I would like to multiply the attribute in viewBox of svg-files by a factor of ten.

I want to change
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100" version="1.1"> to <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1000 1000" version="1.1"><g transform="scale(10)">
(I need it for a workaround of a librsvg-bug)

My current script looks like this:

#!/bin/bash

#defining file
export i=test.svg

#Define file as a variable
export h=$(sed -r 's/<svg ([-[:alnum:]=" ./:,]+) viewBox="([-[:digit:]]+) ([-[:digit:]]+) ([[:digit:]]+).([[:digit:]])([[:digit:]]*) ([[:digit:]]+).([[:digit:]])([[:digit:]]*)"([-[:alnum:]=" ./:,]+)>/<svg 1 viewBox="0 0 23.40 56.70"8><g transform="scale(10)">/' $i)

#Reading out the relevant line
export j=$(ls -l|grep -E "viewBox="[-[:digit:].]1,5 [-[:digit:].]1,5 [[:digit:].]3,7 [[:digit:].]3,7" $i)

#Insert a special character to define the point of splitting
export l=$(echo $j | sed -e "s/viewBox="/>/g" )

#split at this special character and take the part afterwards
export m=$(echo $l | cut -f2 -d">")

#Multiply the four numbers by a factor of 10
export n=$(echo $m | awk 'printf "%f %f %f %fn",$1*10,$2*10,$3*10,$4*10')

#Replace the old four numbers with the new four numbers
sed -ri "s/<svg([-[:alnum:]=" ./:;,#]*) viewBox="[-[:digit:].]+ [-[:digit:].]+ [[:digit:].]+ [[:digit:].]+"([-[:alnum:]=" ./:,]+)>/<svg 1 viewBox="$n"2><g transform="scale(10)">/" $i

This is neither beautiful, nor always working. (for example it won't work if there is an inline svg in an mother-svg embedded (example))

You can use whatever you want it should:

• Work on Ubuntu aswell on Cygwin


• should be a batchcommand
