This is the old script I had under ReadyNAS, which was a Debian base, if I remember correctly.  Obviously, the URL and path(s) would change, but the rest of the syntax is where I am clueless.

wget --keep-session-cookies --save-cookies /home/admin/cookies.txt --delete-after --post-data="username=cron&password=RwpJYB^Zz#mQ^6" "https://gjschaller.homeftp.net/piwigo/ws.php?format=json&method=pwg.session.login"

wget --load-cookies /home/admin/cookies.txt -nv -O missing.json "https://gjschaller.homeftp.net/piwigo/ws.php?format=json&method=pwg.getMissingDerivatives"
while [ `wc -c missing.json | cut -f 1 -d ' '` -gt 50 ]
do
  sed -e 's/[\\\"]//g' \
  -e 's/{stat:ok,result:{next_page:[0-9]*,urls:\[//' \
  -e 's/{stat:ok,result:{urls:\[//' \
  -e 's/\]}}/\n/' \
  -e 's/,/\n/g' \
  -e 's/\&b=[0-9]*//g' missing.json | \
  while read line ; do
    wget -nv -O /dev/null $line
  done
  wget --load-cookies /home/admin/cookies.txt -nv -O missing.json "https://gjschaller.homeftp.net/piwigo/ws.php?format=json&method=pwg.getMissingDerivatives"
done

rm /home/admin/cookies.txt

Thank you for any help and advice!

Heh, I forgot that was in there, in plain text - that's been changed.

OK, so I modified the script to work under the FreeBSD file system, running as root.  I made sure wget was installed, and now have some progress.  The new script:

wget --keep-session-cookies --save-cookies /root/cookies.txt --delete-after --post-data="username=cron&password=REDACTED" "https://photos.aiskon.net/piwigo/ws.php?format=json&method=pwg.session.login"

wget --load-cookies /root/cookies.txt -nv -O missing.json "https://photos.aiskon.net/piwigo/ws.php?format=json&method=pwg.getMissingDerivatives"

while [ `wc -c missing.json | cut -f 1 -d ' '` -gt 50 ]
do
  sed -e 's/[\\\"]//g' \
  -e 's/{stat:ok,result:{next_page:[0-9]*,urls:\[//' \
  -e 's/{stat:ok,result:{urls:\[//' \
  -e 's/\]}}/\n/' \
  -e 's/,/\n/g' \
  -e 's/\&b=[0-9]*//g' missing.json | \
  while read line ; do
    wget -nv -O /dev/null $line
  done
  wget --load-cookies /root/cookies.txt -nv -O missing.json "https://photos.aiskon.net/piwigo/ws.php?format=json&method=pwg.getMissingDerivatives"
done

rm /root/cookies.txt

The output when I run it:

root@piwigo:~ # ./piwigo-generate.sh

[: -gt: unexpected operator

So it looks like it's failing on the "While" line of the script?

Thank you, this is helpful!

It looks like they're installed, and wc works.  cut doesn't give expected output - I did install it via pkg install cut, then re-ran the test, this is what I have:

(MOTD Text)
root@piwigo:~ # [ 100 -gt 50 ] && echo yes
yes
root@piwigo:~ # wc -c /dev/null
       0 /dev/null
root@piwigo:~ # wc -c /dev/null | cut -f 1 -d ' '

root@piwigo:~ #

Thank you for your help on this - if I need to move this over to a FreeBSD support forum, I can.

Thank you.  Making sure I'm not making any mistakes, the full line would be:

while [ `wc -c missing.json | awk '{print $1}'` -gt 50 ]

I'm still new to FreeBSD and my linux is rusty, so I want to be sure I've got all the syntax correct with another set of eyes.

Thank you!

I realized I had a wrong URL in there - the "(domain)/piwigo/" was from the old NAS, once I updated with your syntax and corrected the URL, it seems to be working!
