To find files and folders not belonging to the user or the group of the user:

Code: Select all

find $HOME ! -user $USER -type f

find $HOME ! -group $USER -type f

( correction after with: sudo chown user:user /Myfolder/Myfile ... chown -R --> for recursive behavior))

Kwrite, part of the KDE Plasma application suite, can open all the log and text files which have been compressed using GZip or BZip2. So for example if you have configured the logrotate to compress the log files then those compressed log files can be directly opened up, without the need to use Ark/bzip2/gzip to decompress them.

Just open KWrite, navigate to File > Open.
In the location/path enter the directory where the compressed log file is located
Select the compressed file and click on open

Caveats

• This will not work with log files or text files that have been compressed with zip or rar or 7z file format
• If you have a archive file that has multiple files inside the archive then this will not work.

By accident I found that clonezilla will make a bootable image of your hibernating pc. The only real trick other than going from hibernation and booting directly into clonezilla is to make sure your backup location is at the root of the drive and whatever you do, let it finish. You can pull the flash drive out once you hear the horns with the 'ps' flag (playsound) option. Also, once you've made the backup and you reboot out of hibernation you will have to boot again to see the backup folder you made. Strange but true.

Old but new app. It comes with some preinstalled themes. My screenshot shows app with theme disabled.

+1, much improved overall, but the themes make the results pages almost unreadable so I too disabled the themes. The information under various sections is very nicely presented now and the benchmark tests make more sense overall. My Ryzen 5 5600G, which is slighted against the Ryzen 5 5600X got better results in all tests, so it must have a rather aged database to start with.

My addition to the list would have to be the Live Remaster tools for those who might want to update a fully featured Live USB made with our LUM without having to download a snapshot and creating another, though I do not recommend it be done with slow USB drives, always use a faster unit that can achieve a minimum sustained 65+ MBPS write speed, or a USB-SSD.

Combine the above with the MX Live USB Maker and after mounting an updated L-USB, you can make a clone of it as a secondary backup, and use a different sized flash drive. In the attached image, I am cloning a 128GB USB-SSD to a 256GB Ultra-fast regular USB Flash drive that will hold a sustained write speed of 120MBPS.
Note: in steps 8, 9 & 10, I am allocating 10% of the drive space (~25GB) for the Live USB and the remaining space for cross-platform storage.

The horizontal calendar looks awesome. Need this on my desktop too. A few questions though.

• In the conky script the value of maximum_width = 1280 is given. I am assuming that this is for screens with resolution of 1280X780 and not for screens with resolution of 1920X1280. Is that correct?
• In the conky script the value of update_interval is 0.5. Considering that this needs to be updated only once every day, can it be changed to a higher value?

This is a great conky script. Will defintely incorporate it. Thanks @siamhie .

[*] In the conky script the value of maximum_width = 1280 is given. I am assuming that this is for screens with resolution of 1280X780 and not for screens with resolution of 1920X1280. Is that correct?

Maximum width of window in pixels for the conky. http://ifxgroup.net/conky.htm#maximum_width

I've turned on borders to give you an idea of where everything lines up.

[*] In the conky script the value of update_interval is 0.5. Considering that this needs to be updated only once every day, can it be changed to a higher value?

Update interval in seconds. Fractions of a second are allowed using a decimal point. http://ifxgroup.net/conky.htm#update_interval

This one you can remove as there is nothing being updated for 24 hours.
