I started a new build of current dev LFS, and noticed some strange behavior from tar once inside chroot. Using tar 1.23, attempting to pipe its "tf" output through "head" results in a "tar: write error". In other words...
tar -tjf /home/sources/glibc-2.11.1.tar.bz2 | head -n1 glibc-2.11.1/ ./tar-1.23/src/tar: write error I do not get any kind of error message when just using "tar -tf" by itself, only when piping through "head". Also, I tried piping through various other programs (grep, sed...) and got nothing. Initially I thought there was some problem with filesystems mounted or something like that in the chroot, but I get exactly the same result on my host system. In fact, if I unpack tar 1.22 and do "./configure && make", then do the same with tar 1.23, and try using the "tf" option with both versions of tar (this is on my host system)... ch...@chris_laptop:~$ ./tar-1.22/src/tar -tjf /home/sources/glibc-2.11.1.tar.bz2 | head -n1 ./tar-1.22/src/tar: Record size = 8 blocks glibc-2.11.1/ ch...@chris_laptop:~$ ./tar-1.23/src/tar -tjf /home/sources/glibc-2.11.1.tar.bz2 | head -n1 glibc-2.11.1/ ./tar-1.23/src/tar: write error ch...@chris_laptop:~$ I also get the same result inside chroot. My host system is a few-months-old CLFS build with EGLIBC, and the chroot environment is a current LFS dev build, so there are different versions of both libc and Coreutils, but I get the same results. I don't know why it seems to come up only when piping through head, and it doesn't really seem to affect anything - my scripts (which use tar tf | head and are the reason I noticed this in the first place) still seem to work fine. I just want to verify if anyone else gets the same result - basically take Tar 1.23, do "tar tf [filename] | head" and see what happens. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
