Ubuntu – How to run Disk Utility in terminal via a comand line

command linedisk-utility

First of all, I must say that I have successfully used Disk Utility in the past and thus I could rename my partitions.

But yesterday, I saw that my partitions are not mounted, so I used Storage Device Manager to make them to automatically mount at start up. That was a success also but I saw that the partitions are labelled as sda1 and sda7 not as they were initially. So I wonted to open again Disk Utility to rename them.

The problem is that, no matter how many times I try to open the application it just does't start at all! I don't know why it is doing this, as I have already told, I could use it in the past very well. I don't know if this "lack of reaction" of the application is the result of the actions I described before, or it is something else.

But I'm thinking of trying to start Disk Utility in terminal. Maybe I'll force it to run and solve the labelling problem. Do you have any ideas?

The application behind "Disk Uitility" changed in newer release versions. Hence the terminal command to call them is as follows:

For >= 12.10

gnome-disks

For earlier versions including 12.04:

palimpsest

Renaming partitions can also be done with a command line tool (no need to install and run gparted):

Please note that the device and partition names /sda, resp. /sda1 ... /sdaX and /sdb /sdc .. do not depend on the disk label but are internal device numbers, depending on partition layout, SATA-port attachment, BIOS. To avoid confusion we have a unique UUID for each drive to mount it appropriately. This can be replaced by a label if needed.

Ubuntu – EOG (Image Viewer) fails to open gif files with incorrect png extension – how can I solve this

If you use (from command line or within a script... if you need the script just ask ;) ) the command file thisimage.png, it will tell you what image format you actually have.... Then you can rename accordingly...

This is a sample of what I get with a file with incorrect file extension .png which is really a jpg file:

user@computer:$ file logo.png
logo.png: JPEG image data, JFIF standard 1.01

Edit: Oh, ok, I was lazy before... Here's an script that will rename actual gif files that are named with .png extension to their correct extension .gif:

#!/bin/bash
for NAME in $(ls *.png); do

if [ "$(file $NAME|grep GIF)" ]; then

echo "Renaming ${NAME} to ${NAME%.*}.gif"
mv ${NAME} ${NAME%.*}.gif

fi

done

Ubuntu – How to refresh Disk Utility

The kernel probably doesn't know about the change. A good tool which helps in this case is partprobe. Just call it with sudo partprobe. The software will test all drives and if it finds new partitions it informs the kernel. After a successful run you'll see your image instead of free space.
