Figure 1: The ic.txt map fields

field 1: cd to this place first
field 2: directory or source link
field 3: destination link
field 4: platform: all,sun,hp,sgi,sol
field 5: initially, this may be a type d=directory f=file or l=link
field 6: type, d=directory f=file or l=link
field 7: protection if file or directory
field 8: uid if file or directory
field 9: gid if file or directory

Example 1:

/usr/lib:sendmail::all:f:f:4755:root:staff

cd to /usr/lib
since field 5 is f, /usr/lib/sendmail, a file may exist, save a timestamped copy
since field 6 is f, this indicates that a file needs to be copied in place

ic action: cd /usr/lib
ic action: mv sendmail sendmail.$uniqid
ic action: cp $tdir/sendmail /usr/lib/sendmail

since field 7,8, and 9 are set, this indcates that chown and chmod must be run

ic action: chown sendmail root.staff
ic action: chmod sendmail 4755

Example 2:

/etc:motd:/usr/local/adm/motd:all:f:l:::

cd to /etc
since field 5 is f, /etc/motd, a file may exist, save a timestamped copy
since field 6 is l, this indicates that a link needs to be made

ic action: cd /etc
ic action: mv motd motd.$uniqid
ic action: ln -s /usr/local/adm/motd motd
