Study Notes
- Navigating the terminal with bash requires knowing a few essential commands, such as the PWD command for printing the current working directory.
- The PWD command can be used to see the current working directory and has options to display different information like physical paths or symbolic links.
- Another crucial command for navigating the file system is the cd command, which stands for changing the working directory.
- The cd command allows users to move from one location to another by specifying the path they want to go to.
- Pushd and popd commands work with a stack data structure, allowing users to push directories onto the stack and pop them off, making it easier to navigate between different levels without remembering full paths.
- Pushd adds a directory to the stack, while popd removes the top directory from the stack using a last in, first out operation.
- Pushd and popd commands are particularly useful when navigating between different directories in scripts or when working in various areas of the file system without the need to remember specific paths.
