bplist output fields?

dmj12031 - why not submit to enhancement to documentation -

I'm sure this can now be included...

Sorry dmj - it wasn't as easy as I'd hoped :)  I've put some feelers out to other folks to see if I can find an "official" answer for you.

My educated guesses from poking around - and after you already did most of the heavy lifting:

Fields 1-4 appear to be used to specify sizes under certain conditions, but are unused with straight file backups.  They are taken in pairs - one is gigabytes and the other is the remainder - you add 'em to get the final size.  All this is moot as they were always 0 in my tests and I don't think you'd ever get nonzero results from the command line.  :)

Field 5 is the file size in bytes, as you have already figued out.

Fields 6 and 7 file and block numbers and go with the device number in field 8, which you have already figured out.

Field 9 is a "this file is in the image" flag, looks like.  (It was always 1 whenever I tested it out, which makes sense)

I never would have figured out field 10 in a zillion years - fortunately you already figured out it was the permission.  :)

Fields 11 and 12 are obviously user and group, as you have already figured out.

Field 13 looks like file size in bytes again.  It's possible that if you're using compression, this one (or field 5) would change to the compressed file size in bytes, but that's a REAL reach of a guess from me.  I probably shouldn't assume there's an actual reason for listing the bytes twice :)

Fields 14-22 are pretty much exactly as you have already figured out.

Finally, it doesn't look like this output has changed much (at all?) from the time it was introduced in 5.x through 7.x.

Hope this helps!  If I find out anything more "official," I'll be sure to share it - thanks for the interesting question!

 

Thanks CRZ, much appreciated.

play detective."

Where's the fun in that?

***EDIT***

Maybe you're right, it isn't fun....you've got a lot further than I think I'd've managed.

If you provide the version info CRZ requested I'm sure he'll do the business for you!

Give me a version number and I'll see if I can suss this out for you.

Looks like it's very similar to bpflist (which makes sense), albeit in slightly different order...

field 8 is encoded major/minor dev number (-2147480663 above is an NFS mount)

field 10 is mode bits in decimal (33188 above = 100644 octal = reg file mode 644)

field 18 is schedule type (4 above = Cumul INCR)

Still would like to find this documented somewhere, rather than play detective.

field 19 is length of policy name (16 in example above)

field 21 is length of file/path name (41 in example above)

Going to have to try this when I'm back at work & can try it on somthing specific there.

Looking at the man page doesn't divulge much:

filename
Names the file or directory to list. If you do not specify a path, the default is the current working directory. Any files or directories that you specify must be listed at the end, following
all other options. For directories, if you do not use the -R option, include the trailing path
separator as in the following: bplist -l "/home/user1/*" Note: If you use the asterisk meta character "*", you should use quotation marks around the filename for the command to work properly.

-Listpolicy
Includes the schedule type and policy name in the command output.

Sorry, should have been more specific, I'm looking for an explanation of the bplist output fields when using the -Listpolicy flag.  Some are obvious, some not so much; I assume one of the 0's is policy type.

Example (output fields on separate lines for readability:)

$ bplist -Listpolicy -s <start date> <file name>

Thanks

a) the command string you are using &

b) the output it generates with an explanation of what you don't understand.

We could then try & assist you specifically.
