try on your machine
The command echo "hello" | rev
is a combination of two commands separated by the pipe symbol |
.
-
echo "hello"
- Theecho
command is used to display text on the terminal. In this case, it will display the word "hello". -
rev
- Therev
command is used to reverse the order of characters in a given input. When used after the pipe symbol|
, it takes the output from the previous command (echo "hello"
) as input and reverses it.
So, when you execute the command echo "hello" | rev
, it will display the reversed text "olleh" on the terminal.
