Comment:
Herewith, a couple of observations:
- The write error is not from `stat`, `tr` or anything like that. It's the kernel rejecting the values you're trying to write to `/sys/power/resume`.
- The output of the `ls` scrape is *not* the same as that from `stat`. `ls` prints device types in decimal, but `stat` prints hex values:
```
% ls -lH /dev/watchdog
crw------- 1 root root 10, 130 Jan 25 23:43 /dev/watchdog

% stat /dev/watchdog -c '%t:%T'
a:82
```
- Sometimes these sysfs writes are finicky, and a terminating newline can cause a problem. In the original `ls` scrape, you can try `echo -n` to suppress the new line. In the `stat` version, you can use `tr -d '\n'`.
