The `x' command prompts the user to enter a key used for - encrypting/ decrypting subsequent reads and writes. If only a newline - is entered as the key, then encryption is disabled. Otherwise, a key - is read in the same manner as a password entry. The key remains in - effect until encryption is disabled. For more information on the - encryption algorithm, see the bdes(1) man page. Encryption/decryption - should be fully compatible with SunOS des(1). - -3) The POSIX interactive global commands `G' and `V' are extended to +2) The POSIX interactive global commands `G' and `V' are extended to support multiple commands, including `a', `i' and `c'. The command format is the same as for the global commands `g' and `v', i.e., one command per line with each line, except for the last, ending in a backslash (\). -4) An extension to the POSIX file commands `E', `e', `r', `W' and `w' is +3) An extension to the POSIX file commands `E', `e', `r', `W' and `w' is that <file> arguments are processed for backslash escapes, i.e., any character preceded by a backslash is interpreted literally. If the first unescaped character of a <file> argument is a bang (!), then the rest of the line is interpreted as a shell command, and no escape processing is performed by ed. -5) For SunOS ed(1) compatibility, ed runs in restricted mode if invoked +4) For SunOS ed(1) compatibility, ed runs in restricted mode if invoked as red. This limits editing of files in the local directory only and prohibits shell commands. |
