Manually customize bash terminal prompt look
The prompt text that bash interprets and uses is set with the PS1 environment variable and is usually specified in ~/.bashrc. I have been manually tweaking my bash prompt look and feel to make some of my work project use-case tasks easier. The combination of default style changes, and specific prompt elements added for active environment or sourced environments should make terminal-based project management a little easier. A little searching allowed me to discover this website that allows you to interactively customize the prompt contents and style with common components. https://bash-prompt-generator.org/

An Update To Apptainer Use On TACC HPC
The University of Texas’ newest supercomputer Frontera currently requires the following modules loaded for Apptainer images/containers based on the mvapich infiniband (ib) base images–particularly for any containerized programs that intend to use MPI. Researchers moving their Apptainer images between TACC HPC systems, or building container images specifically for individual systems, may need to adapt their sbatch scripts to accommodate differences between default environments and infrastructures on the various available clusters.
