Commands using xargs (769)
-
Creates a command alias ('cr' in the above example) that searches the contents of files matching a set of file extensions (C & C++ source-code in the above example) recursively within the current directory. Search configured to be in colour, ignore-case, show line numbers and show 4 lines of context. Put in shell initialisation file of your choice. Trivially easy to use, e.g:
cr sha1_initShow Sample Output0alias cr='find . 2>/dev/null -regex '\''.*\.\(c\|cpp\|pc\|h\|hpp\|cc\)$'\'' | xargs grep --color=always -ni -C2' -
0find ~ -name '*.mp4' | xargs mplayer
-
0find . -name Root -print | xargs rm -f

convenience.
0svn st | grep ^\? | awk '{print $2}' | xargs svn add -
0find . -type d -execdir du -sh '{}' ';' | grep -E "[0-9]+K" | sed 's/^[0-9\.]\+K[\t ]\+//' | tr "\n" "\0" | xargs -0 rm -rf
-
0find start_dir -name *.txt | xargs -J % cp % end_dir/

0svn st | grep ^? | xargs svn add 2> /dev/null

These part of the command: svn status | grep '^\?' => find new file or directory on working copy sed -e 's/^\?//g' => remove "^" character on the first character of file name xargs svn add => add file to subversion repository You can modify above command to other circumtances, like revert addition files or commit files that have been modified. ^_^
0svn status | grep '^\?' | sed -e 's/^\?//g' | xargs svn add -
Find all corrupted jpeg in the current directory, find a file with the same name in a source directory hierarchy and copy it over the corrupted jpeg file. Convenient to run on a large bunch of jpeg files copied from an unsure medium. Needs the jpeginfo tool, found in the jpeginfo package (on debian at least).
0for i in *jpg; do jpeginfo -c $i | grep -E "WARNING|ERROR" | cut -d " " -f 1 | xargs -I '{}' find /mnt/sourcerep -name {} -type f -print0 | xargs -0 -I '{}' cp -f {} ./ ; done -
automatically add and remove files in subversion so that you don't have to do it through the annoying svn commands anymore
0svn st | grep '^\?' | awk '{print $2}' | xargs svn add; svn st | grep '^\!' | awk '{print $2}' | xargs svn rm -
0find . -name '*.m4a' | xargs -I audiofile mplayer -ao pcm "audiofile" -ao pcm:file="audiofile.wav"

0/originalInstall/gem list | tr -d '(),' | xargs -L 1 sudo ./gemInst.sh -
This is better than doing a "for `find ...`; do ...; done", if any of the returned filenames have a space in them, it gets mangled. This should be able to handle any files. Of course, this only works if you have rename installed on your system, so it's not a very portable command.
0find -name '*oldname*' -print0 | xargs -0 rename 's/oldname/newname/' -
0ls -t1 | head -n1 | xargs tail -f
-
If you want certain files out of a directory hierarchy, this will copy just the listed files, but will create the directory hierarchy in the new location ($DIR/)
0cat files.txt | xargs tar -cv | tar -x -c $DIR/ -
This will drop you into vim to edit all files that contain your grep string.
0grep -ir 'foo' * | awk '{print $1}' | sed -e 's/://' | xargs vim -
saves one command. Needs GNU grep though :-(
0grep -ir 'foo' * | awk -F '{print $1}' | xargs vim -
This is really fast :)

List all text files in the current directory.

0find . -name "*.txt" | xargs sed -i "s/old/new/"
-
Searches for all .project files in current folder and below and uses "svn info" to get the last changed revision. The last sed joins every two lines. Show Sample Output
0find . -iname ".project"| xargs -I {} dirname {} | LC_ALL=C xargs -I {} svn info {} | grep "Last Changed Rev\|Path" | sed "s/Last Changed Rev: /;/" | sed "s/Path: //" | sed '$!N;s/\n//' - ‹ First < 12 13 14 15 16 > Last ›
