Command validation tool

### Description

**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.


### Example

~~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
~~


### Usage

  -n             disable printing any status
  -f             print status only on fail
