has

has helps you check presence of various command line tools on path.

How ?

Download the has file. There is no dependency apart from bash itself

$ bash has node npm java git gradle 
✔ node 8.2.1
✔ npm 5.3.0
✔ java 1.8.0
✔ git 2.14.1
✔ gradle 4.0.1

Just download the has script in your path.

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

curl -sL https://raw.githubusercontent.com/kdabir/has/master/has | bash -s git node npm
✔ git 2.14.1
✔ node 8.2.1
✔ npm 5.3.0

And if that's too much of typing everytime, setup an alias

alias has="curl -sL https://raw.githubusercontent.com/kdabir/has/master/has | bash -s"

And uses it

$ has git
✔ git 2.14.1
