I downloaded dex2jar and now trying to use it, but if I type \'sh d2j-dex2jar.sh\' it shows the following message.
d2j-dex2jar.sh: line 36: ./d2j_invoke.sh: Perm
Still If you find no luck use,
chmod a+x *.sh
You need to provide execute permissions to your sh script.
To do that : sudo chmod +x d2j_invoke.sh
sudo chmod +x d2j_invoke.sh
