These files will then be compared 111against the currently installed files in the 112.Pa /etc 113directory. By default this is 114.Pa /tmp/temproot 115but it can be changed either with the 116.Fl t Ar temproot 117argument or by defining the 118.Ev TEMPROOT 119variable. 120.It Ev SRCDIR 121The location of the 122.Nx 123sources files. By default this is 124.Pa /usr/src/etc 125but it can be changed either with the 126.Fl s Ar srcdir 127argument or by defining the 128.Ev SRCDIR 129variable. 130.It Ev PAGER 131The pager to use when displaying files. By default this is 132.Xr more 1 133but it can be changed either with the 134.Fl p Ar pager 135argument or by defining the 136.Ev PAGER 137variable. 138.It Ev WIDTH 139The screen width used during interactive merge. By default this is 14080 but it can be changed either with the 141.Fl w Ar width 142argument or by defining the 143.Ev WIDTH 144variable. 145This is useful for 146.Xr xterm 1 147users with wider shell windows. 148.El 149.Sh FILES 150The environment variables can also be defined in the following configuration 151files. The user's personal configuration file settings override the global 152settings. 153.Pp 154/etc/etcupdate.conf 155.Pp 156~/.etcupdaterc 157.Sh EXAMPLES 158You have just upgraded your 159.Nx 160host from 1.6 to 1.6.1 and now it's time 161to update the configuration files as well. 162To update the configuration files from the sources (if you have the 163.Pa /usr/src/etc 164directory): 165.Pp 166.Dl etcupdate 167.Pp 168The default location of the source files is 169.Pa /usr/src/etc 170but this may be overridden with the 171.Fl s Ar srcdir 172command line argument: 173.Pp 174.Dl etcupdate -s /some/where/src/etc 175.Pp 176To update the configuration files from binary distribution sets 177do something like this: 178.Pp 179.Dl mkdir /tmp/temproot 180.Dl cd /tmp/temproot 181.Dl tar xpzf /some/where/etc.tgz 182.Dl etcupdate -b /tmp/temproot 183.Pp 184To get a better idea what's going on, use the 185.Fl v 186flag: 187.Pp 188.Dl etcupdate -v 189.Sh HISTORY 190The 191.Nm 192command appeared in 193.Nx 1.6 . 194.Sh AUTHORS 195The 196script was written by Martti Kuparinen <martti@netbsd.org> and 197improved by several other 198.Nx 199users. 200.Pp 201The idea for this script (including code fragments, variable names etc.) 202came from the 203.Fx 204mergemaster (by Douglas Barton). Unlike the 205.Fx 206mergemaster, this does not use CVS version tags to compare if 207the files need to be updated. Files are compared with 208.Xr cmp 1 209as this is more reliable and the only way if the version numbers are the 210same even though the files are different. 211
