In addition to the ASCII-based terminal emulators discussed here,
most X installations also include x3270, which is an IBM EBCDICbased
terminal emulator that is used with mainframes. Another common
emulation is IBM 5250, which is also EBCDIC-based and is used
with IBM i-Series systems (formerly AS/400s).
As shown in Table 7-1, xterm, konsole, and gnome-terminal have similar commandline
options to set the terminal window name, the TERM variable value, and the program
to be executed on the terminal-interface side (the default is the $SHELL). These
programs may be extensively customized using resources (in the case of xterm) or
named settings profiles (in the case of gnome-terminal and konsole).

These three commands all run vi in a terminal window with the title set to Vi Editor:
$ xterm -T "Vi Editor" -e vi
$ gnome-terminal -t "Vi Editor" -e vi
$ konsole -T "Vi Editor" -e vi
Note that the window title can be changed by emitting a control code sequence.
