View 5 Replies View RelatedI just recently reinstalled openSUSE 11.3 last night with the GNOME desktop. Since I'm starting fresh again, I'd like to set up my System as flawless as possible.
So, my question is stated in the Title. How do you set System-Wide environment variables on OpenSUSE 11.3 // GNOME? I usually set them by adding an export to my ~/.bashrc, but I remember in Ubuntu that I could add them to /etc/environment. I checked that file out on my system, and it has a the default comment on it stating:
"This file is parsed by pam_env module...Syntax: simple "KEY=VAL" pairs on seperate lines"
This seems to be the spot to add my "export JAVA_HOME=/usr/java/..etc", etc. but I wanted to clarify before I went ahead and made any changes.

I just migrated to Ubuntu 10.04 from windows and I could not be more satisfied, except for one minor, nitpicky detail. In iTunes I was able to sort my music by "album by year". That is, my music was sorted primarily by artist, then by album year. So each artist had their albums listed in chronological order. My library is meticulously tagged, so every track on every album is tagged with the same YEAR value. Is this possible in Rhythmbox? Is there a plugin or will i have to edit a .conf file (or similar) somewhere? I'm new to Ubuntu, but not afraid of getting my hands a bit dirty, so to speak.

I have a file that stores employee login IDs, names, types, and permissions. Our software reads the information based on byte-columns, so it reads a column as any ASCII character (spaces, letters, numbers, punctuation, etc.).

However, if I am creating the files from the MySQL output, I need a way to write to specific column locations in the file ...

View 5 Replies View Relatedstandard Linux installation utilities split the root file-system and the home file-system on two separate but relatively equal-sized partitions? For example, when I put fedora on an 80GB disk, it automatically gave the root file-system 32GB and home 30GB and the swap 8GB of space. However, since my home file-system has a directory with 28GB of files in it, why is my root file-system reading 100% usage? Is the home FS overlaid on top of the root FS? Is there an advantage to doing this? I just made a boot partition (50mb or so), a root partition (90% of the disk space) and a swap (4%-5% disk space).
