[tcprobe] summary for test.avi, (*) = not default, 0 = not detected
import frame size: -g 576x256 [720x576] (*)
frame rate: -f 25.007 [25.000] frc=0 (*)

You will need to use cut or awk:
tcprobe -i test.avi | grep length | cut -d" " -f2
tcprobe -i test.avi | grep length | awk {'print $2'}

THX for help solved the problem with following script:

------------------------------------------------------------------------------------
tcprobe -i "$*" > movieinfo.tmp

FRAMES=`grep '\[avilib\] V:' movieinfo.tmp | \
perl -e ' $line=<STDIN> ; $line =~ /frames=(\d+)/ ; print $1' `

MIN_TOTAL=`echo "scale=0 ; ($FRAMES / 1440)"| bc -l`

echo $MIN_TOTAL

rm movieinfo.tmp -f
-----------------------------------------------------------------------------------

script prints movielenght in min
