The files are automatically uncompressed when they reach the destination machine. This is a fast way to backup your server to your local computer while it's running (shutting down services is recommended).

A file named "exclude.txt" is needed at /tmp/ containing the following :

/dev/*

/media/*

/mnt/*

/proc/*

/sys/*

/tmp/*

/home/*/.local/share/Trash

/home/*/.gvfs

/home/*/.cache

/home/*/.thumbnails

/etc/fstab

/lib/modules/*/volatile/.mounted

/var/run/*

/var/lock/*

/var/tmp/*

/var/cache/apt/archives/*

/lost+found/*

Useful when you want to cron a daily deletion task in order to keep files not older than one year. The command excludes .snapshot directory to prevent backup deletion.

One can append -delete to this command to delete the files :

find /path/to/directory -not \( -name .snapshot -prune \) -type f -mtime +365 -delete
rsync -ayz -e ssh --exclude=/proc --exclude=/sys --exclude=/dev / root@NEWHOST:/MNTDIR

Copies the complete root-dir of a linux server to another one, where the new harddisks formated and mountet. Very useful to migrate a root-server to another one.

rsync -rv --exclude .svn src/dir/ dest/dir/
rm -R `ls | egrep -v 'dir1|dir2|file1'`
find . -type f ! -name "*.foo" -name "*.bar" -delete

This command is recursive and will delete in all directories in ".". It will find and delete all files not specified with ! -name "pattern". In this case it's file extensions. -type f means it will only find files and not directories. Finally the -delete flag ask find to delete what it matches. You can test the command by running it first without delete and it will list the files it will delete when you run it.

git diff --numstat -w --no-abbrev | perl -a -ne '$F[0] != 0 && $F[1] !=0 && print $F[2] . "\n";'

Only shows files with actual changes to text (excluding whitespace). Useful if you've messed up permissions or transferred in files from windows or something like that, so that you can get a list of changed files, and clean up the rest.

rsyncs files to a server excluding listed files

also a file can be used to exclude common exclude rules and/or to exclude a ton of files, like so:

rsync --exclude-from '~/.scripts/exclude.txt'

where exclude.txt has one rule per line:

*.mp3

*.svn*
