Re: Make screen title flash ...

[Malte Skoruppa]

Hi,

maybe you could do something with a little bash script?
Remember that you can change the screen title from within the console by echoing a special control sequence, e.g. echo -n -e "\033kmy screen title\033\\"

Let us assume you have the title you want to make blink in a variable $TITLE

Then how about this:

# first we need a function that generates an
# empty string of the same length as $TITLE
makeblanks() {
 len=${#TITLE}
 BLANKTITLE=''
 for i in `seq $len`; do
  BLANKTITLE+=' '
 done
}

# now we have the title in $TITLE and the
# "blank" title in $BLANKTITLE
# all we need to do is alternate them every
# second or so
blink() {
 makeblanks
 status=0
 while [ true ]; do
  sleep 1
  if [ $status -eq 0 ]; then
   echo -n -e "\033k$BLANKTITLE\033\\"
   status=1
  else
   echo -n -e "\033k$TITLE\033\\"
   status=0
  fi
 done
}


Now all you need to do when you want to make your screen title flash is call the function blink
This can certainly be improved; e.g. maybe you don't want to have an infinite loop there, or it will never stop blinking... but I just wanted to give the key idea. :-)

Cheers,

Malte
