Can I increase the size of the command history in bash?Note that I use a Red Hat Linux computer in the undergraduate astrophysics department here (so I don't get that many privileges).
Is there a maximum size to the bash history file?
bash;command history
Instead of specifying numbers, you can dounset HISTSIZE unset HISTFILESIZEshopt -s histappendin which case only your disk size (and your largest file limit, if your OS or FS has one) is the limit.However, be aware that this will eventually slow down bash more and more.  see here and here for better ways.
