If all you want to do is discover the current u.* device number that has been assigned to a particular textual device ID, and you're happy with parsing dmesg to do that, a starting point using sed would be: dmesg | sed -n -E 's/^u[a-z]*(.) .*ID_STRING.*/\1/p' | tail -1 Obviously refine as required for your particular use-case, but in principle it can be done fairly easily from the shell.
