> Hello. As mentioned before, I have a problem with: > bzcat ../loop-AES-v3.2e-20090112.diff.bz2 | patch -p1 && > > The && is useless because of the |. I think the && is using the return value > from bzcat, and not from patch. Redirection would work, except that the patch > is bzip2 compressed. For example: > patch -p1 < ../loop-AES-v3.2e-20090112.diff > works, but > patch -p1 < $(bzcat ../loop-AES-v3.2e-20090112.diff.bz2) > does not (ambiguous redirect). > > Is there another way, aside from decompressing the patch in the sources > directory? that work bzcat ../loop-AES-v3.2e-20090112.diff.bz2 | (patch -p1 && echo ok) echo ok is just there as a visual check to verify && work as intended. openswan was using a similar construction to patch the kernel on previous releases. that was more like | (cd $(DIR_APP) && patch -p1) and when I forgot the (), nothing was done.
