# Basics of the linux shell
|
|
|
|
## Streams
|
|
|
|
The linux shell (this will usually be [`bash`](bash.md)) works using different streams
|
|
|
|
The main three streams that are used on the command line are STDIN (Standard input), STDOUT (Standard output), STDERR (Standard Error)
|
|
|
|
|ID|STREAM|USE|
|
|
|---|:----|:---|
|
|
| 0 | STDIN | Used to send input to the program |
|
|
| 1 | STDOUT | Used to receive output from the program |
|
|
| 2 | STDERR | Used to receive errors from the program |
|
|
|
|
### Standard Input
|
|
|
|
Standard input is how we send input to an application it is also how we interact with the command line shell (Usually [`bash`](/bash.md))
|
|
|
|
Once thing that makes the linux command line so powerfull is the suite of commands that is provided all work using STDIN, STDOUT and STDERR you can pipe information from one stream to another (i.e the STDOUT from one program can be in STDIN to another) |
