Hi!
Ich will die Variable PATH ändern.
Das ist leicht. Ich schreibe nur die Kommando:
$ PATH=$PATH:/usr/local/pgsql/bin
Jetzt habe ich die Variable geändert genau so wie ich will,
aber nach dem neustarten des PCs ist diese Änderung verlohren
gegangen Kann mir jemmand sagen was ich tun kann?

Zitat von Usher

Du machst die Änderung einfach in der Datei .bash_profile vom jeweiligen User. Diese Datei findest Du im Home-Verzeichnis des Users. Jedes Mal, wenn Du dich dann als der entsprechende User einloggst, werden die Befehle darin ausgeführt.

nach den ausführung der kommando "ls -lA" in /home/username
finde ich nur das Datei .bash_history

Zitat von Kampi

andere möglichkeit ist auch noch die '.profile', dort gehoerts aber nicht wirklich hin.
gut ist auch '.bashrc' oder eben die globale '/etc/bash/bashrc'.

'/etc/bash/bashrc' - das habe ich nicht
'.bashrc' - wo kann ich das finden?

ich habe 'etc/bash.bashrc' meinst du das vielleicht?

Ich find's überhaubt nicht, wo das Variable PATH ist

Hier ist der File

# /etc/bash.bashrc for SuSE Linux

# will be lost during system upgrades. Instead use /etc/bash.bashrc.local
# for your local settings, favourite global aliases, VISUAL and EDITOR
# variables, etc ...

dude thx for help
all works perfect

Zitat von michi204

noch ein appendix: ich fand es immer ganz praktisch, dass man in der bash (temporäre) umbebungsvariablen für einzelne programme einfach vor den aufruf setzen kann, zB:

Code

LC_ALL=C mozilla-firefox &

lg michi

kannst du das ein bisshen mehr erkleren?
ich kapiere nicht ganz, was du mit dem kommando meinst?
