Patch provided by MAINTAINER, Francis GUDIN.
The changes in version 0.8 are:
- When using dtach -A or dtach -c, the master will now wait until the client
attaches before trying to read from the program being executed. This avoids
a race condition when the program prints something and exits before the
client can attach itself.
- Instead of exiting quietly, dtach will now report any errors that occur
while trying to execute the program.
- dtach -n can now be used without a terminal.
- dtach -A will now try to detect and remove stale sockets.
- Removed a Linux-specific escape sequence from the code that restores the
original terminal settings.
- Changed dtach.1 to use \- for the dashes in command line options, and
fix an ambiguous backslash.
- Use non-blocking mode in the master process, and avoid data loss by ensuring
that at least one attaching client succesfully completes a write.
- Fix -e ^<char> to work with lowercase characters.
dtach is a tiny program that emulates the detach feature of screen,
allowing you to run a program in an environment that is protected from
the controlling terminal and attach to it later. dtach does not keep
track of the contents of the screen, and thus works best with programs
that know how to redraw themselves.
