I have noticed on my Arch Linux (with GNOME 3.24.2 and GDM) installation that my ~ is filled with files like this and they keep increasing:

-rw-r--r--   1 root root    0 May  8 00:01 wget-log
-rw-r--r--   1 root root    0 May  8 00:01 wget-log.1
-rw-r--r--   1 root root    0 May  8 00:01 wget-log.2
-rw-r--r--   1 root root    0 May  8 00:01 wget-log.3
-rw-r--r--   1 root root    0 May  8 00:01 wget-log.4
-rw-r--r--   1 root root    0 May  8 20:04 wget-log.5
-rw-r--r--   1 root root    0 May  8 20:04 wget-log.6
-rw-r--r--   1 root root    0 May  8 20:04 wget-log.7
-rw-r--r--   1 root root    0 May  8 20:04 wget-log.8
-rw-r--r--   1 root root    0 May  8 20:04 wget-log.9

In fact, there would be more if I didn't delete them every day. I have noticed these files appearing after running sudo pacman -Syu, but I have also observed them not appearing after doing so so perhaps it was just coincidence? But I would really like to track down the cause of these empty log files appearing in ~ as they are actually quite annoying and seem to serve no real purpose.

So what are they caused by and is there any way I get either stop them from appearing or have them do so in a different location?

  • Do you have sysdig? If so, run sudo sysdig -p "%proc.pname(%proc.ppid) %proc.name(%proc.pid)" "fd.name contains wget-log" and see what process is poking those files. – thrig May 8 '17 at 19:29

    My guess is you have a cron job that runs every day at 0:00 and 20:00 and does some kind of wget. – Barmar May 8 '17 at 19:49
  • @thrig: Seems to be a problem with that, I have updated my question to provide more information. – user103789 May 8 '17 at 20:02
  • @thrig: It appears as though the sysdig DKMS module now builds successfully so I will try running it and let you know of the results. – user103789 May 27 '17 at 9:19
  • @thrig: It's been running now for a few hours and still no output. How long is this command expected to run for? – user103789 May 29 '17 at 11:36

This looks like a bug, a regression from wget 1.18 to wget 1.19.1 which is used by Arch Linux. I have opened a bug report here: https://savannah.gnu.org/bugs/?51181

This bug is fixed in Wget 1.19.3, released on 19 January 2018.
