For example ...
There are a lot of ways, for example you can try with:
cd /<your_directory>
for myfile in *.xyz
do
file_name=`echo $myfile |awk '{print substr($1,1,length($1)-4)}'`
echo "mv $file_name.xyz $file_name.abc"
done
Note: when you are sure remove the echo and the quotes.
from: echo "mv $file_name.xyz $file_name.abc"
to: mv $file_name.xyz $file_name.abc
