Installation with sudo

With regard to installing pip, using curl (instead of wget) avoids writing the file to disk.

curl https://bootstrap.pypa.io/get-pip.py | sudo -H python3.6

The -H flag is evidently necessary with sudo in order to prevent errors such as the following when installing pip for an updated python interpreter:

The directory '/home/someuser/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
The directory '/home/someuser/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Installation without sudo

curl https://bootstrap.pypa.io/get-pip.py | python3.6 - --user

This may sometimes give a warning such as:

WARNING: The script wheel is installed in '/home/ubuntu/.local/bin' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

Terminal konumu kısaltma

Bash 4 introduced a new environment variable called PROMPT_DIRTRIM that allows the shortening of paths displayed in its prompts (via w in PS1. I added

PROMPT_DIRTRIM=3

to my ~/.bashrc and whereas Bash used to display this prompt:

[user@host /media/D/Projects/nitdroid/ul/out/target/product/generic/system/framework]$

It now displays

[user@host .../generic/system/framework]$

which is a huge improvement especially when working with deep directory structures.
