The xterm command launches a terminal-emulation window under X. It essentially gives you access to a Linux command line via a window, and as such is probably the most-used X command in Linux.
OPTIONS
There are many options to xterm, including one that controls columns in obscure terminal emulations. Here, we’ll cover the major options; check the online-manual pages for a more detailed listing of options.
| -ah | Always highlights the text cursor. |
| +ah | Highlights the text cursor if it’s over the window with focus. |
| -aw | Turns on auto-wraparound. |
| -b number | Sets the size of the inner border (the distance between the outer edge of characters and the window border) in pixels. The default is 2. |
| -cr colorb | Sets the color for the text cursor. |
| -e program args | Runs program in the xterm window. This option must appear last in the command line. |
| -fb font | Sets the font for the bold text. |
| -j | Sets jump scrolling, where multiple lines can be scrolled at a time. |
| -ls | Sets the shell started in the xterm window as a login shell. |
| -mc milliseconds | Sets the maximum time between multiclick selections. |
| -ms color | Sets the color for the pointer cursor. |

| -sb | Saves scrolled lines and displays a scrollbar. |
| -sl number | Sets the number of lines to save that have been scrolled off the top of the screen. The default is 64. |
| -tm string | Sets terminal setting keywords and the characters bound to those functions. Keywords are: intr, quit, erase, kill, eof, eol, swtch, start, stop, brk, susp, dsusp, rprnt, flush, weras, and lnext. |
| -tn name | Sets the terminal type in the TERM environment variable. |
