I've come up with a little something you can do with dd and SoX if you're really bored and can't think of anything else to do:

Code:

$ dd if=<whatever file here> of=<whatever output file here> bs=<1024/512>k skip=<# of MiB to skip through the file (or in increments of 0.5 MiB if you supplied 512k as the block size)> count=<MiB of content (or in increments of 0.5 MiB)>
$ play -q -t raw -s -b 16 -v 0.03125 -c 2 -r 48k <output file from dd>

...

Slackware-13.1-Hacks-Emptying trash files

Posted 01-01-2011 at 11:10 PM by arniekat

These instructions are for deleting files that will not go away when you empty the trash using the icon on your desktop.

The trash files are kept in /home/<user_name>/.local/share/Trash/files

$ su
$ <Root_Password>

# cd /home/<user_name>/.local/share/Trash/files
# rm -rf /home/<user_name>/.local/share/Trash/files/files_that_wont_go_away

Slackware-13.1-Hacks-Changing System Time

Posted 01-01-2011 at 10:39 PM by arniekat

This will adjust your system time and correct it using a Stratum 2 Time Server. The quickest way to change your system time is to do the following:

$ su

$ <Root_Password>

# ntpdate pool.ntp.org

You should see confirmation that it worked. The second way of doing this (in case the first way did not work) is to get the IPV4 address or hostname of a Local (meaning in your time zone) Stratum 2 Time Server from the following website:...

Slackware-13.1-Hacks-Mount ISO Image

Posted 01-01-2011 at 10:18 PM by arniekat

Suppose you have an ISO Image of a CD/DVD and you want/need to get some information off the disc image. You can mount it as a filesystem and use your file browser to see its contents.

Create a directory to mount the ISO Image:

$ su
$ <Root_Password>
# mkdir -p /mnt/disk

Now mount the *.iso file system to the mount point:

# mount -o loop /<Path_To_ISO_Image>/<Name_of_ISO>.iso /mnt/disk
# cd /mnt/disk...

Slackware-13.1-Hacks-Emptying tmp

Posted 01-01-2011 at 10:09 PM by arniekat

# This will empty the /tmp folder when you shutdown or
# reboot the machine
# Add this line to /etc/rc.d/rc.6

echo "Emptying /tmp"
rm /tmp/* -rf &1>2 > /dev/null

The /dev/null part gets rid of any output/error codes.

I placed it between the following sections in /etc/rc.d/rc.6

# Save the system time to the hardware clock using hwclock --systohc.
if [ -x /sbin/hwclock ]; then
# Check...
