I am trying to install the video editor cinelerra but the install file is (.txz). I've been looking and I can only find things that explain how to install .tgz or .tar.xz files and such. Could anyone help me with this?
Edit: I now have it installed, when I try to run it, it doesn't do anything. I'm going to try rebooting then I'll add another edit.
.txz is short for .tar.xz, just as .tgz is short for .tar.gz. You can unpack it like a .tar.xz archive:
Run tar xf *archive*.txz, since tar will automatically figure out how an archive is compressed and decompress accordingly.
Assuming you downloaded this file (or that one), linked to from here and listed under "Ubuntu 14," there are a few points to keep in mind:
Most archives for software kindly keep everything in a top-level folder, but this one doesn't! Therefore, I suggest creating a cinelerra folder, putting the archive in the folder (or downloading it to there in the first place, if you haven't already), and unpacking it there:
mkdir cinelerra
cd cinelerra
wget http://cinelerra.org/2015/downloads/cinelerra-4.6.mod-ubuntu-14.04.1-x86_64.txz
tar xf cinelerra-4.6.mod-ubuntu-14.04.1-x86_64.txz
Generic instructions for installing software from compressed tar archives are often instructions for installing from source, as source code is commonly packaged this way. However, Cinelerra is distributed for Ubuntu as a precompiled binary in a compressed tar archive. Thus, as the README file says:
Run `./cinelerra` from this directory. That's it.
A .tgz or a .tar.xz file is not an installer, but a compressed tar archive. You need to decompress and to extract the archive to access the files inside it:
Terminal by hitting Ctrl+Alt+tHome named extracted_files run the following command: mkdir ~/extracted_filestar xf <.tgz_.tar.xz_file_path> -C ~/extracted_files, where <.tgz_.tar.xz_file_path> is the path of the .tgz or .tar.xz file
