ln -s
will create a alias of the subl file in your bin directory and you will be able to run the command.
If this still doesn't work you will have to edit your .bash_profile. You can do it by following commands: (NOTE: For this to work you need to have done the above steps already.)
Open your .bash_profile:
cd // this will get you back to home directory
vim .bash_profile // this will open your .bash_profile file
Edit .bash_profile: press I to get into "insert" mode and add following:
export PATH=$PATH:~/bin
Save and exit. Press Esc to get into command mode:
:wq // saves and close file
exit // exits terminal
Reopen the terminal:
subl --help
That should bring up the help for Sublime Text.

Should be:
Notice I removed the tilde (
~
). Tilde (~
) in Unix refers to your user's home directory, so your source was correct, but the second argument was placing the link in /Users/[your username]/usr/local/bin/ which is not included in $PATH.In your note, you said you tried removing the quotes from the source argument. If you remove the quotes, you need to be sure to escape the space character as follows:
That should work as well.
