all with 0 kb file size, so they provide no helpful information.

Is there some way to find out which process tries to call wget?
I checked some potential scripts but couldn't find the cause of the pollution yet.

Thanks for your help

best,
Sebastian

Re: [Solved] Home directory polluted by wget log files

I would set up an inotify handler to wait for access to /usr/bin/wget, then print the process that calls wget:

inotifywait -e access /usr/bin/wget && ps -u --ppid $(pgrep wget)

You may need to install the inotify-tools package if you haven't already.

--edit--
Wrong flags to `ps` - fixed.

--edit2--

Well, I was wrong, I'm sorry - I'll investigate a little more on that.

Re: [Solved] Home directory polluted by wget log files

What are your command line arguments to wget?
From man wget

 Logging and Input File Options
       -o logfile
       --output-file=logfile
           Log all messages to logfile.  The messages are normally reported to
           standard error.

           
Are you using o instead of O for out

-O file
       --output-document=file
           The documents will not be written to the appropriate files, but all will
           be concatenated together and written to file.  If - is used as file,
           documents will be printed to standard output, disabling link conversion.
           (Use ./- to print to a file literally named -.)

@teckk: I don't deliberately execute wget. It has to be called by some other process. But I don't know which one.

Re: [Solved] Home directory polluted by wget log files

wget will do this by itself, if for some reason it is backgrounded. Forgetting to properly quote urls that cointain a "&" can cause this to happen.

Re: [Solved] Home directory polluted by wget log files

Okay, i found the offender. Apparently, it was this line

External IP: ${exec wget http://ipinfo.io/ip -qO -}

in my conky config that caused the behavior.

Found it by executing

watch -n 1 'ps -xa | grep wget'

I don't know why I missed it before.

Sry and thanks all of you

best,
sebastian
