identify M.2 SSD from BASH Script

rated 0 times [ 2] [ 0] / answers: 1 / hits: 2629 / 2 Years ago, mon, august 22, 2022, 2:44:14

I am writing an installation automation BASH script. I'd like to install the nvme-cli package only if an NVMe SSD is actually present.
I couldn't find a simple way to query the hardware (say, using lshw) to get a kind-of-yes-or-no answer.
Any of you can give a way to extract the specific answer from within a BASH script?
I'd like to use the case conditioning to either install it or not.

In some cases, free space is an issue, besides, i am a firm believer in not installing redundant packaged as a rule, so, eventually I went with:

 NVMECOUNT=`lsblk | grep nvme | wc -l`

    if [ $NVMECOUNT -gt 1 ]

    then 

        apt -y install nvme-cli

    fi

Thanks!
