"BOLD" printing a variable in PS1 command
I would like to "BOLD" print the hostname in the following statement:
export PS1=$USER"@"$(hostname -s):'$PWD>' Is there a special character I can put before and after the variable to make it bold or blinking? Thanks. |

That's pretty much the copy+paste answer, but it's in bash syntax, which may or may not work for you. In general, ANSI codes starting with esc [ and ending with m after some numbers work well, but they're not portable to all terminals. A (slightly) more portable solution would be to use tput Code:
PS1=$USER"@"$(tput bold)$(hostname -s)$(tput sgr0):'$PWD>' See the tput manual page for more information. Perhaps you will find that the codes output by tput are exactly equivalent to the hard-coded escape codes given above. In theory, tput should be portable to terminals which do not speak ANSI, but I don't know of a real-world situation where this would make an enormous difference. (The code \033 is octal for the escape character.) Last edited by era; 03-17-2008 at 03:00 PM.. |
