SYNOPSIS

10       applydeltarpm [-v] [-p] [-r oldrpm] deltarpm newrpm
11       applydeltarpm -c|-C deltarpm
12       applydeltarpm [-c|-C] -s sequence
13       applydeltarpm -i deltarpm

DESCRIPTION

17       applydeltarpm applies a binary delta to either an old rpm or to on-disk
18       data to re-create a new rpm. The old rpm can be specified with  the  -r
19       option, if no rpm name is provided on-disk data is used. You can use -p
20       to make applydeltarpm print the percentage of completion, or -v to make
21       it more verbose about its operation.
22
23       The  second an third form can be used to check if the reconstruction is
24       possible. It may fail if the on-disk data got  changed  (deltarpms  are
25       created  in  a  way  that  config  file  changes  do not matter) or the
26       deltarpm does not match the rpm the delta was generated  with.  The  -c
27       option  selects  full  (i.e.  slow)  on-disk  checking, whereas -C only
28       checks if the filesizes have not changed.
29
30       Instead of a full deltarpm a sequence id  can  be  given  with  the  -s
31       sequence option. Such an id contains all the information that is needed
32       to do reconstruction checking.
33
34       Finally information about a deltarpm can be printed with the -i option.

EXIT STATUS

38       applydeltarpm returns 0 if the rpm could be recreated or  the  checking
39       succeeded,  it returns 1 and prints an error message to stderr if some‐
40       thing failed.
