Instead, it will highlight the. Ive found useful in the real world. For simplicity, I will assume all software on your system has. Querying Your System. The first thing you should do is look and see what software. Here is the command to use. In case you are unfamiliar with the command line, let me break. It tells. the computer you want to run the rpm program. In unix, the set. The q tells rpm you want the query operation. The following. a in the qa is a modifier for the query option. The more. part of the above command is not a feature of rpm at all. It. is a standard unix way to show output one page at a time. If this. seems confusing, dont worry about it. Itll become second. The package info is split into three pieces. The first piece is the package. The second is the software version number. And, the third is. All three are seperated by dashes. The. package build number is important incase if there is a more recent. This happens a lot with the. If you see a package with more than two dashes, like. Ive found it is easiest to start on the right. The package name in this case is glibc devel. Lets work with an example. Suppose you query all the packages in your. What is it and how can you find. We can query individual packages like this. The i query option requires a package name. Notice that I used. Rpm is smart enough to use the. Supplying the version info. Now that you know what the faq package is, can you see which. Absolutely This command should look similar to the previous one. All we did was. replace the i with an l to get a listing of files installed. Installing New Software. Lets look at the command to add new software. The i is the install switch. At Least One Service Or Driver Failed During Startup Server 2003 more. I like to use the v for. The h. option shows our progress with hash marks. If nothing else, it entertains. A variation on an install is an upgrade. An upgrade is. used when you want to put a more recent package in place of something. The upgrade syntax. U. Notice it is a capital U If a new. Uvh xsnow 2. 0 1. One last thing that I should mention is that we are installing binary. My Intel chip is not binary compatible with an Alpha and so on. The convention for rpm files is to have the architecture preceding the. Some packages, like man pages, will have noarch. It means that the package is not dependant on the. CPU you have. Removing Unwanted Software. A major advantage to a packaging system like rpm is its ease to. Here is how you do it. There isnt much more to it. Occationally there may be an error that. We can avoid the dependency check with the nodeps option. I should warn you to think before you do this. Rpm has been smarter. If you break something, all I can say is. Verifying Installed Packages. Package verification is something that I dont use a lot, but its good. Verifying a package compares information about. Among other. things, verifying compares the size, MD5 sum, permissions, type, owner. Only the discrepencies are displayed. See. the man page for more information Thats where I pulled most of this info. Why verify at allIf youre up too late and go on a random file. Another. more serious use is if youre system has been hacked into. Rpm can. verify all of your files to see if you were left backdoors or. Here is how. This command will verify all of the files on your system. The syntax. should remind you of how you queried your software. Some of the. files it reports will be normal. For example, almost everyone will. The file has changed since. Disclaimer If your system security has been compromised, rpm. It is not sufficient to only. Advanced Queries. What if you find a file and have no idea what it is or where it came. Rpm can query that file and show you the package it originated from. This command is a little different because it requires the full. Rpm cannot follow symbolic links to a file. You have looked at files that are already installed, but can you. Yes, query with the p option. Notice the ql is the same as the first section. The third. arguement to the command is a little different than before. We. used the filename instead of the shorter package name. That is. because we are looking into a file, not something that has already. Sometimes a package is not removed cleanly. Here is the situation. You. then try to remove it, and rpm says that is not installed. What can you do rpm ivh force package 1. The force option is your solution. Dependencies are generally regarded as a good thing. Rpm has. the capability to know if software has such prerequisites. In. the real world, not everything on your system can always be from. If I install the new libxxx without rpm, then I install. I can use the nodeps to tell rpm that I dont need it. Now you may be thinking that it sucks that not all software. The good news is that you can build your. The bad new is it is beyond the scope of this document. You can find that info in the official. Additional Resources. Written by Brian Murphy.
