Summary: sed with in-place operation (-i switch) truncates file to zero (i.e. file is lost)

Description ecaddict 2011-08-16 08:24:24 UTC 
Correct behavior:
echo -e "ln1\nln2\nln3\nln4" > /tmp/sedtest && /bin/sed '1,2d' /tmp/sedtest
produces (as expected)
ln3
ln4


Error:
echo -e "ln1\nln2\nln3\nln4" > /tmp/sedtest && /bin/sed -i '1,2d' /tmp/sedtest && cat /tmp/sedtest
truncates the file (makes it empty, so cat does not show any content)
