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.

Commands tagged xargs from sorted by
Terminal - Commands tagged xargs - 124 results
curl $1 | grep -E "http.*\.mp3" | sed "s/.*\(http.*\.mp3\).*/\1/" | xargs wget
2015-09-17 13:19:53
User: theodric
Functions: grep sed xargs

The difference between the original version provided and this one is that this one works rather than outputting a wget error

locate -0 -i *barthes* | xargs -0 mv -t ~/'Library/Books/Barthes, Roland'
2014-11-16 18:26:35
User: qdrizh
Functions: locate mv xargs
Tags: mv xargs locate

Find all books on my systems and move them into folder. The -0 switches are to handle spaces etc. in the filenames.

Why would you need this? Locate uses an index, so it's super quick, and xargs is more elegant than a for loop.

gcloud components list | grep "^| Not" | sed "s/|\(.*\)|\(.*\)|\(.*\)|/\2/" | xargs echo gcloud components update
2014-10-13 20:52:25
User: wires
Functions: echo grep sed xargs

Google Cloud SDK comes with a package manager `gcloud components` but it needs a bit of `sed` to work. Modify the "^| Not" bit to change the package selection. (The gcloud --format option is currently broken)

find . -name "*.pdf" -print0 | xargs -r0 stat -c %y\ %n | sort|awk '{print $4}'|gawk 'BEGIN{ a=1 }{ printf "mv %s %04d.pdf\n", $0, a++ }' | bash
2014-09-23 06:40:45
Functions: awk find gawk printf stat xargs
Tags: sort awk find xargs

Caution: distructive overwrite of filenames

Useful for concatenating pdfs in date order using pdftk

echo {-1..-5}days | xargs -n1 date +"%Y-%m-%d" -d
parallel convert {} {.}.png ::: *.svg
2014-04-12 06:39:02

Use GNU Parallel: short, easy to read, and will run one job per core.

find . -name \*.svg -print0 | xargs -0 -n1 -P4 -I{} bash -c 'X={}; convert "$X" "${X%.svg}.png"'
2014-04-11 14:30:30
User: flatcap
Functions: bash find xargs

Convert some SVG files into PNG using ImageMagick's convert command.

Run the conversions in parallel to save time.

This is safer than robinro's forkbomb approach :-)

xargs runs four processes at a time -P4

gsettings get org.gnome.desktop.background picture-uri | xargs nautilus
ls -1 | xargs ruby -e'puts ARGV.shuffle'
for i in */; do echo $(find $i -type f -regextype posix-extended -regex ".*\.(mp3|ogg|wav|flac)" | wc -l) $i ; done
find . -type d -maxdepth 1 -print0 | xargs -0 -I{} sh -c 'find "{}" -type f | grep "ogg\|mp3\|wav\|flac$" | wc -l | tr -d "\n"; echo " {}"'
2013-12-22 13:40:29
User: dbrgn
Functions: echo find grep sh tr wc xargs

This lists the number of ogg/mp3/wav/flac files in each subdirectory of the current directory. The output can be sorted by piping it into "sort -n".

find . -name '*pdf*' -print0 | xargs -0 ls -lt | head -20
2013-10-03 21:58:51
User: fuats
Functions: find head ls xargs

Sorts by latest modified files by looking to current directory and all subdirectories

wget -q -O- http://example-podcast-feed.com/rss | grep -o "<enclosure[ -~][^>]*" | grep -o "http://[ -~][^\"]*" | xargs wget -c
2013-09-24 12:38:08
User: talha131
Functions: grep wget xargs

This script can be used to download enclosed files from a RSS feed. For example, it can be used to download mp3 files from a podcasts RSS feed.

pbpaste | xargs wget
2013-08-11 23:12:10
User: loopkid
Functions: xargs

On Linux substitute pbpaste with `xsel --clipboard --output` or `xclip -selection clipboard -o` (untested)

curl -s $1 | grep -o -i '<a href="//images.4chan.org/[^>]*>' | sed -r 's%.*"//([^"]*)".*%\1%' | xargs wget
2013-07-22 10:33:55
User: bugmenot
Functions: grep xargs

first grep all href images then sed the url part then wget

find ./ -type f -print0 | xargs -0 md5sum
ssh user@remotehost "find basedir -type d" | xargs -I {} -t mkdir -p {}
2013-07-17 07:14:32
User: neomefistox
Functions: mkdir ssh xargs

The directories are created in the local host with the same structure below of a remote base directory, including the 'basedir' in case that it does not exists.

You must replace user and remotehost (or IP address) with your proper values

ssh will ask for the password of the user in remotehost, unless you had included properly your hostname in the remote .ssh/known_hosts file.

find . -empty -type d -print0 | xargs -0 rmdir -p
2013-07-01 02:44:57
User: rafar
Functions: find rmdir xargs

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
watch 'ls -tr1 | tail -n1 | xargs tail'
2013-05-09 11:37:59
User: batandwa
Functions: tail watch xargs
Tags: tail ls xargs watch

Watches for file modifications in the current directory and tails the file.

ls *.jpg | xargs -n1 -i cp {} /external-hard-drive/directory
find /var/www/ -type f -print0 | xargs -0 chmod 644
find /var/www/ -type f -print0 | xargs -0 chmod 644
2013-03-28 11:10:30
User: FiloSottile
Functions: chmod find xargs
Tags: find xargs chmod

xargs is a more elegant approach to executing a command on find results then -exec as -exec is meant as a filtering flag.

find -type f | xargs ls -1tr
pwd|grep -o '/'|perl -ne '$x.="./.";print`readlink -f $x`'|xargs -tn1 chmod 755
2013-03-14 12:03:44
Functions: chmod grep perl pwd xargs

`pwd` returns the current path

`grep -o` prints each slash on new line

perl generates the paths sequence: './.', './../.', ...

`readlink` canonicalizes paths (it makes the things more transparent)

`xargs -tn1` applies chmod for each of them. Each command applied is getting printed to STDERR.
