The .bashrc file is a hidden configuration script located in a user's home directory on Unix-like operating systems, including Linux and macOS. Its main purpose is to configure and customize the Bash shell environment for each user[2][5][6].
.bashrc is executed automatically every time a new interactive, non-login Bash shell session is started (such as when you open a new terminal window or tab)[1][2][5].alias ll='ls -alF')[2][4][6].PATH to specify where the shell looks for executable files[2][5].| Feature | Description |
|---|---|
| Hidden File | Named .bashrc, it is hidden by default (use ls -a to view it)[2][3][4]. |
| User-Specific | Each user has their own .bashrc in their home directory (~/.bashrc)[2][6]. |
| Script File | Contains valid Bash commands and can be edited with any text editor[2][3][6]. |
| System-Wide Version | Some systems also have a global /etc/bash.bashrc affecting all users[2]. |
# Add custom directory to PATH
export PATH=$PATH:~/my_scripts
# Alias for listing files
alias ll='ls -alF'
# Custom function
function goto_projects {
cd ~/projects
}
The .bashrc file is essential for anyone who regularly uses the terminal, as it streamlines workflows, enhances productivity, and allows for a highly personalized shell experience[2][4][5]. Editing this file gives users control over their command-line environment every time a new terminal session is started.
