Figures out total line contribution per author for an entire GIT repo. Includes binary files, which kind of mess up the true count. If crashes or takes too long, mess with the ls-file option at the start: git ls-files -x "*pdf" -x "*psd" -x "*tif" to remove really random binary files git ls-files "*.py" "*.html" "*.css" to only include specific file types Based off my original SVN version: http://www.commandlinefu.com/commands/view/2787/prints-total-line-count-contribution-per-user-for-an-svn-repository Show Sample Output
4git ls-files | xargs -n1 -d'\n' -i git-blame {} | perl -n -e '/\s\((.*?)\s[0-9]{4}/ && print "$1\n"' | sort -f | uniq -c -w3 | sort -r -
Sometimes jittery data hides trends, performing a rolling average can give a clearer view.
3awk 'BEGIN{size=5} {mod=NR%size; if(NR<=size){count++}else{sum-=array[mod]};sum+=$1;array[mod]=$1;print sum/count}' file.dat -
Shows how many Windows and Linux devices are on your network. May add support for others, but that's all that are on my network right now. Show Sample Output

You'll run into trouble if you have files w/ missing newlines at the end. I tried to use
PAGER='sed \$q' git blameand evenPAGER='sed \$q' git -p blameto force a newline at the end, but as soon as the output is redirected, git seems to ignore the pager.-1git ls-files | while read i; do git blame $i | sed -e 's/^[^(]*(//' -e 's/^\([^[:digit:]]*\)[[:space:]]\+[[:digit:]].*/\1/'; done | sort | uniq -ic | sort -nr -
check apache2 status with a lot of details
