Taking BusID output from lspci and storing in a variable

  • 772

I am trying to get the BusID's of each video card stored in a server and putting them in a variable each to be used for an input to a simple find and replace perl script. How would I go about getting the BusID's of each device listed when I run "lspci | grep VGA" for example.

Thanks

bash shell-scripting lspci

  1. You can use awk to delineate output by spaces. In the fragment below, (assuming a single line was returned by the lspci | grep VGA) the $1 refers to the first component up to a space. $2 would be VGA, $3 compatible, etc ... like this:

    00:0f.0 VGA compatible controller: VMware Inc Abstract SVGA II Adapter

    In Bash, you would extract the component via awk and assign it to $var, like so:

    var=$(lspci |grep VGA | awk '{ print $1 }')

    echo $var should return 00:0f.0
