To dump all wall messages to stdout use:
- ./wall-notify cat
+ ./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:
- ./wall-notify sed 's/ /_/g'
+ ./src/wall-notify sed 's/ /_/g'
To display the messages with `xmessage` use:
- ./wall-notify xmessage -file -
+ ./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.
