Answer

Sorry but cant reach the server from home. (Problem on gateway) Will you please cut-and-paste a copy of your program on the Wiki.

:-) Henrik

Tiedote

It's made in WIKI on the name "PINGUIN" at the search... Thanks. ILja

trillex/rune

I got major issues with the "write" program. It works perfectly fine when done in a standard terminal (echo "Ping failed" | write trillex) but when doing this in the script, it gets stuck in the write program. The write program doesn't seem to have a toggle or option to quit it after the first send so you will never be able to end this script without having to resort to interrupting it (Ctrl + z or d).

Error found. Was my bad, thanks Henrik!
