Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

List directories recursively showing its sizes using only ls and grep

ls -lhR

Lists everithing using -l "long listing format" wich includes the space used by the folder. Displays it in -h "human readable form" (i.e. 2.2G, 32K), and -R recurses subfolders.

grep -e using a regex, show lines containing the word "total" or a ":" at the end of the line (those with the name of the folder) only.


There are 2 alternatives - vote for the best!

What is wrong with

du -h


Comment by michelsberg 114 weeks and 1 day ago

I don't have permission to run du (or to install it) on the server.

Comment by Sebasg 114 weeks ago

Ok, I thought du would exist on any relevant *nix since it is in the coreutils.

To memorize it better, german speakers can use

ls -Roh | grep "insgesamt\|:$"

("Roh" means raw)

ls -o is almost identical to ls -l, but does only list owner info (and no group name).
