## 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 string`
- `ESCP3.ystringESC\ Set icon title to string`

For the full list of `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 string`
- `ESC]LstringESC\ Set icon title to string`

These are truly awful programs: use something else.

## 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 length`
- `ESC&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}"}
>             ;;
>     esac

> `
