windows - Shell says find: missing argument to `-exec' and no alternatives working -

a backup program used made duplicates of whole bunch of files throughout computer because of setting i've since changed.

when backup program made copy, renamed old 1 original1.thefilename.extension. i'm trying automatically delete of these unnecessary files simple shell command.

 find -type f -name 'original1*' -exec rm {} \; 

however, when try run get

find: missing argument `-exec' 

i've looked on web solution. i've found suggestions should try exec rm +, -exec rm {} +, -exec rm {} \;, -exec rm + etc. none of them work. using windows 8.1

i appreciate help!

in windows command shell, don't need escape semicolon.

find -type f -name 'original1*' -exec rm {} ; 

your version of command should work in bash shell (like cygwin).

it's interesting gnu find execute, because on windows 8.1 machine, microsoft's find.
