From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

maybe something like this using mediainfo and exiftool?

#!/bin/bash

for file in *.jpg *.mp4; do
    # Extract date and time from file's metadata
    if [[ $file == *.jpg ]]; then
        datetime=$(exiftool -DateTimeOriginal -d "%Y%m%d_%H%M%S" "$file" | awk -F': ' '{print $2}')
    else
        datetime=$(mediainfo --Output="General;%File_Modified_Date%" "$file" | awk -F' ' '{print $1"_"$2}' | tr -d ':' | tr -d '-')
    fi

    # If datetime was found, rename the file 
    if [ -n "$datetime" ]; then
        # Extract extension of file 
        ext="${file##*.}"
        # Rename file with date and time as prefix (remove echo after testing it)
        echo mv -- "$file" "${datetime}.${ext}"
    fi

done
