POPD
pushd and popd are shell commands that together allow the user to revert to a previous working directory via the command line. They use a stack data structure for directory paths. pushd pushes the working directory path onto the stack and changes to the specified directory, and popd pops the most recent item from the stack and changes directory to the popped value. Behavior varies if no argument is passed to pushd. On Unix, the command swaps the top two directories on the stack, which toggles between them. On Windows, the command lists the paths in the stack except for the current one. The commands are widely available as builtin commands in many shells, such as Bash, Command Prompt, PowerShell, C shell, tcsh, 4DOS, Hamilton C shell, KornShell, and FreeCOM. The stack of directory paths can be displayed via the dirs Unix command or Get-Location -stack PowerShell command. The working directory is at the top of the stack. The first Unix shell to provide a directory stack was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Command Prompt
A command-line interface (CLI) is a means of interacting with software via commands each formatted as a line of text. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. For a long time, a CLI was the most common interface for software, but today a graphical user interface (GUI) is more common. Nonetheless, many programs such as operating system and software development utilities still provide CLI. A CLI enables automating programs since commands can be stored in a script file that can be used repeatedly. A script allows its contained commands to be executed as group; as a program; as a command. A CLI is made possible by command-line interpreters or command-line processors, which are programs that execute input commands. Alternatives to a CLI include a GUI (including the desktop metaphor such as Windows), text-based menuing (including DO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
