# enter
This command creates a new shell and begin at this path.
## Examples
```shell
/home/foobar> cat user.json
{
"Name": "Peter",
"Age": 30,
"Telephone": 88204828,
"Country": "Singapore"
}
/home/foobar> enter user.json
/> ls

Peter │ 30 │ 88204828 │ Singapore
━━━━━━━┷━━━━━┷━━━━━━━━━━━┷━━━━━━━━━━━
/> exit
/home/foobar>
```
It also provides the ability to work with multiple directories at the same time. This command will allow you to create a new "shell" and enter it at the specified path. You can toggle between this new shell and the original shell with the `p` (for previous) and `n` (for next), allowing you to navigate around a ring buffer of shells. Once you're done with a shell, you can `exit` it and remove it from the ring buffer.
```shell
/> enter /tmp
/tmp> enter /usr
/usr> enter /bin
/bin> enter /opt
/opt> p
/bin> p
/usr> p
/tmp> p
/> n
/tmp>
```
