For consistency, inline this sysfs also (thus ``/sys/bus/coresight/devices``. > +e.g. e.g.:: (make the shell snippet below code block) > +/sys/bus/coresight/devices # ls -l | grep dummy IMO I prefer `PS1=\$` (that is, omit the directory). Alternatively, you can write `ls -l /sys/bus/coresight/devices | grep dummy` (specify the directory to `ls`). Thanks. -- An old man doll... just what I always wanted! - Clara
