The catalog command is accessed with either ”-c” or ”—catalog”.
Here is an example, showing the contents of an ADTPro disk image:
jonno@ubuntu:~/ADTPro-1.0.3/disks$ dsktool.rb --catalog ADTPRO-1.0.3.PO ADTPRO-1.0.3.PO sector order: physical filesystem: prodos volume name: ADTPRO.1.0.3 12544 SYS : $2000 ADTPRO 13428 SYS : $2000 ADTPROAUD 15365 SYS : $2000 ADTPROETH 10240 SYS : $2000 BASIC.SYSTEM 16509 SYS : $0 PRODOS 1220 BAS : $801 STARTUP jonno@ubuntu:~/ADTPro-1.0.3/disks$
Here’s another example, which demonstrates that dsktool can access images hosted remotely (by providing the full URL) and also how dsktool can handle images compressed with gzip :
jonno@ubuntu:~/ADTPro-1.0.3/disks$ dsktool.rb -c http://jamtronix.com/dsks/apshai.dsk.gz http://jamtronix.com/dsks/apshai.dsk.gz sector order: physical filesystem: dos B 0256 ASCII *B 2304 DATA1 *B 2304 DATA2 *B 2304 DATA3 *B 2304 DATA4 *A 13312 DM A 0256 HELLO A 0256 HELLO.OLD *A 17408 INN *B 0768 OBJ.1 *B 5888 OBJ.2 B 2304 SHAPE1 B 2304 SHAPE1.OLD B 2304 SHAPE2 B 2304 SHAPE2.OLD B 2304 SHAPE3 B 2304 SHAPE3.OLD B 2304 SHAPE4 B 2304 SHAPE4.OLD B 2560 TEMPLE OF APSHAI RWTS *A 4352 TITLE B 0512 TITLESHAPES jonno@ubuntu:~/ADTPro-1.0.3/disks$
