#!/bin/sh

# "anonymize-svg" removes export paths and document names from all the SVG files
# in a directory, saving the original versions.

# The script should be in the same directory as the SVGs. It can be launched from
# the graphical user interface or called from the command line without argument.

# Detailed method:
# - make sure the first line (#!/bin/sh) wasn't lost during copy-pasting;
# - make the script executable (this can usually be done from the contextual
#   menu);
# - place it (or a softlink to it) in the directory containing the SVGs you
#   want to clean;
# - make sure none of the SVGs is open in Inskape;
# - open the SVG directory in the file browser (do not just unfold the parent
#   directory), then double-click on the script or launch it from the contextual
#   menu.

# A terminal will open and list the files which have been cleaned, and a
# subdirectory named saved-svg/ will be created to save the non-anonymized files.
# If the script is run twice in the same directory, backups of the non-anonymized
# files will be made in saved-svg/, but a third run will overwrite them.
