It is .Sy HIGHLY recommended that you back up your .Pa /etc directory before beginning this process. .Pp The script uses .Pa /usr/src/etc/Makefile to build a temporary root environment from .Pa / down, populating that environment with the various files. You can specify a different source directory with the .Op Fl m command line option, or specify the destination directory with the .Op Fl D option. It then compares each file in that environment to its installed counterpart. When the script finds a change in the new file, or there is no installed version of the new file it gives you four options to deal with it. You can install the new file as is, delete the new file, merge the old and new files (as appropriate) using .Xr sdiff 1 or leave the file in the temporary root environment to merge by hand later. .Pp By default it creates the temporary root in .Pa /var/tmp/temproot and compares the .Xr cvs 1 version $Id/$FreeBSD strings for files that have them, deleting the temporary file if the strings match. If there is no $Id string, or if the strings are different it compares the files themselves. You can also specify that the script ignore the $Id strings and compare every file. .Pp .Nm checks your umask and issues a warning for anything other than 022. While it is not mandatory to grant world read permissions for most configuration files, you may run into problems without them. If you choose a umask other than 022 and experience trouble later this could be the cause. .Pa /etc/master.passwd is treated as a special case. If you choose to install this file or a merged version of it the file permissions are always 600 (rw-------) for security reasons. After installing an updated version of this file you should probably run .Xr pwd_mkdb 8 with the -p option to rebuild your password databases and recreate .Pa /etc/passwd . .Pp The script uses the owner and group id's that the files are created with by .Pa /usr/src/etc/Makefile , and file permissions as specified by the umask. Unified diffs are used by default to display any differences unless you choose context diffs. .Pp .Nm will source scripts that you specify right before it starts the comparison, and after it's done running. The easiest way to handle this is to place the path to the script(s) in the appropriate variables in your .Pa .mergemasterrc file. The script sourced before comparison is named in .Ev MM_PRE_COMPARE_SCRIPT , and the one sourced after the script is done is .Ev MM_EXIT_SCRIPT . This is the recommended way to specify local modifications, or files that you want to give special handling to. This includes files that you want to be deleted without being compared. Because the named scripts are sourced from within .Nm , all of the script's variables are available for use in your custom script. .Pp The options are as follows: .Bl -tag -width Fl .It Fl s Perform a strict comparison, diff'ing every pair of files. .It Fl c Use context diffs instead of unified diffs. .It Fl r Re-run .Nm on a previously cleaned directory, skipping the creation of the temporary root environment. This option is compatible with all other options. .It Fl v Be more verbose about the process. You should probably use this option the first time you run .Nm mergemaster . This option also gives you a list of files that exist only in the installed version of .Pa /etc . .It Fl a Run automatically. This option will leave all the files that differ from the installed versions in the temporary directory to be dealt with by hand. If the .Pa temproot directory exists, it creates a new one in a previously non-existent directory. This option unsets the verbose flag, but is compatible with all other options. Setting -a makes -w superfluous. .It Fl h Display usage and help information. .It Fl i Automatically install any files that do not exist in the destination directory. .It Fl m Ar /path/to/sources Specify the path to the directory where you want to do the .Xr make 1 . (In other words, where your sources are, but -s was already taken.) .It Fl t Ar /path/to/temp/root Create the temporary root environment in .Pa /path/to/temp/root instead of the default .Pa /var/tmp/temproot . .It Fl d Add the date and time to the name of the temporary root directory. If -t is specified, this option must follow it if you want the date added too. .It Fl u Ar N Specify a numeric umask. The default is 022. .It Fl w Ar N Supply an alternate screen width to the .Xr sdiff 1 command in numbers of columns. The default is 80. .It Fl D Ar /path Specify the destination directory for the installed files. .El .Sh ENVIRONMENT The .Nm script uses the .Ev PAGER environment variable if set. Otherwise it uses .Xr more 1 . If .Ev PAGER specifies a program outside its limited .Ev PATH without specifying the full path, .Nm prompts you with options on how to proceed. The .Ev MM_PRE_COMPARE_SCRIPT and .Ev MM_EXIT_SCRIPT variables are used as described above. Other variables that are used by the script internally can be specified in .Pa .mergemasterrc as described in more detail below. .Sh EXAMPLES Typically all you will need to do is type .Nm at the prompt and the script will do all the work for you. .Pp To use context diff's and have .Nm explain more things as it goes along, use: .Pp .Dl # mergemaster -cv .Pp To specify that .Nm put the temporary root environment in .Pa /usr/tmp/root , use: .Pp .Dl # mergemaster -t /usr/tmp/root .Pp To specify a 110 column screen with a strict comparison, use: .Pp .Dl # mergemaster -sw 110 .Sh FILES .Bl -tag -width $HOME/.mergemasterrc -compact .Pa $HOME/.mergemasterrc .Pp .Nm will . (source) this file if it exists. Command line options will override rc file options. Here is an example with all values commented out: .Pp .Bd -literal # These are options for mergemaster, with their default values listed # The following options have command line overrides # # Directory to install the temporary root environment into #TEMPROOT='/var/tmp/temproot' # # Strict comparison bypasses the CVS $Id tests and compares every file #STRICT=no # # Flag(s) to use for diff displayed when files differ #DIFF_FLAG='-u' # # Verbose mode includes more details and additional checks #VERBOSE= # # Automatically install files that do not exist on the system already #AUTO_INSTALL= # # Sourcedir is the directory to do the 'make' in (where the new files are) #SOURCEDIR='/usr/src/etc' # # The umask for mergemaster to compare the default file's modes to #NEW_UMASK=022 # # Specify the destination directory for the installed files #DESTDIR= # # The following options have no command line overrides # For those who just cannot stand including the full path to PAGER #DONT_CHECK_PAGER= # # If you set 'yes' above, make sure to include the PATH to your pager -#PATH=/bin:/usr/bin:/usr/sbin:/sbin +#PATH=/bin:/usr/bin:/usr/sbin # # Don't compare the old and new motd files #IGNORE_MOTD=yes # # Specify the path to scripts to run before the comparison starts, # and/or after the script has finished its work #MM_PRE_COMPARE_SCRIPT= #MM_EXIT_SCRIPT= .Ed .Sh SEE ALSO .Xr cvs 1 , .Xr diff 1 , .Xr make 1 , .Xr more 1 , .Xr sdiff 1 , .Xr pwd_mkdb 8 .Pp .Pa /usr/src/etc/Makefile .Pp http://www.FreeBSD.org/handbook/makeworld.html , .Pa The Cutting Edge (using make world) , by Nik Clayton .Sh DIAGNOSTICS Exit status is 0 on successful completion, or if the user bails out manually at some point during execution. .Pp Exit status is 1 if it fails for one of the following reasons: .Pp Invalid command line option .Pp Failure to create the temporary root environment .Pp Failure to populate the temporary root .Pp .Sh HISTORY The .Nm script was first publicly available on one of my web pages in a much simpler form under the name .Pa comproot on 13 March 1998. The idea for creating the temporary root environment comes from Nik Clayton's make world tutorial which is referenced above. .Pp .Sh AUTHOR This manual page and the script itself were written by .An Douglas Barton Aq DougB@FreeBSD.org . .Sh BUGS There are no known bugs. Please report any problems, comments or suggestions to the author. Several of the improvements to this program have come from user suggestions. Thank you.
