  • FInd the 10 biggest files taking up disk space

    This combines the above two command into one. Note that you can leave off the last two commands and simply run the command as "find /home/ -type f -exec du {} \; 2>/dev/null | sort -n | tail -n 10" The last two commands above just convert the output into human readable format.


    1
    find /home/ -type f -exec du {} \; 2>/dev/null | sort -n | tail -n 10 | xargs -n 1 du -h 2>/dev/null

  • simple du command to give size of next level of subfolder in MB

    If you're only using -m or -k, you will need to remember they are either in Megabyte or kilobyte forms. So by using -B, it gives you the unit of the size measurement, which helps you from reading the result faster. You can try with -B K as well. Show Sample Output

Find and display most recent files using find and perl
This pipeline will find, sort and display all files based on mtime. This could be done with find | xargs, but the find | xargs pipeline will not produce correct results if the results of find are greater than xargs command line buffer. If the xargs buffer fills, xargs processes the find results in more than one batch which is not compatible with sorting. Note the "-print0" on find and "-0" switch for perl. This is the equivalent of using xargs. Don't you love perl? Note that this pipeline can be easily modified to any data produced by perl's stat operator. eg, you could sort on size, hard links, creation time, etc. Look at stat and just change the '9' to what you want. Changing the '9' to a '7' for example will sort by file size. A '3' sorts by number of links.... Use head and tail at the end of the pipeline to get oldest files or most recent. Use awk or perl -wnla for further processing. Since there is a tab between the two fields, it is very easy to process.
