So what is /usr/bin/[ command for? I just noticed it on my system. It's part of the coreutils.x86_64 package. I can't find a man page or anything in /usr/share/docs. It's also very hard to google search for /usr/bin/[
View 8 RepliesI 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

Anyone know why my fresh installation of centOS server is so slow? Seems like it takes over a minute to execute a command, im not doing anything complicated either. Secondly, how come at times when I type reboot the machine starts to beep, one long loud annoying beep.
View 5 Replies View RelatedSo on a fresh install on CentOS 5.3 I can't seem to run any command.For example if I try to run "fdisk" I get a "command not found error. Now if I add "/sbin" the the front of the command like "/sbin/fdisk" It runs. So what would be the fix for this. It is kinda annoying to add sbin to the front of every command.

View 1 Replies View RelatedThis is an (apparently) very simple question: I would like to execute a command upon bootup of my system. It is a hardware related command which echoes a parameter into a sysfs file.
I thought the proper place for such a command would be /etc/rc.d/rc.local. But it does not work, the command seems to be ignored (no idea why...) :(
Does rc.local require special syntax after all? Or is there a better way to specify bootup commands? Ok, I could create a standard init script, but it is not really a service which has to be started/stopped/restarted..
I have tried every variation I can think of to get an 'at' to rm a file after a certain amount of time.
echo 'rm -f /var/www/media/images/tempProducts/XYZ.png' | at now + 2 minutes
In php:
$apCommand = "echo 'rm -f " . $sTempName . "' | at now + 2 minutes";
exec ($apCommand);
I have:
- pasted the command into the command line as root and it works fine so it seems to be rights related -- rm gets scheduled and the file gets deleted after 2 minutes
- tried every variation of sudo within the statement including making sure that apache is listed in sudoers
- chmod to 777
- chown to apache
The rm command does get scheduled into the 'at' queue but the rm never removes the file.
at -c (without adding sudo to the 'at' statement)
#!/bin/sh
# atrun uid=48 gid=48
# mail apache 0
umask 22

View 2 Replies View RelatedThe normal distros now ship with an executable called "timeout". Will CentOS be including this new "timeout" command in an upcoming release?
I read that CentOS did not include it (yet) because of a name conflict with another package.
For some reason every time I enter the 'login' command as root, my putty shell craps out. It's as if the kernel is not prepared or does not know how to handle the 'login' command. Where can I set it up? Maybe it's not configured to use PAM?
I want to use this command to switch users. Sure I can use 'su username' but I noticed there are some issues when using 'mail' command right after I change users. It gives me a permissions error as if the environment variable for mail is set for roots mailbox instead of the new users mailbox.
How can I configure 'login' to work properly in CentOS?
how can i get qmake command working on my centos, if possible provide the link to download it.
View 6 Replies View RelatedI'm running into what is quite possibly one of the strangest problems I've ever encountered. We recently had a power loss, and some of our vmware instances didn't shut down correctly. Once of those is our Zabbix testing monitor. From that point on, whenever I run the "ll" command, my terminal freezes. This happens over both ssh and the local console. I've forced a disk check via the "shutdown -rF now" command, and it returned no errors. Since ll is simply an alias for ls, I copied ls (and the entire bin directory) from another Centos 5.3 instance, with no change in behavior.

View 1 Replies View RelatedThe last time I did a restore using cpio under CentOS 3.9 it took a very long time for me to find my seemingly correct command wasn't working and I ended up doing the work in Knoppix.
