jk_cp - a utility to copy files including permissions and libraries into a jail


jk_cp -j jail source

jk_cp -v -k -f -j jail source


jk_cp will copy any file into a jail on the identical location, with identical permissions and (if required) including any required libraries. It will remove any set user id (setuid) or set group id (setgid) permissions from all files and directories copied..


jk_cp -j /home/testchroot /usr/bin/cvs

will copy /usr/bin/cvs to /home/testchroot/usr/bin/cvs, and it will copy the libraries used by cvs also to the jail..

jk_cp -k -j /svr/testjail /usr/bin/firefox /usr/share/firefox

will hardlink /usr/bin/firefox and all files in /usr/share/firefox into jail /svr/testjail


-j --jail The destination jail. If no jail is specified, the first argument is used as jail for backwards compatibility

-f --force Force overwriting of existing files

-k --hardlink Try to create hardlinks instead of copying the files. If linking fails it falls back to copying..

-o --owner Retains the file ownership and group when copying files and directories..

-v --verbose Will give verbose output

-h --help The help screen
