6. Appendix: escapes for other terminal types
Many modern terminals are descended from xterm or rxvt
and support the escape sequences we have used so far. Some proprietary
terminals shipped with various flavours of unix use their own
escape sequences.
6.1 IBM aixterm
aixterm recognises the xterm escape sequences.
6.2 SGI wsh, xwsh and winterm
These terminals set $TERM=iris-ansi and use the following escapes:
ESCP1.ystringESC\ Set window title to stringESCP3.ystringESC\ Set icon title to string
xwsh escapes see the xwsh(1G) man page.
The Irix terminals also support the xterm escapes to individually
set window title and icon title, but not the escape to set both.
6.3 Sun cmdtool and shelltool
cmdtool and shelltool both set $TERM=sun-cmd
and use the following escapes:
ESC]lstringESC\ Set window title to stringESC]LstringESC\ Set icon title to string
6.4 CDE dtterm
dtterm sets $TERM=dtterm, and appears to recognise both the
standard xterm escape sequences and the Sun cmdtool
sequences (tested on Solaris 2.5.1, Digital Unix 4.0, HP-UX 10.20).
6.5 HPterm
hpterm sets $TERM=hpterm and uses the following escapes:
ESC&f0klengthDstring Set window title to string of length lengthESC&f-1klengthDstring Set icon title to string of length length
A basic C program to calculate the length and echo the string looks like this:
#include <string.h>
int main(int argc, char *argv[])
{
printf("\033&f0k%dD%s", strlen(argv[1]), argv[1]);
printf("\033&f-1k%dD%s", strlen(argv[1]), argv[1]);
return(0);
}
We may write a similar shell-script, using the ${#string}
(zsh, bash, ksh) or ${%string}
(tcsh) expansion to find the string length. The following
is for zsh:
case $TERM in
hpterm)
str="\e]0;%n@%m: %~\a"
precmd () {print -Pn "\e&f0k${#str}D${str}"}
precmd () {print -Pn "\e&f-1k${#str}D${str}"}
