Finding files is a very common practice for all operating systems. I don’t think this is a trick. but it’ll be very helpful for newbies to know the exact command to find big files, especially when you don’t have enough space on your machine and want to know which files take most of your space.
find / -size +10240000c -exec du -h {} ;
This command will list all the files that are larger than 10 Mb, specifying the exact size they have. du output is used to calculate file sizes and / is the directory where we are looking for files.
