[gentoo-user] Have portage lost its memory?
Hi, Todays emerge --sync emerge -vauDN world made me wonder a lot. A lot of packages should be updated according to portage, but a lot of them seems to be wrong with regard to the reported version number. Take e.g. Evolution of which I have version 2.4.2.1 installed. Portage is saying that I have version 2.2.3-r3 installed and that I should update to 2.4.2.1: [ebuild U ] mail-client/evolution-2.4.2.1 [2.2.3-r3] +crypt -dbus -debug -doc +gstreamer +ipv6 -kerberos -krb4 -ldap -mono -nntp -pda -profile +spell +ssl 11,233 kB So what exactly is going on here? Thanks, jules -- gentoo-user@gentoo.org mailing list

Here is an example that you could put in your .bashrc:
# Is this an ssh connection?
if [[ ! -z ${SSH_TTY} ]]; then
# Set prompt to \green([EMAIL PROTECTED]) \blue($PWD \$) green(..
PS1='\[\033[01;[EMAIL PROTECTED] \[\033[01;34m\]\w \$ \[\033[01;32m\]'
# Not an ssh connection
else
# Set prompt to \green([EMAIL PROTECTED]) \blue($PWD \$) black(..
PS1='\[\033[01;[EMAIL PROTECTED] \[\033[01;34m\]\w \$ \[\033[00m\]'
fi
If you want other colors or whatever refer to man console_codes.

Re: [gentoo-user] Have portage lost its memory?
Selon Toby 'qubit' Cubitt [EMAIL PROTECTED]: I used to give the shell prompts different colours on different machines to help avoid this. Or rather, the local one would always be the same colour, but shells under ssh sessions were colour-coded by machine. I've lost the script I wrote for this somewhere in the mists of time (if I remember right, it was copied and hacked from a bash prompt example that colour-coded according to the login type: ssh, telnet, local, etc.) Here's one I use to make a difference between root (red prompt) and user (green). As for other stations, their prompt stays white. Hope it can help : [ $UID -eq 0 ] PS1=\e[1;[EMAIL PROTECTED] : \W \! # \e[0m || PS1=\e[1;[EMAIL PROTECTED] : \W \! $ \e[0m More readable version if test $UID = 0 ; then PS1=\e[31m\h:\w # \e[0m else PS1=[EMAIL PROTECTED]:\w \!\e[0m fi -- gentoo-user@gentoo.org mailing list

Here you go. It also checks if you're root. Save it as something
suitable somewhere in your $PATH, (e.g. ~/bin/bash_prompt), modify to
suit your setup, then do:
source ~/bin/bash_prompt
colour_code_prompt
unset colour_code_prompt
either from the shell or in your .bashrc to load it.
Use at your own risk, since I've only just written it, and haven't
tested it very heavily! (When I've used it a bit to check it works
properly, I might document it a bit and put it on my web site.)
