Samtools is a very useful tool for manipulating and visualizing .bam files. Here is a quick guide on how to install Samtools. First download the most current version from the Samtools website. Unzip the file using either tar xvjf or the extract command. Go into the newly created directory and compile the code by typing "make". Your code should look something like this.
The next step is then to modify your .bashrc file so that when you type "samtools" it calls the program. To do this open your .bashrc file and add the following line of code, where directory is equal to the directory that you have installed Samtools in.
Make sure as a final step to source the .bashrc file by entering source .bashrc into the command line.
