filepaths

Number the non-blank output lines, starting at 1

Display non-printing characters (see the -v option), and display a dollar sign (‘$’) at the end of each line

Set an exclusive advisory lock on the standard output file descriptor.  This lock is set using fcntl(2) with the F_SETLKW command. If the output file is already locked, cat will block until the lock is acquired

Squeeze multiple adjacent empty lines, causing the output to be single spaced

Display non-printing characters (see the -v option), and display tab characters as ‘^I’

Display non-printing characters so they are visible.  Control characters print as ‘^X’ for control-X; the delete character (octal 0177) prints as ‘^?’.  Non-ASCII characters (with the high bit set) are printed as ‘M-’ (for meta) followed by the character for the low 7 bits
