Run the following to see if your terminal support italics: |

Examples
Change the default window size:
- Add/Edit this line to file ~/.Xdefaults:
xterm*vt100.geometry:150x50+100+100
- Merge it in X database:
% xrdb -merge ~/.Xdefaults
- Configure xterm fonts, colors, size. Edit ~/.Xresources:
XTerm*foreground: rgb:00/00/00
XTerm*background: rgb:ff/ff/dd
Xterm*saveLines: 4096
xterm*faceName: DejaVu Sans Mono:size=12
xterm*VT100.geometry: 132x40
- ... then update X resource database:
xrdb ~/.Xresources

Terminals
List of terminals that support 24-bit true colors:
- Gnome-Terminal
- Gnome-Terminator
Test true-color support
Run the script[1]:
awk 'BEGIN{
s="/\\/\\/\\/\\/\\"; s=s s s s s s s s;
for (colnum = 0; colnum<77; colnum++) {
r = 255-(colnum*255/76);
g = (colnum*510/76);
b = (colnum*255/76);
if (g>255) g = 510-g;
printf "\033[48;2;%d;%d;%dm", r,g,b;
printf "\033[38;2;%d;%d;%dm", 255-r,255-g,255-b;
printf "%s\033[0m", substr(s,colnum+1,1);
}
printf "\n";
