fortune when I start a terminal!?

Kris · 2006-08-27 16:47:29

Hey!

How do I do so I run a fortune quote when my urxvt term opens? I have seen this on for example Smoons desktops And it looks very nice

smoon · 2006-08-27 17:15:28

I've got the following at the end of my .zshrc:

if which fortune &> /dev/null ; then
    echo "e[1;31m`fortune`e[0m"
    echo ""
fi

It checks if fortune (the program to show the quotes; package to install is fortune-mod) is in $PATH and just echos it's output if found.

echo "`fortune`"

will work just fine if fortune is installed. This should work in a .bashrc as well.

chrismortimore · 2006-08-27 17:25:34

Can't you just do

`which fortune`

in .bashrc? If it finds fortune, it runs it. If it doesn't, nothing gets outputted.

thats just exactly what the little if-script does, just leave out the zsh parts so it looks lie this

if which fortune &> /dev/null ; then
  echo "`fortune`"
  echo ""
fi

^-- checks if fortune is present, and then 'starts' it

cheers,

Which mine does in two words, no if statement required

Plus you get a nice error message if fortune isn't found by which

If it finds <code>fortune</code>, it would not run it, but return its location. If it is not found, it would return an error message.

It works great - but I must use .bash_profile, .bashrc don't have effect...

I have seen that you - in the Show Your Desktop-thread - havde changed the default name/HOSTNAME-thing How do you make that?

If it finds <code>fortune</code>, it would not run it, but return its location. If it is not found, it would return an error message.

If you prefix it with an echo this is true. If you just run `which fortune` it will run the result of `which fortune' which is either the full path to fortune if found, or an error message if fortune isn't in $PATH - and honestly, running an error message is not the best idea

It's the environment variable PS1 in http://hg.nooms.de/dotfiles?f=0aebb8fe2 … yle=gitweb that is responsible for that.

Note the ` and the ` around the command, once it finds the command, it executes the string, as in the location of the executable.

Consider adding this check-up to avoid problems with some terms:

if [ $TERM != "dumb" ]; then `which fortune`; fi

Yeah, the PS1 stuff. The first one is red and looks like this
root@host:/pwd %
The secocnd one is blue and looks like
user:/pwd %

What terminals are "dumb" and why are they unable to print out text?

Hmm... I think that zsh gives a different output than BASH

Hmm, yeah. There are some differences in Bash (I forgot about that).

%{e[1;31m%} for zsh is [033[1;31m] in bash, whereas 033[ is the indicator for a following escape sequence (e[ should work as well), 1;31 is the colorcode (1 for bold and 31 for red; there's more like underline etc. which you can combine) and m to mark the end of the escape sequence. The [ and ] around that are to tell bash that the characters inside of these braces are not printed out, if you don't put the escape sequences in these bash will get confused about the length of your prompt. If you want to know more just search the intarweb, you'll find plenty of information about this topic there.

Edit: The %n, %m, etc. are different in Bash as well. For example %n is the current user in zsh, in Bash it is u. Have a look at the bash manpage to find out about the available backslash-escaped special characters, the topic is PROMPTING.

Like this? It give also a weird output
