What command is used to display the current working directory?

The command used to display the current working directory in a Linux environment is "pwd," which stands for "print working directory." When executed, this command outputs the full path to the directory you are currently in, allowing users to easily determine their location within the filesystem hierarchy.

The other options do not fulfill this function. The "cd" command is used to change the current working directory rather than display it. "current" is not a recognized command in standard Linux. "locate" is another command used to find files by searching a database for paths that match given criteria, but it does not provide information about the current directory.
