or better only the index 3. But the call have to be robust that I never would get Choice 13 with 2000.
I gave you a solution to this.
Even for just the value, show some adaption effort.
Or describe what you really want and share what you've done.

Thank you.

If I understand what you're trying to do, this seems to work:
Code:
gphoto2 --get-config /main/imgsettings/iso | awk ' 
/^Current/ { speed = $2; next }
speed && $3 == speed { print $2; exit }'

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk.

Super-safe (speed=0, leading space, ...)
Code:
gphoto2 --get-config /main/imgsettings/iso | awk '
$1=="Current:" { speed=$2; f=1 }
f==1 && $1=="Choice:" && $3==speed { print $2; exit }'

Thank y all for y support.
There is another solution but only with sed:
Code:
ghoto2 --get-config /main/imgsettings/iso | sed -n "/Current: /h;G;s/Choice: \([0-9]\+\) \(.*\)\nCurrent: \2/\1/p"

I think that a 200 would match a 2000. An attempt to make it more robust:
Code:

ghoto2 --get-config /main/imgsettings/iso |
sed -n '
/^ *Current:/{
s/.*: *//
h
}
G
s/^ *Choice: *\([^ ]*\)  *\([^ ]*\) *\n\2 *$/\1/p'

But awk is a better choice here because of its splitting on white-space.
