README ====== wall-notify is a simple program which receives all messages written by wall and passes them to a notification program via stdin. It's designed for simplistic desktop environments (like tiling window managers) or GNU Screen/Tmux sessions to notify the user about important messages like reboots. It was inspired by KDE's knotify. wall messages are either directly created by root with the `wall` command or sent by other programs like `reboot`, `shutdown` or other processes like NFS to warn users when the NFS server terminates. wall-notify is licensed under GPL 3 (or later). DEPENDENCIES ------------ - C89 compiler - libutempter or utmpx.h (utmpx.x requires a setgid utmp binary) INSTALLATION ------------ ./configure && make && make check USAGE ----- To dump all wall messages to stdout use: ./src/wall-notify cat All arguments passed to `wall-notify` are used when execing the process, e.g. to replace all spaces with underlines use: ./src/wall-notify sed 's/ /_/g' To display the messages with `xmessage` use: ./src/wall-notify xmessage -file - However this will display '^M' (carriage-return) and other control characters in the message. For a simple wrapper script which removes those, see `contrib/message-helper`: ./src/wall-notify contrib/message.sh xmessage -file - The shell is not used when running the program. BUGS ---- Doesn't work on OpenBSD which has no support for utmpx.h. If you find any bugs not mentioned in this document please report them to with wall-notify in the subject.
