Linux – make rsync output only the summary

backuplinuxrsync

I use rsync to backup a directory which is very big, containing many sub-directories and files, so I don't want to see the "incremental file list". I just want to know the summary in the end. If I use the argument -q, nothing is output at all. Can I make rsync output only the summary?

Use the following:

rsync -vr src/ dest/ | sed '0,/^$/d'

Explanation: rsync is run in verbose mode using the -v flag. It outputs a detailed file list, an empty line and the summary. Now sed is used to take advantage of the fact that the summary is separated by an empty line. Everything up to the first empty line is not printed to stdout. ^$ matches an empty line and d prevents it from being output.

Linux – Copying a large directory tree locally? cp or rsync

I would use rsync as it means that if it is interrupted for any reason, then you can restart it easily with very little cost. And being rsync, it can even restart part way through a large file. As others mention, it can exclude files easily. The simplest way to preserve most things is to use the -a flag – ‘archive.’ So:

rsync -a source dest

Although UID/GID and symlinks are preserved by -a (see -lpgo), your question implies you might want a full copy of the filesystem information; and -a doesn't include hard-links, extended attributes, or ACLs (on Linux) or the above nor resource forks (on OS X.) Thus, for a robust copy of a filesystem, you'll need to include those flags:

rsync -aHAX source dest # Linux
rsync -aHE source dest  # OS X

The default cp will start again, though the -u flag will "copy only when the SOURCE file is newer than the destination file or when the destination file is missing". And the -a (archive) flag will be recursive, not recopy files if you have to restart and preserve permissions. So:

cp -au source dest

Linux Bash – How to Sort du -h Output by Size

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)
