Tools like iostat, vmstat and alike offer to run in intervals.

iostat [options] 15 240 > /mypath/iostat_$(date "+%Y%m%d%H%M") will run iostat every 15 seconds 240 times, total of one hour, and...

Consider putting iostat, vmstat, mpstat in short intervals in file (like 15 seconds, every hour new file [15 240]). Be sure to take notice of disk space required.

Yes... in the early days folk's DNS servers were almost always recursive which meant you could use them as your general purpose DNS. But obviously, that could cause problems so usually your server...

The act of domain registration and authoritative holder of DNS for that domain are separate things. When you have registered a domain normally some DNS is given authority or some means by which you...

Think of nameservers as something different (but not necessarily) from your domain.

I have seen rpm's that rename a conflicting config file to .rpmsave or rename the new file to .rpmnew.
But not every rpm is nice like that.

Before you run yum update, you need to protect yourself by saving a copy of your custom configuration files.

Did you consider trying setfont Uni2-TerminusBold20x10.psf.gz or similar?

Can you check with mount command then if exit code is 0 do the rsync, else don't rsync ?
Touching a file will work on both directory and mountpoint so that check is not good.

While the backup filesystem is unmounted, can't you do a chmod 0 /mnt/mybackup? That should prevent accidental syncing when the backup filesystem is unmounted.

When you mount a filesystem on that...

Hi,

I used to use this type of check when I used external devices.

PARCHK=`df -k | grep mybackup | wc -l`

if [ ${PARCHK} -ne 1 ]
then
echo "The portable hard drive...

Could you create a subdirectory on the external drive and write to that? In this case, a write with the filesystem not mounted would get a "target not found" or equivalent message. It would mean...

Also, since you passed --directory=/, the dot refers to all subdirs within that directory, except those you excluded.

The tar output file also stores the file names (and permissions) you give it so it knows how to restore them, just as Winzip and other tools do. If you give it a name starting with /, then that...

You can easily post code here by using code tags, stuff[/code].

If you wanted to compile unmodified UNIX code under Windows you could use cygwin.

Xwindows is usually based on the ncurses library. See what your manual page for ncurses shows you.

This is a good how-to document:

When you edit grub.conf to add another boot option, you will have to re-build the stage-2 GRUB loader; which is why is a necessary step.

The GRUB stage-1 is just a 512 bytes system boot loader...
