Named pipe with shell command date

  • 772

I want to let a standard user change the system date.

So I created a named pipe. The standard user write a date to the named pipe and a root process listens to it and sets the date accordingly:

(user)

echo 122515502010 > /tmp/mypipe

(root)

date -s < /tmp/mypipe

Unfortunately this doesn't work. Where am I wrong?

I'm doing this from an embedded Linux (busybox) with bash.

linux bash busybox date named-pipes

  2. Why not give the user access to date via sudo ?
