Description Niels Laukens 2006-12-04 10:25:20 UTC

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'`
