Hi Baskar,
you can try this
i=1
cd *test*
for name in `ls | sort`;
do
temp=`echo $name | cut -c 1-3`;
if [ $i -lt 10 ]
then
newname=$temp;
newname+="0$i.mp4";
echo $name renamed to $newname;
mv $name $newname
else
newname="$temp$i.mp4";
echo $name renamed to $newname;
mv $name $newname
fi
i=$((i+1));
done
cd ..
change it to directory you want.
I executed in bash and it worked i can see the new files like
M1L01.mp4
M1L02.mp4
M1L03.mp4
M1L04.mp4
M1L05.mp4
M1L06.mp4
M1L07.mp4
M1L08.mp4
M1L09.mp4
M1L10.mp4
M2L11.mp4
M2L12.mp4
M2L13.mp4
M2L14.mp4
M2L15.mp4
M2L16.mp4
M2L17.mp4
M2L18.mp4
M2L19.mp4
M2L20.mp4
M3L21.mp4
M3L22.mp4
M3L23.mp4
M3L24.mp4
M3L25.mp4
M3L26.mp4
M3L27.mp4
M3L28.mp4
M3L29.mp4
M3L30.mp4
I kept the first 3 letter as it is if you want you can remove them in the
newname calculation

That is the question I had asked in my previous reply. What should be
the expected behavior in such a case?
There could be 'n' number of modules (referred as M) and those modules may
have 'n' no.of number of lectures (referred as L).
Now the requirement is to remove the modules from the filenames and have
only lectures in consecutive numerical order
If the directory has files names like this,
M1L1.mp4
M1L2.mp4
M1L3.mp4
M2L1.mp4
M2L2.mp4
M2L3.mp4
M2L4.mp4
M3L1.mp4
M3L2.mp4
Then, the resulting file list should be as below (were M followed by 'n'
value can be removed)
L1.mp4
L2.mp4
L3.mp4
L4.mp4 (here M2L1 should automatically get renamed to L4)
L5.mp4
L6.mp4
L7.mp4
L8.mp4 (here M3L1 again should automatically get renamed to L8)
L9.mp4
