Fake Progress Bar in shell
Just to illustrate the use of "until" loop in BASH, here is a small script to generate a fake progress bar.
#!/bin/sh
clear
echo "Installation in Progress" [`basename $0`]
count=0
until [ $count -eq 10 ]
do
echo -n "###"
sleep 1
count=`expr $count + 1`
done
echo -n "[100%]"
echo
$ ./fakeprogress.sh
Installation in Progress [fakeprogress.sh]

Fake, but effective!
Thanks
Unfortunately I'm not as good as you, and I am beginner in the art of shell script, that would help me on a question: would implement a bar processro a command like?
pg_dump-h localhost postgres | bzip2-c / backup/backup_database.sql.bz2
Thank you for your patience and comprehension.
