PROGRESS STATUS IN XTERM TITLEBAR

Sometimes it is handy to be able 
to show some information in the 
xterms title bar, for example
if you download a set of large 
files (thereby producing lots 
of meaningless information on 
the terminal) and you want to 
know which file is actually 
beeing downloaded.

For this purpose, I hacked a few 
lines of shell code that would 
put any information into the 
xterms title bar. I called the 
script ttshow.

#!/bin/sh
if [ -z $DISPLAY ]; then
        echo "ESC]0; $* ^G"
fi

In this little script, the 
string ESC has to be replaced 
by one real escape character 
(ascii 0x1b), the string "^G" 
has to be replaced by a bel 
character (ascii 0x07).

Now I can make my scripts like 
this:

for file in in `cat filenames`; do
        ttshow "downloading $file"
        wget $file
done

..and it will tell me on the 
first glance what it's doing.

For more information about 
this, unpack the X distribution 
and search for the file 
ctlseqs.ms - this file belongs 
to the xterm distribution and 
contains all the escape 
sequences xterm knows about.
