Prints per-line contribution per author for a GIT repository

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

Sometimes jittery data hides trends, performing a rolling average can give a clearer view.

Prints per-line contribution per author for a GIT repository

You'll run into trouble if you have files w/ missing newlines at the end. I tried to use PAGER='sed \$q' git blame and even PAGER='sed \$q' git -p blame to force a newline at the end, but as soon as the output is redirected, git seems to ignore the pager.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Random unsigned integer

works at least in bash. returns integer in range 0-32767. range is not as good, but for lots of cases it's good enough.

Benchmark SQL Query

Benchmark a SQL query against MySQL Server. The example runs the query 10 times, and you get the average runtime in the output. To ensure that the query does not get cached, use `RESET QUERY CACHE;` on top in the query file.

Replace all backward slashes with forward slashes

Use -i to edit file directly: sed -i 's|\\|\/|g' file

Forwards connections to your port 2000 to the port 22 of a remote host via ssh tunnel

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Dump and bz2compress a mysql db

To also move the db backup to another location you could pass the output to the dd command instead of a file $mysqldump -u user -h host -ppwd -B dbname | bzip2 -zc9 | dd ssh usr@server "dd of=db_dump"
