- Delete pages 1-42
for i in $(jot 42 1) ; do djvm -d file.djvu 1 ; done
- Delete pages 441-449
count=441 ; until [ $count -gt 449 ] ; do djvm -d file.djvu 441 ; count=`expr $count + 1` ; done
- Delete even pages 204 to 2
for (( COUNTER=204; COUNTER>=2; COUNTER-=2 )) ; do djvm -d file.djvu $COUNTER ; done
- Delete odd pages 329 to 105
for (( COUNTER=329; COUNTER>=105; COUNTER-=2 )) ; do djvm -d file.djvu $COUNTER ; done
