It is suggested that on Linux, GPU be found with the command lspci | grep VGA. It works fine on Ubuntu but when I try to use the same on CentOS, it says lspci command is not found. How can I check for the GPU card on CentOS. And note that I'm not the administrator of the machine and I only use it remotely from command line. I intend to use the GPU as a GPGPU on that machine, but first I need to check if it even has one.

This assumes you have proprietary drivers installed, but issue the following command...

nvidia-smi

The output should look similar to this:
