how to uninstall git in centos
If you were smart enough and used some non-standard prefix when configured Git so that it has been installed under a specific hierarchy, like under /opt/git, then just delete that hierarchy, recursively.
If not, then you could go like this:
1) Fetch the source tarball of exactly the version you built and installed, unpack.
2) Configure it exactly like you did with the original install with regard to installation locations (prefix, exec-prefix etc); supposedly you should just not override anything.
3) Create a temporary directory to perform installation, like this: $ mkdir /var/tmp/git
4) Install Git passing a proper DESTDIR variable to make: $ make DESTDIR=/var/tmp/git install The Git hierarchy will end up created under that temporary directory.
5) Use the created hierarchy to decide which files to delete under the real hierarchy (“/” itself).
The last step is where “the magic” happens so it bears more explanation. For instance, you could run
$ find /var/tmp/git -type f -printf '/%P\n' | xargs -n 10 rm -f
(as root) do delete the files installed by the first mis-installation into the root filesystem. The encantation above uses the /var/tmp/git hierarchy to print the list of files found, but it replaces the “/var/tmp/git” prefix in them with “/”, so that the “/var/tmp/git/usr/bin/git” in the output will end up listed as “/usr/bin/git”. This list is then piped to
xargs which runs
rm on the file names it reads in packs of ten (just to reduce the number of invocations of
rm by one order of magnitude).
After dealing with files, run
$ find /var/tmp/git -type d -printf '/%P\n'
to inspect the list of installed directories. These require manual approach so just look at the generated list and think which of them you could safely
rmdir from your system (these will be the directories like “/usr/libexec/git” or something like this; you wouldn’t probably want to delete “/usr/share/man/mann” or something even if it’s empty).
P.S. In the future never install anything into a system by running
make install! Most makefiles these days do not support “uninstall” target as they are used to either installing into a private scratch location for testing or to make a package (.rpm, .deb etc) and then the package manager takes care of cleaning up. If you need to install something, try to find an official package or try to backport another official package from a more recent version of your OS, if available. As the last resort, try using the
checkinstall tool which tries to create a binary package out of your
make install run. This sucks, but still better than bare
