|
|
|
```shell

|
> which python
|
|
─────────┬─────────────────
|
|
arg │ python
|
|
path │ /usr/bin/python
|
|
builtin │ No
|
|
─────────┴─────────────────
|

```

```shell
|
|
> which cargo
|
|
─────────┬────────────────────────────
|
|
arg │ cargo
|
|
path │ /home/bob/.cargo/bin/cargo
|
|
builtin │ No
|
|
─────────┴────────────────────────────
|
|
```
|
|
|
|
`which` will identify nushell commands:
|
|
|
|
```shell
|
|
> which ls
|
|
─────────┬──────────────────────────
|
|
arg │ ls
|
|
path │ nushell built-in command
|
|
builtin │ Yes
|
|
─────────┴──────────────────────────
|
|
```
|

```shell

|
|
arg │ which

|
|
|

Passing the `all` flag identifies all instances of a command or binary
|
|

|
```shell
|
|
> which ls --all
|
|
───┬─────┬──────────────────────────┬─────────
|
|
# │ arg │ path │ builtin
|
|
───┼─────┼──────────────────────────┼─────────
|
|
0 │ ls │ nushell built-in command │ Yes
|
|
1 │ ls │ /bin/ls │ No
|
|
───┴─────┴──────────────────────────┴─────────
|
|
```
|
|
|
|
`which` will also identify local binaries
|
|
|
|
```shell
|
|
> touch foo
|
|
> chmod +x foo
|
|
> which ./foo
|
|
─────────┬────────────────────────────────
