I have benn using ubuntu on an old laptop to run a samba server and a torrent server and it has been working fine till a few days ago when it stopped letting me write any files to the disk, So i tried deleting some of the files i no longer needed to free up some space and the disk usage didnt decrease so i checked it out using the disk usage analyzer and it says its full but i know for sure its not.

View 3 Replies View RelatedI've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
Code:
[root@server1 ~]# free -m
total used free shared buffers cached
Mem: 12011 7946 4065 0 4 23
-/+ buffers/cache: 7919 4092

I have installed Centos in my server and when I take, top -c command its not showing the "command" option correctly. Due to the same, I'm not able to correctly track down the file which causes excessive usage. For eg:
top - 09:30:29 up 72 days, 12:46, 2 users, load average: 0.21, 0.16, 0.15
Tasks: 122 total, 1 running, 120 sleeping, 0 stopped, 1 zombie
Cpu(s): 4.8%us, 0.7%sy, 0.0%ni, 93.5%id, 1.0%wa, 0.0%hi, 0.0%si, 0.0%st
[code]....
Does top command find out cpu time and process time for an interval and then calculates the process's cpu usage
eg: process time(interval 5sec)/cpu time (interval 5 sec)*100 %

Im using the top command and can get a list of all the cpu usage for all the process but cant only get the processes with 10% or more. I'd want these processes sent to a new file. Would I be able to cat the cpu usages and PID into a file?

The command time shows the time taken by a command to complete. Is there a command that shows the change in disk usage caused by a command? I would like to know how large a package is when I install it from source.

View 5 Replies View RelatedIn 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.
is there a command that shows current network usage, similar to the way htop shows memory and processor usage?

I got my disk usage. Now using my host server Im going to check the server 66.50.100.3 disk usage. Is its possible to check the disk usage of 66.50.100.3 using my host server?
View 4 Replies View RelatedI 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?
When at the console, what is the command (if there is one) to determine memory usage (used/free) on the hard drive that is being used for one's OS?

View 5 Replies View RelatedI want to rename some files in one directory and found the command 'rename' most appropriate.
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'
'somePrefix_blablablablabla.ext' --> '0_blablablablabla.ext'
I DON'T want an incrementation, just the leading prefix '0_'
correct perl expression syntax for this?

View 3 Replies View RelatedThis is an extremely weird issue that I can't find any help with on Google. It is minor but extremely annoying.
When I type in a linux command in the terminal, (e.g. "ls -la"), and then press enter, the cursor goes to the next line and just sits there, as if its processing some long command.
If I press enter again, I see the ls output as well as my prompt twice. It's like the terminal window isn't auto-scrolling, but I've also seen this happen when there wasnt even enough text in the console screen to warrant a scrollbar. Has anyone seen this before and know what I need to do? I hope what I'm asking about makes sense.
