From the command line, pass the list of commands you want to check as arguments to `has`, for example:\n\n```console\n$ has node npm java git gradle\n\u2713 node 22.17.0\n\u2713 npm 11.5.1\n\u2713 java 21.0.7\n\u2713 git 2.50.1\n\u2713 gradle 8.14.2\n```\n\nIf everything is good `has` exits with status code `0`. The exit status code reflects number of commands **not found** on your path.\n\n```console\n$ has node go javac\n\u2713 node 22.17.0\n\u2713 go 1.24.5\n\u2718 javac\n```\n\nAnd echo the status:\n\n```console\n$ echo $?\n1\n```\n\n## Use `has` in scripts\n\n`has` can be used in shell scripts to check presence of tool in very readable way\n\n```bash\nif has node\n    then echo you have what it takes \ud83c\udf89\nfi\n```\n\n**Pro Tip**: the `has` in above command can be replaced with the entire curl command for to ensure portability of script \u2192 `if curl -sL https://git.io/_has | bash -s node then ...`\n\n\n## Installing \ud83d\ude80\n\n`has` is a single bash script that does it all. You can [download](https://raw.githubusercontent.com/kdabir/has/master/has) the script and make it available on your `$PATH`. However, to make it even simpler, just follow *one* of these methods.\n\n### Homebrew (MacOS) \ud83c\udf7a\n\nJust run the following: \n\n```bash\nbrew install kdabir/tap/has\n```\n\n### Cloning the Repo\n\nJust execute the following command in a terminal: it clones `has` repo and installs it into your path.\n\n```bash\ngit clone https://github.com/kdabir/has.git \u0026\u0026 cd has \u0026\u0026 sudo make install\n```\n\nFor a non-root installation:\n\n```bash\ngit clone https://github.com/kdabir/has.git\ncd has\nmake PREFIX=$HOME/.local install\n```\n\nTo update just do a `git fetch` or `make update` followed by the appro",
