Find all books on my systems and move them into folder. The -0 switches are to handle spaces etc. in the filenames. Why would you need this? Locate uses an index, so it's super quick, and xargs is more elegant than a for loop.

Removes directories which are less than 1028KB total. This works for systems where blank directories are 4KB. If a directory contains 1 MB (1024KB) or less, it will remove the directory using a path relative to the directory where the command was initially executed (safer than some other options I found). Adjust the 1028 value for your needs. It would be helpful to test the results before proceeding with the removal. Simply run all but the last two commands to see a list of what will be removed: du | awk '{if($1<1028)print;}' | cut -d $'\t' -f 2- If you're unsure what size a blank folder is, test it like this: mkdir test; du test; rmdir test

Works for Debian an sons distros. With a bad internet connection sometime I download the updateable packages in another place, but I can't be there all time takes upgrade every packages... so I execute this for update only packages that are in Debian's apt cache.

Just added a little url encoding with sed - urls with spaces don't work well - this also works against instead of enclosure and adds a sample to show that you can filter against links at a certain domain Show Sample Output

Converts all the png files in a directory to a bunch of gifs - changing only the file extension. Converts them in parallel - simply change the '4' to match the number of CPUs you have, or the number you want to dedicate to the conversion process.

Compare the content of the files in the current directory with files of the same name in the duplicate directory. Pop Quiz: You have a duplicate of a directory with files of the same name that might differ. What do you do? You could use diff to compare the directories, but that's boring and it isn't as clever as find -print0 with xargs. Note: You must omit stderr redirect 2>/dev/null to see the list of missing files from DUPDIR, if any. Hint: Redirect stderr to a new file to produce a more readable list of files that are missing from DUPDIR. Warning: This doesn't tell you if DUPDIR contains files not found in the current directory so don't delete DUPDIR. Show Sample Output

xargs deals badly with special characters (such as space, ' and "). To see the problem try this: touch important_file touch 'not important_file' ls not* | xargs rm Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem.

You WILL have problems if the files have the same name. Use cases: consolidate music library and unify photos (especially if your camera separates images by dates). After running the command and verifying if there was no name issues, you can use ls -d */ | sed -e 's/^/\"/g' -e 's/$/\"/g' | xargs rm -r to remove now empty subdirectories.
