Apr 18, 2010In Red Hat, suppose if root user wishes to give a privilege to run the fdisk command to a user named sam.And he makes appropriate configuration changes in /etc/sudoers file. Now when sam wishes to run the fdisk command, then he has to issue:
Code:
[sam@system43~]$sudo /sbin/fdisk -l
Password: But in ubuntu, after the same configuration being done, what sam needs to do is:
Code:
[sam@somesystem43~]$sudo fdisk -l
Password: ***
That means, in ubuntu the user need not type the full path of the command. I wish to know how can I make red hat system work like ubuntu as far as the sudo usage is concerned.

Mar 29, 2010I regularly use 'df -h' to check usage on each of my primary directories and mount points.
I'm currently somewhat confused by disk usage within my filesystem, so I'd like to do the following:
Display directory size of all, or say, the 10 largest, subdirectories to a specified directory. So, if I passed the root (/) directory, output would list the subdirectory of / with the largest disk usage first and its associated disk usage listed in human readable format (either M or G suffix as appropriate), followed by the subdirectory and usage for the second largest directory and so on.
Can anyone suggest a command or series of commands to do this?

Changing the file extension is easy since there are lot of examples for this.
But now I want to rename my files like this:
'somePrefix_blablabla.ext' --> '0_blablabla.ext'

I DON'T want an incrementation, just the leading prefix '0_'

Fedora :: Hidden Disk Space Usage \ Can't Figure Out Where The Runaway Usage Is?
Dec 10, 2010I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code:
[root@Zion ~]# df -h

Software :: Use "top" Command To Check The Resource Usage ?
Apr 28, 2010I usually use "top" command to check the resource usage , it is very good and simple method to know the status ( loading , CPU , memory usage ), but we have many servers so we can't check the servers frequently , so we can't find the problem before the problem happens
Any method / script that I can implement to send us a alert mail if the resource usage reach a specific level , for example , if the CPU usage reach 90% , then send us a alert mail.

General :: CPU Usage Of Process
Jul 15, 2011I am currently writing a JAVA script to monitor certain unix processes through JConsole. Upon having lots of trouble with runtime.exec, i decided to bypass the top/ps command call and just get the information straight from /proc/*pid*/whatever.Now i can pull back any information from any of the files I want, and the current way i determine the CPU usage of a process is as follows:Add the UTime and STime of that process from /proc/pid/stat then divide my pidCpu by UTime + STime + NTime from /proc/stat, then multiply that by 100, should give me the % cpu usage a process is using, right?Theory being if I get the jiffies assigned to my process, I can divide that by the total jiffies the cpu assigns.
However, my results seem to vary from the ones gathered from top and ps. What am I doing wrong?

General :: How To Check Ram Usage
Jan 4, 2010I am running Slackware 13.0. I am aware of free -m, vmstat, top, etc. However, none of these programs display how much ram each program is using. Is there a program that displays how much ram each program is using? I run a headless so I'd need a program that runs in CLI.
I know that top command shows %MEM (only two programs were using 0.1%MEM) but after running free -m I only have a total of 400 MB ram left out of my 1.5 GB of ram. Where is all that lost ram?
