Return for Dos2UNIX

Hi,
I have to test to see if dos2unix is installed on the machine. Right now I am typing in dos2unix and hitting ctrl C. Is there a better workaround for this. If dos2unix is there is need to print the statement saying its there and vice versa. How can i accomplish this.
thank you in advance

which dos2unix

would give the path to the utility if it is in your search path. That might suffice..
