The directory stack underlies the functions of these two commands. It is an array of paths stored as an environment variable in the CLI, which can be viewed using the command dirs in Unix or Get-Location -stack in PowerShell. The current working directory is always at the top of the stack.
The > in the third example is a redirection operator, telling the command-line interpreter to send the output of the command not to its own standard output (the screen) but to the named file. This will overwrite the file. Using >> will redirect the output and append it to the file.
The target nickname must be in the same channel as the client issuing the command, and the client must be a channel operator. Normally an IRC server will limit the number of different targets a client can send messages to within a certain time frame to prevent spammers or bots from mass-messaging users on the network, however this command can ...

In computing, redirection is a form of interprocess communication, and is a function common to most command-line interpreters, including the various Unix shells that can redirect standard streams to user-specified locations. The concept of redirection is quite old, dating back to the earliest operating systems (OS).
Example usage of tee: The output of ls -l is redirected to tee which copies them to the file file.txt and to the pager less. The name tee comes from this scheme - it looks like the capital letter T. The tee command is normally used to split the output of a program so that it can be both displayed and saved in a file. The command can be used to ...
[c] In almost all cases, free-to-air. Examples: Channel 8 (Mar del Plata, Argentina), Akita Television, KTVQ. Radio Distributes programming to a network of stations, either owned-and-operated by the network or affiliated and owned by a third party. May have windows in its program lineup for regional programming.
The parentheses in the C shell example are to avoid having the bit-shifting operators confused as I/O redirection operators. In either language, parentheses can always be used to explicitly specify the desired order of evaluation, even if only for clarity. Return values are limited to 8-bit.
