Because I wanted to display the Git branch in the prompt, I changed PS1 (The primary prompt string) in ~/.bashrc based on Customize the prompt to display the git branch, so this is a memorandum.

After setting the above,

It became like this.

Memorandum

According to 2.5. Bash Prompt Escape Sequences, it is as follows.

• \h => Hostname
• \u => Username
• \w => Directory (full path)
• \W => Directory
• \t => Time (24-hour format)
• \T => Time (12-hour format)
• \@ => AM / PM
• \d => Date
• \D => Date and time
• \# => Command number
• \! => History number
• \n => Newline

As for the display,

1[<Command number>(<History number>)] <Time HH:MM:SS> <user> at <directory> [<branch>]

It becomes like this.

In the <branch> part, parse_git_branch is called, and inside it, the result of git branch --no-color is replaced with sed, and errors (2) are discarded to /dev/null.

Also, as mentioned in the article above, the following variables can be used for color settings:

1local  BLUE="\[\e[1;34m\]"
2local  RED="\[\e[1;31m\]"
3local  GREEN="\[\e[1;32m\]"
4local  WHITE="\[\e[00m\]"
5local  GRAY="\[\e[1;37m\]"

By the way

It seems that PS2 (The secondary prompt string) can also be set, but it's troublesome so I'll leave it alone.
