Shell Configs

Below is my current bash profile (.bashrc).

Leo's .bashrc

Details

ls

The command:

ls --color=always -F -h

Flags:

--color[=auto]

Ensures that the output is colorized only to stdout. We do not want colors to go through pipes. The 'auto' value is implied as it is the default option.

-F

Prints a forward slash on directories.

-h

Prints sizes in human readable form

grep

The command:

grep --color=always --line-buffered

Flags:

--color=always

Ensures output is colored even if not going to stdout. Makes it nice when piping to more or less.

--line-buffered

As I usually deal with lines of texts, this makes piping multiple greps together work properly.
