Cat

cat/<path to filename> - to display the content of a file

  e.g. cat//config/device.cert.pem -- display the /config/device.cert.pem file content

       cat/<path> -line <num> -- display only <num> of lines, like 'head' if <num> is positive, like 'tail' if the <num> is negative

This is simply the Linux 'cat' utility to display a file's content. the file starts from the full path from the EVE Linux root directory.

The option can take a '-line <num>', and this is similar to Linux 'head' and 'tail' utility to only display the number of lines from the file depends on the <num> is a positive or negative value. For example to tail the last 5 lines of the current device log:

eddgeview.sh cat//persist/newlog/collect/current.device.log -line -5

content type: text/plain; charset=utf-8
