The thunderbird message datastores get corrupt some times causing random failures, compaction to fail and general suck in thunderbird. Removing them causes thunderbird to rebuild the indexes and makes things quick again.

Take a folder full of files and split it into smaller folders containing a maximum number of files. In this case, 100 files per directory. find creates the list of files xargs breaks up the list into groups of 100 for each group, create a directory and copy in the files Note: This command won't work if there is whitespace in the filenames (but then again, neither do the alternative commands :-)
-1files -type f | xargs -n100 | while read l; do mkdir $((++f)); cp $l $f; done -
One of my friends committed his code in the encoding of GB2312, which broke the build job. I have to find his code and convert.

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.
-2tar -tf <file.tar.gz> | parallel rm -
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.
-2svn status |grep '\?' |awk '{print $2}'| parallel -Xj1 svn add -
xargs deals badly with special characters (such as space, ' and "). In this case if you have a file called '12" record'. Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem. Both solutions work bad if the number of files is more than the allowed line length of the shell.
-2svn st | cut -c 9- | parallel -X tar -czvf ../backup.tgz -
If a directory name contains space xargs will do the wrong thing. Parallel https://savannah.nongnu.org/projects/parallel/ deals better with that. Show Sample Output
-2du -s * | sort -nr | head | cut -f2 | parallel -k du -sh -
-2ls . | xargs file | grep text | sed "s/\(.*\):.*/\1/" | xargs gedit
-
-2find . -name "*noticia*" -name "*jhtm*" -name "*.tpl" -exec grep -li "id=\"col-direita\"" '{}' \; | xargs -n1 mate

This will, for an application that has already been removed but had its configuration left behind, purge that configuration from the system. To test it out first, you can remove the last -y, and it will show you what it will purge without actually doing it. I mean it never hurts to check first, "just in case." ;)
-3dpkg-query -l| grep -v "ii " | grep "rc " | awk '{print $2" "}' | tr -d "\n" | xargs aptitude purge -y -
This deals nicely with files having special characters in the file name (space ' or "). Parallel is from https://savannah.nongnu.org/projects/parallel/
