Vapier vom Gentoo Dev Team bietet in seiner Patchsammlung fuer die coreutils den 001_all_coreutils-gen-progress-bar.patch Patch an.
Durch das einspielen des Patches erhalten wir einen tollen Fortschrittsbalken bei den Befehlen cp und mv:
cp -g /mnt/etcbackup.zip ~/temp etcbackup.zip | 1% | 175 MiB | 122 KiB/s | ETA 00:24.03
Zu finden ist die ganze Patchsammlung hier:
http://dev.gentoo.org/~vapier/dist/coreutils-6.9-patches-1.2.tar.bz2
Was etwas unklar ist das Gentoo direkt beim Ebuild fuer die coreutils einige Patches verwendet jedoch gerade diesen loescht!
hihi, doch glatt vergessen wo ich das gefunden habe:
geekosphere.org
Ich verwende zur Zeit fuer kleinere sftp/ftp Geschichten lftp. Nun wollte ich “schnell” den upload limitieren damit das Surfen nicht zur Qual wird hierfuer fuehrt man einfach in lftp folgendes aus:
set limit-rate <download-rate>:<upload-rate>
Everybody who loves bash are welcome to use my bashrc :)

Ich hab mir gedacht eigentlich ist es doch toll ein paar mehr Statusinformationen in den vielen ttys wo man hat anzuzeigen. Also habe ich meine /etc/inittab etwas erweitert und zwar um folgende Zeilen:
# show a clock
9:2345:respawn:/usr/bin/nice -n 19 -- /usr/bin/klock >&/dev/tty9 </dev/tty9
# show the system load
10:2345:respawn:/usr/bin/nice -n 19 -- /usr/bin/tload -d 5 /dev/tty10
# show /var/log/allmessages with less
11:2345:respawn:/usr/bin/nice -n 19 -- /usr/bin/env LESSSECURE=1 /usr/bin/less -iMRS +F /var/log/messages >&/dev/tty11 </dev/tty11

Ich verwend jetzt schon seit einigen Monate CenterIM, jedoch hatte ich immer das Problem das es mir Sonderzeichen (wie ö/ü/ä/ß) nicht angezeigt oder sogar ganze Woerter verschluckt wurden.
Zum Beispiel:
‘Österreich’ => ‘terreich’
Das erleichtert natuerlich nicht gerade das Lesen von Chatnachrichten, nun das Problem laesst sich jedoch recht einfach loesen.
Man hat bei der locale z.B. UTF-8 Support eingestellt (wie ich auch), leider sendet ICQ aber ISO-Bullshit.
Nun erst einmal rausfinden welche locale man eingestellt hat:
% locale LANG=en_US.utf8 LC_ALL=en_US.utf8
Nun wechselt man in die CenterIM config options dort gibt es die Einstellmoeglichkeiten Remote charset und Local charset, tja und die stellt man jetzt einfach nach seinen wuenschen ein. Bei mir waere das:
Tada und schon funktionieren bei mir die Umlaute :-)
If you have a document thats full of spaces or empty lines, edit it with Vim:
Eliminate empty lines:
:v/\S/dEliminate spaces at the beginning of each line:
:%s/^\s\+//Eliminate spaces at the end of the each line:
:%s/\s\+$//Hi there,
