>Description:
This cmd works fine on Solaris, Linux, etc.:
echo "dhopper.dummynet.:0 MIT-MAGIC-COOKIE-1 00000000000000000000000000000\
000" | xargs xauth add
but it bombs on FreeBSD (3.0R) with:
xauth: (argv):1: bad "add" command line
Take the pairs of spaces and replace them with one space:
echo "dhopper.dummynet.:0 MIT-MAGIC-COOKIE-1 0000000000000000000000000000000\
0" | xargs xauth add
and it works fine.
Seems like a bug in xargs processing. This clearly shows the problem:
echo "dhopper.dummynet.:0 MIT-MAGIC-COOKIE-1 000000000000000000000000000000000" | xargs -n 1 echo "ARG: "
ARG: dhopper.dummynet.:0
ARG:
ARG: MIT-MAGIC-COOKIE-1
ARG:
ARG: 00000000000000000000000000000000
>How-To-Repeat:
Run the last command above and observe that 5 args are passed to echo
instead of 3.
>Fix:
Thanks.
