Failed ~20 times for me. And the more, the more I run the test.
What is more curious, is if I modify your test to only print "1",
while true; do
echo > /dev/clipboard
for n in {1..10}; do echo $n; done > /dev/clipboard
grep -q 10 /dev/clipboard || grep 1 /dev/clipboard
done
it sporadically print 10 !
And my mail client actively flashing "paste" buttons, when the script is
working in background. May be that's it.
This is more visible:
$ while true; do { i=$(( $i+1 )); echo > /dev/clipboard; for n in {1..10}; do
echo $n; done > /dev/clipboard; grep -q 10 /dev/clipboard || { grep 10
/dev/clipboard && echo $i;};}; done;
