Tutorial: FreeBSD Ports

FreeBSD port manual

Use pkg_info to list all installed packages:

pkg_info | less

To delete or uninstall packages / apps use pkg_delete command:

pkg_delete pkgname
pkg_delete screen-4.0.3_6
pkg_delete 'screen*'

2nd one will delete package called screen-4.0.3_6 and 3rd command will delete a screen package using wild card.

Also, you can uninstall the same using ports system. For e.g. to delete screen port, enter:

cd /usr/ports/sysutils/screen
make deinstall

To create code blocks or other preformatted text, indent by four spaces:

    This will be displayed in a monospaced font. The first four 
    spaces will be stripped off, but all other whitespace
    will be preserved.
    Markdown is turned off in code blocks:
     [This is not a link](http://example.com)

To create not a block, but an inline code span, use backticks:

Here is some inline `code`.
