A command file is a good tool to help you determine what file type of a file. To check for a file type simply do this

file filename

Let say i want to check the file type of command line update-rc.d, i can do this

file `which update-rc.d`

output:

/usr/sbin/update-rc.d: perl script text executable

Uses which to returns the full path of the filename and back quote is to return result to command file.
