rpmscomp - compare RPMs installed on multiple systems, or compare versus previously recorded list of installed packages
rpmscomp [OPTION]... [[USER]@HOST]... [FILE]...
rpmscomp --record [OPTION]... [[USER]@HOST]...
Compare the RPMs installed on the specified systems and/or recorded within the specified files.
| -d, --diffonly | Only list differences |
| -h, --help | Print a help message and exit |
| -r, --record | Record mode (record installed RPMs for later) |
| -v, --verbose | Verbose mode |
| -f, --force | Force overwrite of output files |
| -o, --output | Write a list of installed RPMs to this file name. If multiple HOSTs are specified, this specifies a prefix, and the host name will be appended. |
If you specify a host as @HOST, rpmscomp will ssh to HOST in order to determine what RPMs are installed on that host.
If you specify a host as USER@HOST, rpmscomp will ssh to HOST as USER in order to determine what RPMs are installed on that host.
If you provide an argument that doesn't begin with @, rpmscomp will assume this is a file name containing a previously recorded list of RPMs installed on some host.
If you specify no hosts in --record mode, rpmscomp will assume you want to record the RPMs installed on @localhost.
if you specify only a single host in normal (compare) mode, rpmscomp will assume you want to compare versus @localhost.
You can specify as many hosts and/or files as you want to compare (there is no hard limit other than what may be imposed by the amount of memory in your systems).
rpmscomp @server1
This will ssh to server1, retrieve a list of all the RPMs installed on that host, then print out a comparison of the RPMs installed on server1 versus the local host.
rpmscomp @server1 @server2
This will ssh to server1 and server2, retrieve a list of all the RPMs installed on each host, then print out a comparison of the RPMs installed on both hosts.
rpmscomp --diffonly @server1 @server2
This will ssh to server1 and server2, retrieve a list of all the RPMs installed on each host, then print out a comparison of the RPMs installed on both hosts, but only showing RPMs where the installed version, release, or architecture(s) differ between the hosts.
rpmscomp user1@server1 user2@server2
This will ssh to server1 as user1, ssh to server2 as user2, retrieve a list of all the RPMs installed on each host, then print out a comparison of the RPMs installed on both hosts.
rpmscomp @server1 @server2 @server3 @server4 @server5 @server6
This will ssh to server1 through server6, retrieve a list of all the RPMs installed on each host, then print out a comparison of the RPMs installed on both hosts.
rpmscomp --record @server1 @server2
This will ssh to server1 and server2, retrieve a list of all the RPMs installed on each host, and record that information in files (server1 for the server1 list and server2 for the server2 list). If a file that would be written to already exists, it will not be overwritten.
rpmscomp --record --force @server1 @server2
This will ssh to server1 and server2, retrieve a list of all the RPMs installed on each host, and record that information in files (server1 for the server1 list and
server2 for the server2 list). If a file that would be written to already exists, it will be overwritten.
rpmscomp --record --output server1.2013-01-01 @server1
This will ssh to server1, retrieve a list of all the RPMs installed on that host, and record that information in the file server1.2013-01-01. If the file that would be
written to already exists, it will not be overwritten.
rpmscomp --record --output myprefix @server1 @server2
This will ssh to server1 and server2, retrieve a list of all the RPMs installed on each host, and record that information in files (myprefix.server1 for the server1
list and myprefix.server2 for the server2 list). If a file that would be written to already exists, it will not be overwritten.
rpmscomp myprefix.server2 @server2
This will retrieve a previously stored list of RPMs installed from the file myprefix.server2, then ssh to server2, retrieve a list of all the RPMs installed on that host, then
print out a comparison of the RPMs lisetd in myprefix.server2 versus those currently installed on server2.
