script to show all files with disk usage sizes

Normally to get the disk usage of a folder you use get properties on the rightclick or similar. However there are hidden files starting with . in their name that you can get info on, only in the terminal, using the du -sh command. If you have hundreds of them (which you do!) this becomes tedious. The following script gives you a directory listing with the files all indicated in file sizes and highlights on files of megabytes or gigabytes in size. 

#!/bin/bash


# Set Internal Field Separator to handle spaces in filenames

IFS=$'\n'


# Loop through all files and directories

for i in $(/bin/ls -A); do 

    size=$(du -sh "$i" | awk '{print $1}')

    

    # Apply colors: bold for MB, bright bold for GB

    case "$size" in

        *M) color="\e[1m" ;;       # Bold for Megabytes

        *G) color="\e[1;97m" ;;    # Bright bold (white) for Gigabytes

        *) color="" ;;             # Default for others

    esac


    # Print formatted output with coloring

    printf "%-50s %b%10s\e[0m\n" "$i" "$color" "$size"

done | less -R

Enable Anydesk on Linux

 By default, Anydesk doesn't work on Ubuntu as it uses a different display server than what is expected by Anydesk (it expects the traditional X11 rather than Wayland). Dump this into a file, say, "fix_anydesk.sh", and then run it with sudo bash fix_anydesk.sh The script: #!/bin/bash # Check if the user has root privileges if [[ $EUID -ne 0 ]]; then    echo "This script must be run as root"     exit 1 fi # Backup the GDM configuration file GDM_CONFIG="/etc/gdm3/custom.conf" if [[ -f "$GDM_CONFIG" ]]; then     cp "$GDM_CONFIG" "$GDM_CONFIG.bak"     echo "Backup of custom.conf created." else     echo "GDM configuration file not found."     exit 1 fi # Disable Wayland by uncommenting and setting the 'WaylandEnable' option to false sed -i 's/#WaylandEnable=false/WaylandEnable=false/' "$GDM_CONFIG" # Inform the user echo "Wayland has been disabled. The system will use X11 inste...

Pause a program which is using too much CPU

Sometimes your battery is running low and you need to pause a program without quitting it or force-quitting it, so that you can preserve battery but not lose the job that the program is doing. To do this,  Step 1. open a terminal Step 2. type:  ps ax | grep -i  "<program name>" so for example, if it's photoshop you need to pause, replace "<program name>" with "photoshop" Step 3. Next to the results on the far left you'll see a number, usually with 5 digits. E.g. 12345. Step 4. Type:  kill -STOP 12345 where 12345 are the numbers obtained in Step 2-3. Step 5. When you want to resume the program, type kill -CONT 12345 It should then continue to operate or run as usual without problems.
