This bug should probably go directly to the BusyBox bug-tracker; but I wanted to verify that I'm not alone on this. Probably the busybox-dev's will start asking difficult questions for things like libraries and link-options; and I'd like to have same support then. busybox sh TEST="`echo abc | sed -n '/abc/p'`"; echo $TEST # gives abc, as expected busybox.static sh TEST="`echo abc | sed -n '/abc/p'`"; echo $TEST # gives empty line!!!!!!! This bug hit me when trying to make an initramfs (hence the need for the static binary); it took me 3 hours to pin it down to the usage of sed INSIDE backticks (or the $() construct). Can anyone confirm this bug?
I tried this bug myself on different machines: all dynamicaly linked versions work perfectly, for the static-versien: * 1.1.0 works * 1.2.1 works * 1.2.2.1 FAILS (on 3 different machines) Also, it seems to be more general than only sed. These also fail (but DO work OUTSIDE backticks): * echo `echo abc | grep abc` but these work: * echo `echo abc | awk '/abc/p'`
