 * `-0`: input filenames are seperated by NUL bytes (default: newlines).
+* `-k`: keep going: don't stop when a command failed to execute.
 * `-n`: don't run the commands, just print them.
 * `-v`: print commands before running them.
 * `-I`: replace occurences of *arg* with the argument (default: `{}`).
