Software can installed locally for use by a single user or group, depending on the location of the install.

To install software for a single user, you will need to download the source code for the software using either wget or curl (most software will specify which).

The below example will install Git from source code:

cd ~/bin
## OR 
cd ~/home/group/<group_name>/software 
#If there is no software folder in your group folder, you will need to add this with: mkdir software

Once in the desired folder, you can download the Git source code using curl (this example uses Git version 2.26.2)

curl --output git.tar.gz https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.26.2.tar.gz

The source code will likely be compressed. To extract the zipped files, use the tar command:

tar -zxf git.tar.gz

Go to the newly extracted folder. Inspect and README or INSTALL files. These will contain useful information.

Execute the configure script, which will create make files and configurations for the software that you are about to compile and install. Then make and install the software.

cd git-2.26.2
./configure
make
make install

This process may take some time.

Finally, add new software  to your path. To update your path, source your bashrc file:

export PATH="$PATH:$HOME/bin/git-2.26.2"
