The default shell in Redhat has been bash for as long as I've used it.
The history will be found in /home/username/.bash_history by default. One thing that bash does, though, is saves the command history in memory, not writing to the .bash_history file until the user ends that session.
Redhat (probably, other Linux variants have it as well) does have a few good monitoring utilities available, though. Check the man page on "ttysnoop", and man "vcs". You can get a screenshot of a terminal by simply using cat. For example:
cat /dev/vcs0 > /root/tty0_log
more /root/tty0_log

ul
UL(1) BSD General Commands Manual UL(1)
NAME
ul -- do underlining
SYNOPSIS
ul [-i] [-t terminal] [name ...]
DESCRIPTION
The ul utility reads the named files (or standard input if none are given) and translates occurrences of underscores to the sequence which
indicates underlining for the terminal in use, as specified by the environment variable TERM. The file /etc/termcap is read to determine the
appropriate sequences for underlining. If the terminal is incapable of underlining, but is capable of a standout mode then that is used
instead. If the terminal can overstrike, or handles underlining automatically, ul degenerates to cat(1). If the terminal cannot underline,
underlining is ignored.
The following options are available:
-i Underlining is indicated by a separate line containing appropriate dashes `-'; this is useful when you want to look at the underlin-
ing which is present in an nroff output stream on a crt-terminal.
-t terminal
Overrides the terminal type specified in the environment with terminal.
ENVIRONMENT
The following environment variable is used:
TERM The TERM variable is used to relate a tty device with its device capability description (see termcap(5)). TERM is set at login time,
either by the default terminal type specified in /etc/ttys or as set during the login process by the user in their login file (see
environ(7)).
SEE ALSO
colcrt(1), man(1), nroff(1)
BUGS
The nroff(1) command usually outputs a series of backspaces and underlines intermixed with the text to indicate underlining. No attempt is
made to optimize the backward motion.
HISTORY
The ul command appeared in 3.0BSD.
