File: coreutils.info, Node: yes invocation, Prev: printf invocation, Up: Printing text 15.3 ‘yes’: Print a string until interrupted ============================================ ‘yes’ prints the command line arguments, separated by spaces and followed by a newline, forever until it is killed. If no arguments are given, it prints ‘y’ followed by a newline forever until killed. Upon a write error, ‘yes’ exits with status ‘1’. The only options are a lone ‘--help’ or ‘--version’. To output an argument that begins with ‘-’, precede it with ‘--’, e.g., ‘yes -- --help’. *Note Common options::.
