-This is the default page, edit it as you see fit. To add a new page simply reference it within brackets, e.g.: [SamplePage].
+**cmdok** checks that specified commands are OK. If command is OK than it exists in PATH and can be run. 
+It is a simple, small and portable Bash script. It is useful in software packages that want to check that some commands exist before trying to run them.

-The wiki uses [Markdown](/p/cmdok/wiki/markdown_syntax/) syntax.
+### Example

-[[members limit=20]]
-[[download_button]]
+~~~bash
+$ cmdok gcc
+checking gcc ... OK
+
+$ cmdok install tar gzip ar clang
+checking install ... OK
+checking tar ... OK
+checking gzip ... OK
+checking ar ... OK
+checking clang ... OK
+~~~
+
+**cmdok** retruns '0' on success. It can be used in scripts that check commands before running them. Example:
+~~~bash
+if cmdok -f install; then
+  install ...
+else
+  exit 1
+fi
