The vertical bar symbol "|", also known as a "pipe," is a command used in command-line interfaces to connect two or more commands together. It allows the output of one command to be used as input for another command.
When the "|" symbol is used, the output of the command before the "|" is sent as the input to the command after the "|". This allows for the combination or chaining of commands, in which the output of one command is processed or filtered by another command.
For example, suppose you have a text file called "file.txt" and you want to find all the lines that contain the word "apple" and sort them in alphabetical order. You can achieve this using the following command:
grep "apple" file.txt | sort
In this command, the "grep" command is used to search for lines in "file.txt" that contain the word "apple". The output of the "grep" command, which is the lines containing "apple", is then sent as input to the "sort" command. The "sort" command will arrange those lines in alphabetical order based on their content.
This is just one example of how the "|" command can be used. It is a powerful tool that allows for the combination of different commands to perform complex operations on data.
