find . -empty -type d -print0 | xargs -0 rmdir -p

It starts in the current working directory.

It removes the empty directory and its ancestors (unless the ancestor contains other elements than the empty directory itself).

It will print a failure message for every directory that isn't empty.

This command handles correctly directory names containing single or double quotes, spaces or newlines.

If you do not want only to remove all the ancestors, just use:

find . -empty -type d -print0 | xargs -0 rmdir
rmdir --ignore-fail-on-non-empty -p **/*(/^F)
2012-09-18 20:28:46
User: xro
Functions: rmdir

recursively delete empty directories and directories which only contain empty directories using zsh globbing syntax. ** is for recursive globbing. *(/^F) matches all entries that are directories which are not full.

If you only want to delete empty directories and not those directories which contained only empty directories and will be empty afterwards, just leave out the options to rmdir:

rmdir **/*(/^F)

Bash snippet to force GNU/Linux keyboard settings, layout and configuration.

Usefull when some GNU/Linux distributions such as *Ubuntu's store only limited configation options due to demonstration purposes on LiveUSB or Live persistent devices.

Overcomes the English QWERTY to French AZERTY settings failure.

This shows every bit of information that stat can get for any file, dir, fifo, etc. It's great because it also shows the format and explains it for each format option.

If you just want stat help, create this handy alias 'stath' to display all format options with explanations.

alias stath="stat --h|sed '/Th/,/NO/!d;/%/!d'"

To display on 2 lines:

( F=/etc/screenrc N=c IFS=$'\n'; for L in $(sed 's/%Z./%Z\n/'<<<`stat --h|sed -n '/^ *%/s/^ *%\(.\).*$/\1:%\1/p'`); do G=$(echo "stat -$N '$L' \"$F\""); eval $G; N=fc;done; )

For a similarly powerful stat-like function optimized for pretty output (and can sort by any field), check out the "lll" function

From my .bash_profile ->

find $PWD -maxdepth 1 -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n'

I love this function because it tells me everything I want to know about files, more than stat, more than ls. It's very useful and infinitely expandable.

find $PWD -maxdepth 1 -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n' | sort -rgbS 50%

00761 drwxrw---x askapache:askapache 777:666 [06/10/10 | 06/10/10 | 06/10/10] [d] /web/cg/tmp

The key is:

# -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n'

which believe it or not took me hundreds of tweaking before I was happy with the output.

You can easily use this within a function to do whatever you want.. This simple function works recursively if you call it with -r as an argument, and sorts by file permissions.

lsl(){ O="-maxdepth 1";sed -n '/-r/!Q1'<<<$@ &&O=;find $PWD $O -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n'|sort -rgbS 50%; }

Personally I'm using this function because:

lll () { local a KS="1 -r -g"; sed -n '/-sort=/!Q1' <<< $@ && KS=`sed 's/.*-sort=\(.*\)/\1/g'<<<$@`; find $PWD -maxdepth 1 -printf '%.5m %10M %#9u:%-9g %#5U:%-5G [%AD | %TD | %CD] [%Y] %p\n'|sort -k$KS -bS 50%; }

# i can sort by user

lll -sort=3

# or sort by group reversed

lll -sort=4 -r

# and sort by modification time

lll -sort=6

If anyone wants to help me make this function handle multiple dirs/files like ls, go for it and I would appreciate it.. Something very minimal would be awesome.. maybe like:

for a; do lll $a; done

Note this uses the latest version of GNU find built from source, easy to build from gnu ftp tarball. Taken from my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html

Remove all empty directories below the current directory. If directories become empty as the results of this, remove those too.

A little bit smaller, faster and should handle files with special characters in the name.

Get your colorized grep output in less(1). This involves two things: forcing grep to output colors even though it's not going to a terminal and telling less to handle those properly.

find -type f -printf '%P\000' | egrep -iz '\.(avi|mpg|mov|flv|wmv|asf|mpeg|m4v|divx|mp4|mkv)$' | sort -z | xargs -0 ls -1
