Yesterday we tested the BCI-controlled wheelchair outside of our lab. Ganga took a couple of cool pictures.

Easy tag creator

Published on August 10, 2010 in Code and Misc. 0 Comments

I often need to distribute some code to people that do not have access to my SVN/GIT repositories. Furthermore, I create daily tags automatically with cron. Here you have the bash script I normally use.

Please check the example below to understand how it works. Since I run this script for a large number of projects, I fork a tar process for each directory provided as argument. Remove the ampersand (&) at the end of line 22 to disable forking. Lines 28 to 42 wait for all the forked processed before exiting.

Last but not least, if the directories provided as argument contain a .git/ or .svn/ subdirectory, the archive name changes accordingly.

if [ z"$1" == "z" ]; then
	echo "Error: ctk_tag DIRECTORY..."
	exit;
fi
 
PIDS=""
for x in $@; do
	BASENAME=`basename $x`
	TIMESTAMP=`date +%Y%m%d`
	if [ -e $1/.svn ]; then
		REPO="svn"
	elif [ -e $1/.git ]; then
		REPO="git"
	else
		REPO=""
	fi
	ARCHIVE=${BASENAME}_${REPO}${TIMESTAMP}.tar.bz2 
 
	tar cjf $ARCHIVE $x &
	PID=$!
	echo "[ctk_tag] PID=$PID $x--&gt;$ARCHIVE"
	PIDS="$PID $PIDS"
done
 
while true; do
	TPIDS=""
	for x in $PIDS; do
		PIDCHECK=`ps ax | grep $x | grep -v grep`
		if [ -n "$PIDCHECK" ]; then
			TPIDS="$x $TPIDS"
		fi
	done
 
	if [ "z$TPIDS" == "z" ]; then
		exit 0;
	fi

Before/After

Is it better now or before? Well, we were very happy to trash the TV thing, replacing it with the cheapest IKEA couch. So it is better now. I cannot say the same for my head after a routine recording with Ganga(dhar Garipelli). Btw, the holes in my head are nobody’s fault, I just wonder about the word “non-invasive”.
