Fast plot from bash.

Usually i need make tentative graphics of a data set, and this require use gnuplot, with command and others things, for this reason i make a little script for plot directly from the bash with arguments (file and options) using gnuplot (you need gnuplot installed in your system).

For example for plot a simple file with data (as here). a fast plot is made using :

xplot example.dat

For a more complex file as here, you can plot using :

xplot freefall.dat u 1:2 w lp

The script for plot from the bash its here :

#!/bin/sh
TMP="/tmp/gnuplot.tmp"
############################################################################
if [ $# != 0 ];
then
echo "set title \"Xplot Fast Plot with gnuplot\" ." > $TMP
echo "set xlabel \"x axes\"" >> $TMP
echo "set ylabel \"y axez\"" >> $TMP
echo -n "plot \"$1\" " >> $TMP
for i in $@
do
if [ $i != $1 ];then
echo -n "$i " >> $TMP
fi
done
echo "">>$TMP
gnuplot -persist $TMP
rm $TMP
else
echo "Please use xplot <file.dat> <options> to plot"
exit
fi


Now you can put this file in /usr/local/bin/ (with xplot or another name) and give execution permissions with :

chmod 755 /usr/local/bin xplot

Now, any user can run the xplot script.
