# we are free to compose the output filename written by the 2dir backend
# in whatever way we like... However, we must be careful when using the
# $jobtitle part -- the job may originate from a web browser and contain
# slashes and all kinds of illegal or problematic characters. Therefore
# we prefer to radically convert every "weird" character to an underscore
# for our current purpose...
sanitized_jobtitle="$(echo ${jobtitle} | tr [[:blank:]:/%\&=+?\\\\#\'\`\´\*] _)"
# the following lines would do (nearly) the same as the above, but slower
# -- yet better readable (and the above may be in need of some fixing still):
#sanitized_jobtitle="$(echo ${jobtitle} \
# |tr [:blank:] _ \
# |tr : _ \
# |tr \"\ \" _ \
# |tr / _ \
# |tr % _ \
# |tr \' _ \
# |tr \` _ \
# |tr \´ _ \
# |tr \' _ \
# |tr \& _ \
# |tr \* _ \
# |tr \# _ \
# |tr = _ \
# |tr + _ \
# |tr ? _ \
# |tr \\\\ _ )"
## # last line to get rid of "backslashes"...
# now for our final job output name:
outname=${jobid}_${printtime}_${sanitized_jobtitle}
# we include the $printtime part to have a uniq name in case the same job
# is tested with different settings to be kept for comparing. It is also
# useful for aligning debug efforts to CUPS' error_log entries.
# we will read the output directory from the printers $DEVICE_URI environment
# variable that should look s.th. like "2dir:/path/to/a/directory" and write
# our printfile as $outname there....
# Now do the real work:
case ${#} in
