Answer 1

You can do it with the following command:

find /path/to/dir-with-big-file/ -type f -printf "%s\t%p\n" | sort -n -r | head -n 1 | awk '{print $2}' | xargs -I % sh -c 'ln -sf % /path/to/symlink'

which breaks down as follows:

• find /path/to/dir-with-big-file/ -type f -printf "%s\t%p\n" - find files and print %s files size and %p name.
• sort -n -r | head -n 1 sort -n -r | head -n 1 - sort in reverse order and get the first (ie biggest) one
• awk '{print $2}' | xargs -I % sh -c 'ln -sf % /path/to/symlink' awk '{print $2}' | xargs -I % sh -c 'ln -sf % /path/to/symlink' - extract full file name and create or update a symlink (eg in you case long_file)
