script add -T fmt to print time-stamps

2022-11-02T09:44:46Z

script -r is useful for recording time-stamps of when output happened. With -T, rather than playback the script in real-time we simply print the time-stamps to show when the output happened. This is very useful for example, for analyzing boot time activity. If the fmt provided contains no % characters the default %n@ %s [%Y-%m-%d %T] is used, which lends itself to analysis by tools as well as humans. Sponsored by: Juniper Networks, Inc.

Have script accept and ignore -e for Linux compat

2020-09-01T16:11:23Z

In the util-linux version of script, it will always exit with succes. Except when run with -e, in which case it will have the exit value of the child. BSD Script already uses the child's exit value for its exit value. Some config and other helper scripts depend on being able to specify -e. Accept it for compatibility since we'll already to the right thing, but otherwise we ignore it.

script: Minor cleanups.

- Instead of using isatty() to decide whether to call tcgetattr(), just call tcgetattr() directly, since that's all that isatty() does anyway. - Simplify error handling in termset(). Check for errno != ENOTTY from tcgetattr() to handle errors that may be raised while running script(1) under a debugger. PR: 248377 Submitted by: Soumendra Ganguly MFC after: 1 week
