## How ?

|

$ bash has node npm java git gradle
|

$ has node npm java git gradle

✔ npm 5.3.0

✔ git 2.14.1
|

✔ gradle 4.0.1
|

|
||||
If everything is good `has` exists with status code `0`. The status code
|
||||
reflects number of commands **not found** on your path.
|

$ has node go javac

✔ node 8.2.1

✔ go 1.8.3
|

✘ javac

And echo the status:

$ echo $?

|

|

## Installing
|
||||
|
||||
Just download the `has` script in your path.

If you are lazy, you can has of the internet as well
|

git clone https://github.com/kdabir/has.git && cd has && make install
|

|

|

If you are lazy, you can run `has` directly off the internet as well:
|
||||
|
||||
curl -sL https://raw.githubusercontent.com/kdabir/has/master/has | bash -s git node npm
