According to http://www.in-ulm.de/~mascheck/various/echo/ SunOS 4 does not have printf, but most others do. There are several other ways to set the title. Replace the hostname|sed;echo with hostname | awk -F. '{printf("\033]2;%s\007\033]1;%s\007", $1, $1)}' the -F. splits the input on periods, and the printf does the work of echo. In case some old version of awk does not support the \nnn format, you can use hostname | awk -F. '{printf("%c]2;%s%c%c]1;%s%c", 27, $1, 7, 27, $1, 7)}' Another is to embed the control characters directly into the string #!/bin/sh echo "^[]2;$*^G^[]1;$*^G\c" You can type the control characters in vi with Control-V Escape, and Control-V Control-G, or emacs with Control-Q... I do it this way (I don't remember which system forced me this way, HPUX or Irix most likely). I put these into a separate script because the simple act of viewing the file (more, less, cat) will change the title and icon. Of course, this takes you directly into the differences in ways that echo suppresses newlines - or not in the case of posix.2.
