how to uninstall software on Linux


Sorry , this is a easy question but I am new

I install backup agent client on the linux server 2.1. During the installation, there is a default to /opt and I click yes and I guess the software was installed in the folder. After playing with it , I delete the backup agent folder under /opt and when I tried to install the software again, it said the software already installed.

the question is how can uninstall the software so I can reinstall it again.

thank

How did you install the software? If you used a script, there is frequently an option to clean past installations. If you used rpm, try rpm -U.

actually the -U flag for rpm is to upgrade a package to remove a package the flag is rpm -ev <packagename> the v giving u verbose output of what is actually being uninstalled and if by uninstalling that package the v helps you to determine if your going to break dependencies.

what they mean by rpm -ev (and not U) is the following:
rpm -ev packagename
of course if you simply right rpm -ev, rpm cannot know what file to remove. You need the package name, which you use when you install. To find it you can try:
rpm -qa|grep name
where name is the name of the package.
this should print the a longer package name which typically goes:
package-name-rh9-i386.rpm

(These are really basic informations that has been repeated numerous times on this group. You have to read about these on documentation pages!)

But if you ran a script then the answer is not rpm. You should read the INSTALL file, perhaps they explain how to remove this software there.

Yes, you need to type the package name. (You will frequently see Unix commands given with a particular flag, but without specifying that you have to type the file name or input file and output file. I suppose I shouldn't follow that habit here.)

But if you ran ./install (without reading the script), rpm will not help you.

Yes, gbell, -U does upgrade, rather than remove. Since the original poster said they wanted to reinstall, it seemed like an easier move.

My apologies for skipping steps.
