popd || return

# cleanup
rm -rf /tmp/rocksdb-${ROCKSDB_VERSION} /tmp/v${ROCKSDB_VERSION}.tar.gz

echo "installation successful"

# To uninstall
#make uninstall INSTALL_PATH=/usr

Thanks for pointing that out. Let me update the script. 👍

Might need sudo to play with /usr/lib and /usr/include folders. So,
sudo make install-shared INSTALL_PATH=/usr

@roshsoftco Thanks for the feedback. I think it's not a good practice to use sudo in scripts. We can run the script with root privileges when we execute it.

sudo ./install.sh

I have updated the script. This can be executed as a script now.

Alternatively we can execute this in the following way

curl -s https://gist.githubusercontent.com/srimaln91/bea81d8c5ba36a64b0cd1b3b5324f687/raw/ba679250ebf3917203d61c60f01da5c01f441874/rocksdb-install.sh | sudo  bash
