    perl -ni -e 'print unless /sample/' *.*

    This WILL modify all files in the directory. Use with caution.

      To OP: do perldoc perlrun for the explaination of the -i switch including how to have it make backup copies for you.
      Also, you may want * instead of *.* for _all_ (including extension-less ones) (though note that on linux that won't get hidden files)
