6 pycdlib-explorer - tool to examine and modify ISOs using pycdlib
7
10 pycdlib-explorer <iso-file>
11
14 This is a tool to examine and modify existing ISO files on disk. Using
15 this tool, the files, directories, and metadata on an ISO can be exam‐
16 ined, new files can be added, and old files can be deleted. Note that
17 due to the nature of the ISO standard, files cannot be modified in
18 place in a general way. To accomplish this, remove the file and then
19 re-add it with new contents.
20 The commands that modify the ISO only modify the in-memory copy. No
22 changes are made to the original file until the write command is is‐
23 sued.
24 Also note that pycdlib-explorer has no command-line options; instead,
26 its behavior is controlled entirely at runtime through commands. The
27 following section describes the available commands in pycdlib-explorer.
28
31 add_file <iso_path> <src_filename> [rr_name=<rr_name>]
32 [joliet_path=<joliet_path>]
33 Add the contents of <src_filename> to the ISO at the location
34 specified in <iso_path>. If the ISO is a Rock Ridge ISO,
35 <rr_name> must be specified; otherwise, it must not be. If the
36 ISO is not a Joliet ISO, <joliet_path> must not be specified.
37 If the ISO is a Joliet ISO, <joliet_path> is optional, but
38 highly recommended to supply.
39 cd <iso_dir>
41 Change relative directories to iso_dir for exploration.
42 cwd Show the current working directory.
44 exit Exit out of pycdlib-explorer.
46 get <iso_file> <out_file>
48 Copy the contents of the relative or absolute ISO path iso_file
49 into out_file.
50 help Print the available commands. Use "help <cmd>" for a more de‐
52 tailed description of the commands, including the command-line
53 arguments they require.
54 ls Show the contents of the current working directory. The format
56 of the output is: TYPE(F=file, D=directory) NAME.
57 mkdir <iso_path> [rr_name=<rr_name>] [joliet_path=<joliet_path>]
59 Make a new directory called <iso_path>. If the ISO is a Rock
60 Ridge ISO, <rr_name> must be specified; otherwise, it must not
61 be. If the ISO is not a Joliet ISO, <joliet_path> must not be
62 specified. If the ISO is a Joliet ISO, <joliet_path> is op‐
63 tional, but highly recommended to supply.
64 print_mode [iso9660|rr|joliet|udf]
66 Change which 'mode' of filenames are printed out. There are
67 four main modes: ISO9660 (iso9660, the default), Rock Ridge
68 (rr), Joliet (joliet), and UDF (udf). The original iso9660 mode
69 only allows filenames of 8 characters, plus 3 for the extension.
70 The Rock Ridge extensions allow much longer filenames and much
71 deeper directory structures. The Joliet extensions also allow
72 longer filenames and deeper directory structures, but in an en‐
73 tirely different context (though in most circumstances, the
74 Joliet context will mirror the ISO9660/Rock Ridge context). The
75 UDF Bridge extensions add an entirely parallel UDF context to
76 the ISO as well. Any given ISO will always have ISO9660 mode,
77 but may have any combination of Rock Ridge, Joliet, and UDF (in‐
78 cluding none of them). Running this command with no arguments
79 prints out the current mode. Passing 'iso9660' as an argument
80 sets it to the original ISO9660 mode. Passing 'rr' as an argu‐
81 ment sets it to Rock Ridge mode. Passing 'joliet' as an argu‐
82 ment sets it to Joliet mode. Passing 'udf' as an argument sets
83 it to UDF mode.
84 quit Exit out of pycdlib-explorer.
86 rm_file <iso_path>
88 Remove the file named iso_path from the ISO. Note that this
89 must be a file; to remove a directory, use rmdir.
90 rmdir <iso_path>
92 Remove the directory named iso_path from the ISO. Note that
93 this must be a directory; to remove a file, use rm_file.
94 tree List the contents of the ISO in a tree-like format, similar to
96 the bash tree command.
97 write <out_file>
99 Write a valid ISO9660 file out to out_file, taking into account
100 any changes made while running the program. This is also some‐
101 times referred to as "mastering" the ISO. Note that the
102 out_file must NOT be the same file as the input file, or the re‐
103 sulting ISO will not work properly.
