First to test how the renaming will look like you can use the command with -n switch as:
rename -n 's/\.([^.]+)$/.\L$1/' *
If you are satisfied just remove “-n” and all files will have it’s extensions renamed to lowercase.
rename 's/\.([^.]+)$/.\L$1/' *
To renew all your due certificates manually you can use:
certbot renew
To remove one domain from the list of certificates you can use:
certbot delete
You will be presented with a list from which you can choose which domain should be removed from configuraiton.
If you are trying to install Linux on HP EliteBook 745G2 and your WiFi is not working you could try to edit /etc/default/grub file and add intremap=off after quiet splash like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intremap=off"
Reboot and your WiFi should be working between reboots.
You can do this for any app from PortableApps.com for example if you want to pass command line argument to GoogleChromePortable, go to [X]:\PortableApps\GoogleChromePortable to folder Other\Source and copy the file GoogleChromePortable.ini to your
[X]:\PortableApps\GoogleChromePortable folder.
Where [X] represents your drive letter where PortableApps directory is found.
Open the file in text editor and find:
AdditionalParameters=""
and change it to any value you want to pass to main app, for example proxy definition:
AdditionalParameters="--proxy-server=127.0.0.1:3128"
Save the file and run the portable application again.
