What is the. bashrc file?

The relevant explanations in the online Help file that you see Using the Man Bash command are as follows:
. bashrc-the individual Per-interactive-shell startup file.

This file mainly preserves some personal personalization settings, such as command aliases, paths, and so on. Here's an example:
# User specific aliases and functions
Path= "/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin"
Lang=zh_cn. GBK
Export PATH LANG

Alias rm= ' Rm-i '
Alias ls= '/bin/ls-f--color=tty--show-control-chars '

The example defines the path, language, command alias (always with the-I parameter when using RM Delete command requires user confirmation, and the LS command lists the file list with color display).
After each modification. BASHRC, use source ~/.BASHRC (or. ~/.BASHRC) can immediately load the modified settings to make it effective.

The. BASHRC is typically called explicitly in the. bash_profile file. When you log in to Linux to start bash, you will first read the ~/.bash_profile file so that the ~/.BASHRC is executed and your personalization will take effect.
