We're not talking complicated stuff here - we're talking basics - atleast at the moment ...
Note I use ubuntu breezy badger distribution - the advice below may be transferable to other OS - please let me know.
find a file on your hard drive
To find a file on your hard drive type the following command replacing file-name with the name of the file you are looking for.
find out the size of a folder
To find out the size of a folder type the following command (replacing folder name with the name of the folder you want to know the size of):
du hs folder-name
unzip a file
If you want to see and use the contents of a file which you have zipped up you need to unzip it.
This will unzip the contents of photos.zip into the current folder.
use a USB stick
These USB sticks are the ultimate christmas stocking filler and easy to use in linux and windows.
In a terminal type
This will bring up a list of things to do with connections being made to your computer.
Look for something along the lines of
[4305409.365000] Attached scsi removable disk sdd at scsi7, channel 0, id 0, lun 1
It is the sdd part you are interested in (it might be sda, sdb, sdc ...)
Next create a drive that you will mount the usb stick to
Mount your usb stick to the drive called stick
sudo mount -t vfat /dev/sdd1 /mnt/stick
sudo does the comand as root
mount is the comand to mount the device
-t is for the type of file system which is vfat
/dev/sdd1 is where the device is note that this is the info we got from the dmesg comand, note that 1 has been added onto the end
/mnt/stick is the directory you mount the device to
You can then use the usb stick as you would any other mounted device ie.
will list all the files/directories on your usb stick
note that you will probably require sudo infront of these comands as you mounted it as root so only root has permissions to do things with it
Once you are finished unmount the usb stick with this comand
sudo umount /mnt/stick
zip a file
Zip = making files smaller, getting rid of all the extra random space that some files take up so you can squish more onto your disc
in your terminal type:
zip theNameOfTheResultingZipFile.zip theNamesOfTheFilesToZip
zip photosjanuary.zip *.jpg
top tip: the star is a wild card, it means all of the files in this folder which end in .jpg Time saver!!
Remember if you are trying to copy folders into your zip you need to add a -r to the command.
zip -r photos.zip photofolder/*
