Ubuntu – Is is possible to export Inkscape files for inDesign

This might not be the kind of answer you are looking for, but one thing you can do to make Inkscape feel faster is to change the display mode from "Normal" to "No Filters". Obviously you don't see the filters in that mode, but the preview renders a lot faster.

The option is in the menu View > Display mode > No Filters

Inspired by the previously accepted answer I came up with this one-liner:

For Inkscape version 0.92.4 and earlier:

for file in *.svg; do inkscape $file -e ${file%svg}png; done

This way you don't need to call a script. If you wanted to, you could create an alias for converting all svgs in the current directory to pngs:

alias svgtopng='for file in *.svg; do inkscape $file -e ${file%svg}png; done'

For Inkscape version 1.0 Beta and later:

for file in *.svg; do inkscape $file -o ${file%svg}png; done

This way you don't need to call a script. If you wanted to, you could create an alias for converting all svgs in the current directory to pngs:

alias svgtopng='for file in *.svg; do inkscape $file -o ${file%svg}png; done'
