Hi all

I am a civil engineering student using centOS on my desktop.

I feel really a bit silly asking this but I can't seem to figure this out. Recently I installed ENVI which is an image analysis software I am using for a class. Now I am done using it and I want to uninstall it. But I am not sure how.

I installed it using instructions from my university. I had a tar.gz file that I extracted and then installed using ./install.sh.

I just want to make sure I am uninstalling it cleanly without affecting anything else on the machine. I googled it and there are installation instructions for the software, but no uninstall instructions. Would I uninstall it using the RPM commands or something else? This I don't understand because I didn't install it via RPM. Any help is appreciated.

Unless you've also got a file called uninstall.sh in your home directory, it's probably time to examine the code for install.sh to see either (a) if it offers an uninstall option or (b) where it installed ENVI so you can uninstall it manually.

Are you able to paste those installation instructions here?

thank you both, here were the instructions for installing the software.

1. Unpack and uncompress the files:

Web download: Uncompress the filename.tar.gz archive file that was downloaded to your computer, then unpack the file:

gunzip filename.tar.gz
tar -xf filename.tar

2. Start the installer with one of these commands:

Web download: ./install.sh

3. Follow the prompts to install the software.

I got the installer from my university.

I do not see an uninstall.sh. It looks like it put the installation in /home and I see the directory for the software. Is there anything wrong with just going 'rmdir' on the directory if there is not an uninstall script, or is there a cleaner way to do this, in general, when there is not an uninstall option for software?

If the install script ONLY put files in directory under your /home and did not change any other external configuration files, it should be safe to delete the directory. Best to read through the install script first to see what it actually did.

I am reading through the install script and this is what it says. I remember when I ran the installer I specified that I wanted it in my /home directory. Reading through this text, I think I can confirm that /home was the only space where something was installed, could someone take a look at this for a sanity check? The only thing I don't understand is where it says INSTALL_DIR then points to /usr/local, but I just went there to check and there is no folder. Maybe that is where it installs the software if you do not specify another location.

Thanks a lot for the pointers. I am new to Linux and I don't know if I'll use it much in my career, in most of my core classes so far we are using Autocad, but it's always good to learn something new in case I run across this sometime

According to the installer, it appears to have asked you where you wanted to install the application during the install process. You should just delete that directory. There *may* be a few remnants around the place but they probably won't do any harm and your best bet would be to work through the script to find out where they are, search your filesystem for "envi" or equivalent, or ask your university how you install it.

OP - try to use code tags in your post next time if including code because it makes it easier to read. Thanks.

Just wanted to stop in and say thanks, I got it uninstalled on Wednesday and did not break anything Learned a lot browsing these forums, now on to install a few more programs (freecad maybe) for practice! I will remember to use code tags next time, sorry about that.
