Linux Bashrc Configuration | Original
This bashrc
file configures the Bash shell environment in Linux. It customizes the prompt, sets up aliases, manages proxy settings, and integrates with tools like Git. Below is a breakdown of the key configurations:
1. Basic Settings:
HISTCONTROL=ignoreboth
: Ignores duplicate commands and commands starting with a space in the history.shopt -s histappend
: Appends new history entries to the history file.HISTSIZE=1000
: Sets the number of history entries to keep in memory.HISTFILESIZE=2000
: Sets the maximum size of the history file.shopt -s checkwinsize
: Updates the terminal window size.
2. Color Prompt:
- Configures a colored command prompt if the terminal supports it.
3. Window Title:
- Sets the terminal window title to display the current user, host, and working directory.
4. Directory Colors:
- Enables colored output for
ls
command ifdircolors
is available.
5. Aliases:
alias ll='ls -alF'
: Lists all files with detailed information.alias la='ls -A'
: Lists all files, including hidden ones.alias l='ls -CF'
: Lists files in columns.alias alert='notify-send ...'
: Sends a desktop notification after a command finishes.
6. Bash Aliases File:
- Includes a separate file for custom aliases (
~/.bash_aliases
).
7. Bash Completion:
- Enables bash completion if available.
8. Path Configuration:
export PATH=...
: Adds various directories to thePATH
environment variable, including those for CUDA, Ruby gems, local binaries, and system binaries.
9. Proxy Management:
export GLOBAL_PROXY='127.0.0.1:7890'
: Defines a variable for the proxy server address.function start_proxy { ... }
: Sets theHTTP_PROXY
,HTTPS_PROXY
,http_proxy
,https_proxy
, andALL_PROXY
environment variables to use the specified proxy.function start_proxy_without_prefix { ... }
: Similar tostart_proxy
, but sets the proxy variables without thehttp://
prefix.function stop_proxy { ... }
: Unsets the proxy variables, effectively disabling the proxy.export NO_PROXY="localhost,127.0.0.1,.example.com,::1"
: Specifies hosts that should bypass the proxy.
10. Git Proxy:
- `function start_git_proxy { ... }`: Configures git to use the global proxy for HTTP and HTTPS connections.
- `function stop_git_proxy { ... }`: Unsets the git proxy settings.
11. Default Proxy:
- `start_proxy`: Starts proxy by default.
- `start_git_proxy`: Starts git proxy by default.
12. Python Aliases:
alias python=python3
: Setspython
to usepython3
.alias pip=pip3
: Setspip
to usepip3
.
13. Git Message AI Aliases:
function gpa { ... }
: Creates an aliasgpa
to run a python scriptgitmessageai.py
with the mistral API and allow pull and push.function gca { ... }
: Creates an aliasgca
to run the same script without pushing changes.function gm { ... }
: Creates an aliasgm
to run the same script and only print the commit message.
14. Git Push with Pull and Rebase:
function gpp { ... }
: Attempts to push changes, and if it fails, it tries to pull with rebase and then push again.
15. Pre-Execution Proxy Check:
preexec() { ... }
: This function is executed before every command. It checks if the command is in a list of network-dependent commands. If it is, and if any proxy variables are set, it displays the proxy settings.local network_commands=( ... )
: This array lists commands that are considered network-dependent.display_proxy() { ... }
: This function displays the current proxy settings.
16. Check Proxy Function:
function checkproxy { ... }
: Displays the current HTTP and HTTPS proxy settings, as well as Git proxy settings.
