Functions: awk diff tar xargs

The result of this command is a tar with all files that have been modified/added since revision 1792 until HEAD. This command is super useful for incremental releases.

One of my friends committed his code in the encoding of GB2312, which broke the build job. I have to find his code and convert.

fdupes -r .

Tags: xargs parallel

If you have the fdupes command, you'll save a lot of typing. It can do recursive searches (-r,-R) and it allows you to interactively select which of the duplicate files found you wish to keep or delete.

files -type f | xargs -n100 | while read l; do mkdir $((++f)); cp $l $f; done
2011-02-15 23:15:16
User: flatcap
Functions: cp mkdir read xargs

Take a folder full of files and split it into smaller folders containing a maximum number of files. In this case, 100 files per directory.

find creates the list of files

xargs breaks up the list into groups of 100

for each group, create a directory and copy in the files

Note: This command won't work if there is whitespace in the filenames (but then again, neither do the alternative commands :-)

grep -l foo *cl*.log | xargs grep -lL bar

Uses xargs to call the second grep with the first grep's results as arguments

bargs { while read i; do "$@" "$i"; done }

recursively search dir for a a particular file type, search each file for a particular text.

Functions: find ln xargs
Tags: find xargs links

If you want to pull all of the files from a tree that has mixed files and directories containing files, this will link them all into a single directory. Beware of filesystem files-per-directory limits.

tail -f file |xargs -IX printf "$(date -u)\t%s\n" X
PROMPT_COMMAND='seq $COLUMNS | xargs -IX printf "%Xs\r" @'
find . -type f | while read line; do NEW_TS=`date -d@$((\`stat -c '%Y' $line\` + <seconds> )) '+%Y%m%d%H%M.%S'`; touch -t $NEW_TS ${line}; done

Functions: find read touch

Increase the modification date for the files selected with the find command.

cd /proc&&ps a -opid=|xargs -I+ sh -c '[[ $PPID -ne + ]]&&echo -e "\n[+]"&&tr -s "\000" " "<+/cmdline&&echo&&tr -s "\000\033" "\nE"<+/environ|sort'

Grabs the cmdline used to execute the process, and the environment that the process is being run under. This is much different than the 'env' command, which only lists the environment for the shell. This is very useful (to me at least) to debug various processes on my server. For example, this lets me see the environment that my apache, mysqld, bind, and other server processes have.

Here's a function I use:

aa_ps_all () { ( cd /proc && command ps -A -opid= | xargs -I'{}' sh -c 'test $PPID -ne {}&&test -r {}/cmdline&&echo -e "\n[{}]"&&tr -s "\000" " "<{}/cmdline&&echo&&tr -s "\000\033" "\nE"<{}/environ|sort&&cat {}/limits' ); }

This can be useful for transforming command-line args into input for xargs (one per line). This can also be done with ls if the args are filenames, but that's getting awfully close to Useless Use of Cat territory (http://partmaps.org/era/unix/award.html).

Similar to xargs -i, but works with builtin bash commands (rather than running "bash -c ..." through xargs)

Preserve file structure when coping and exclude some file o dir patterns

Convert all jpegs in the current directory into ~1024*768 pixels and ~ 150 KBytes jpegs

ls *.JPG | cut -d . -f 1 | xargs -L1 -i convert -resize 684 {}.JPG {}.jpg
grep -ZlRr -e BAD_SCRIPT_LINE * |xargs -0 sed -i 's/BAD_SCRIPT_LINE//g'

User: homoludens
Functions: grep sed xargs

recursive find and replace. important stuff are grep -Z and zargs -0 which add zero byte after file name so sed can work even with file names with spaces.
