The default Emacs on Mac OS X, 22.1, appears to have some problems with the info/help stuff.
When you hit C+h i, it says:
Can't find the Info directory node.
It works in AquaEmacs, but I downloaded the 23 version of emacs precompiled binaries from here and I still have the same problem.
I've set up DRBD on 2 machines, 1 of them is the master, another is the slave.
After each bootup, I need to run the following on the master machine:
Code:
drbdadm -- --overwrite-data-of-peer primary all
Do we need to specify which machine should be the primary node every time? Is there any method to make the machine "know" it's itself the primary node?
I would like to delete a directory in emacs' dired-mode.
I mark the directory with the "d" key, and then hit "x" to deleted flagged.
I then get the following error:
Is there any way to get emacs to delete the directory and stop its whining?
I want get the information from a directory full of files.
What I have so far is this:
Code:
find <path> -exec head {} ; | tail -2
My question is, how do I get that certain section from each file, since tail will only affect the last file. I've tried piping head and tail to sh but that's not available due to permissions.
I've bought an X10 Home Automation USB interface: the CM15.
This is the information lsusb gives:

But this tells me nothing about where the device file is! How can I find that, or create one myself?
Where can I find comprehensive information on optimizing Linux? I keep searching online but seem to get only to performance monitoring. I don't want to run a lighter version of Linux or upgrade my hardware! Just want to get my current distro and future ones I might install to run at its best.

View 6 Replies View RelatedBack in the old days of PC-DOS 3.1, computers are much simpler than today's. I can learn a lot of how File System works with tools like PCTools, Norton Disk Doctor, and [URL]. Have been working exclusive in corporate database application area for over a decade, my knowledge of how these stuff work is diminishing. Standard-clean OS (Windows, Linux) installation is all I can do now. And it starts to cause me many data-loss troubles, when I have to perform something that I don't have much insight, such as install and remove peer linux os or move and resize partitions.
I'm looking for books, web resources, or communities where I can educate myself on how various file system works, for which I can have in-depth answer to questions such as:
How to remove ubuntu and grub2 ? (I recently did that, but with a lot of frustration when I was not really sure what I was doing and confront with some scary error message like "Missing BootMgr" What kind of disk-partitioning operation can be performed non-destructively, and why ? What is Active partition ? Primary Parition ? Extended Partition ? How it stored on the disk. There are many free partitioning tools out there, which one is safe to used ? NTFS, Ext3, Ext4, .. What the differences ? How to choose it wisely.

View 1 Replies View RelatedI'm quite new to linux but I have configured a simple ftp server and it's working great. I have a FTP-Shared folder with upload and download subfolders. Under upload's and download's I have identical category subfolders like mp3's, movies, software etc. in both. As the guy's upload, I would like to create a line crontab where I can move all the content under /FTP-Shared/upload/mp3/* older than 14 day's to FTP-Shared/downloads/mp3/ recursively (Like in cp command), but the timestamp must be searched on the first directory and not sub files example: /mp3/Club Dance/CD1/Hallo world.mp3This is how far I got:[root@clients ~]# /usr/bin/find /FTP_Shared/upload/Mp3s/ -depth -mindepth 1 -mtime +14 -type d -exec mv -f {} /FTP_Shared/download/Mp3s/ ;This command moves the directory and files, but it is not recursively
View 4 Replies View RelatedI have created a simple menu driven script for our Operations to take care of the basic monitoring and managing of our production application from the back-end. Now, the script when tested in UAT environment was fine, but when deployed to production it kind of behaved oddly.hen the Operator chooses an option from the menu he is given the output and at the end is prompted to return to the main menu by using ctrl+c. In production, this return does not occur for some strange reason and the program just sits there.The session becomes unresponsive after that and I'm forced to terminated it by closing the PuTTY.I tried enabling the debug mode too (set -x) and still was not able to find any useful hints/trails as to why.

View 3 Replies View RelatedI am familiar with windows 2008 cluster servers, and I just started testing with centos cluster. I am creating a simple 2-node cluster, for a simple ping test.
Node 1: 10.0.0.1
Node 2: 10.0.0.1
Virtual ip: 10.0.0.10
So far, I can ping a virtual ip, and manually relocate it between the nodes, but I didn't figure out, how to do this automatically. So this is my question: How can I setup the cluster, to it automatically failover the a service to another node case one node fails?
I need to write a script to report useful information on disk utilization for each user's home directory.For each directory I need to show: 1. the long listing of that directory entry (but not the files in the directory), so that I can see the rights and owners of the directory.2. The amount of disk used by that directory, in human-readable format, including subdirectories. I need to have two lines for each user one after the other. For example:
/home/user1 directory info
/home/user1 disk usage
/home/user2 directory info
/home/user2 disk usage
The script will assume that all users, except user root, have their home directories in the /home directory (no need to do anything with the /etc/passwd file). And if the administrator adds or removes users, the script should still work correctly (so the script shows the information for all current users).
Here's what I do know. The command "ls -ld /home/user's_name" will give me the info I need for #1. And the command "du -hs" will give me the info I need for #2. What I don't know is how to grab each individual directory in order to apply the above commands to each of them in order. ???
I don't have much experience in clustering. And I'm deploying a cluster system on CentOS.But I don't know how long a node failover and another node take over those resouces to continue running service is good, fast or slow? 1s, 10s or
