This was from here.
Extract the patch
tar -xvzf /usr/src/web100-2.5.22-200810130047.tar.gz
bzip2 web100/ web100-2.6.27-2.5.22-200810130047.patch
Test the patch
bzip2 -dc /usr/src/linux/web100/ web100-2.6.27-2.5.22-200810130047.patch.bz2 | patch -p1 --dry-run
I looked at the .patch
, the diff output of many files and the file .patch.bz2
after the bzip2
command which is too also the diff output of many files, they seem to be the same. My question is why is bzip2 even needed to turn the .patch
into a .patch.bz2
? Is it for the redirection to std output from the -dc
option for the patch command? Even if it is, why not just not just use the patch command in the form something like this:patch -p1 < patchfile
? I don't see why the bzip2 is done here.
Also, I think the bzip2 might have an extra space in the command after web100/
, right?
