mpstat - which I think is part of package of utilities in Debian; maybe sysstat.

It's used for the default cpu_usage script for i3blocks:

use strict;
use warnings;
use utf8;
use Getopt::Long;

# default values
my $t_warn = 50;
my $t_crit = 80;
my $cpu_usage = -1;

sub help {
    print "Usage: cpu_usage [-w <warning>] [-c <critical>]\n";
    print "-w <percent>: warning threshold to become yellow\n";
    print "-c <percent>: critical threshold to become red\n";
    exit 0;
}

GetOptions("help|h" => \&help,
           "w=i"    => \$t_warn,
           "c=i"    => \$t_crit);

# Get CPU usage
$ENV{LC_ALL}="en_US"; # if mpstat is not run under en_US locale, things may break, so make sure it is
open (MPSTAT, 'mpstat 1 1 |') or die;
while (<MPSTAT>) {
    if (/^.*\s+(\d+\.\d+)\s+$/) {
        $cpu_usage = 100 - $1; # 100% - %idle
        last;
    }
}
close(MPSTAT);

$cpu_usage eq -1 and die 'Can\'t find CPU information';

# Print short_text, full_text
printf "%.2f%%\n", $cpu_usage;
printf "%.2f%%\n", $cpu_usage;

# Print color, if needed
if ($cpu_usage >= $t_crit) {
    print "#FF0000\n";
    exit 33;
} elsif ($cpu_usage >= $t_warn) {
    print "#FFFC00\n";
}

exit 0;

You can find some bash scripts using it if you check out the i3, dwm (tiling wm's in general) threads and see how their status bars are set up.

There is also the psutil suite if you want to go with python.

top -n1 | grep 'Cpu(s)'| awk '{print $2;}' | sed -e 's/id,//g'

that donne this

~/Bureau$ top -n1 | grep 'Cpu(s)'| awk '{print $2;}' | sed -e 's/id,//g'

how about this?

USER@HOST[~]$ top -n1 | grep 'Cpu(s)'| awk '{print $2;}' | cut -c1-1
5

i try the cut -c1-2 ( done 7, work great with number who begin with 10 ) & c1-3 (done 8,1 or 12,)

I have this

# cpu usage in percents 
tmp=$(ps -A -o pcpu | tail -n+2 | paste -sd+ | bc)
cpu=$(awk_round 0 "$tmp")
echo "$cpu% cpu used"
