Shell script to clean (redact) log files before posting


#21

Thanks!

You’re right,

I used your script on my Mac where I copied the log.txt but the config.xml on the Mac does not have that device mentioned… So my bad, sorry.

Maybe a short message at the end of the script’s execution should warn users like me, that not all was sanitized?.. :-}


#22

Hmm, the thing is that it knows “what should be sanitized” based on the config…

I can add a warning for the un-cleared long ID formats (i.e. IDIDID-IDIDID-IDIDID-IDIDID…), since it has a distinct pattern, but I can’t do anything about other such stuff, like folder/device names, partial IDs, etc. since there’s no (known to me) way to accurately detect them without knowing them in advance first.


#23

I see, thanks for explaining.

Well, its better than nothing!

I have another/unrelated question:

Would you mind to add an additional “modus” to your script to just redact the given config.xml ? (Or maybe a question to the user, if the config.xml should also be redacted)

Pre-posting my config, I need to search/replace it manually like:

<configuration version="27">
<folder id="my private folder id" label="my private label" path="my private path" type="readonly" rescanIntervalS="10800" fsWatcherEnabled="true" fsWatcherDelayS="60" ignorePerms="true" autoNormalize="true">

to

    <configuration version="27">
    <folder id="F1" label="L1" path="P1" ...

for the first folder.

For the second folder, I do

<folder id="F2" label="L2" path="P2" ...

etc.

For the Devices, I do similar seearch/replace:

<folder id="F1" label="L1" path="P1" type="readonly" rescanIntervalS="10800" fsWatcherEnabled="true" fsWatcherDelayS="60" ignorePerms="true" autoNormalize="true">
        <filesystemType>basic</filesystemType>
        <device id="DDDDDD-DDDDDD-DDDDDD-DDDDDD" introducedBy=""></device> 

to

<folder id="F1" label="L1" path="P1" type="readonly" ...>
<filesystemType>basic</filesystemType>
<device id="D1" introducedBy=""></device>

Your script could help here to speed up the process and generate a ready2go config_redacted.xml

It might be a simple check first on how many folders/devices are present in the config and then replaceing the strings for each device/folder.

That would be a great enhancement.

Example: https://pastebin.com/zsKPFVgj (but I was too lazy with the paths…)


#24

Oh, another thing.

Reading the redacted logs, I think, they’re not very well readable, because of the looong Device IDID-IDID-IDID-IDID_n’s.

Would it be possible to define just a “ID_n” instead of IDID-IDID-IDID-IDID_n" ?

And the is a small ‘l’ after the folder label. Is this correct?

better readable, IMHO

#25

Redacting xml config is an easy thing to add. I can pass it through the same procedure as the log files.

As for redact format - i.e. FOLDER_ID_# vs FID_#, I actually prefer the longer one, as FID isn’t as obvious to what it stands for in my opinion.

The IDID-IDID-IDID-IDID can be improved however.

Side note - since there’s some “action” with this tiny tool, I put it on GitHub to track issues/requests, etc. You can chime in there if you like:
