I have HP 32-bit laptop with ubuntu 16.04 lts OS. I want to install a software which comes with .sh (e.g. abcd.sh). Now I download this file in Download folder, and from terminal I go to this folder first and ran:
$ cd Download
$ ./abcd.sh
bash: ./abcd.sh: Permission denied
Whats wrong with all those commands? How can I execute the file?
bash ./filename.sh
