Hello Jan
This is my script running under OS/2-eComStation:
/* begin of CMD file */
/* access with WGet */
'wget -i oscarkep.url -O kepler-w.txt'
/* file with URL's */
/* access with Curl */
'curl -c cookies.txt -b cookies.txt -k
https://www.space-track.org/ajaxauth/login -d
"identity=USER&password=Pa$$w0rd"'
/* login via cookie */
'curl --cookie cookies.txt -k
https://www.space-track.org/basicspacedata/query/class/tle_latest/favorites/al
l/ORDINAL/1/format/3le
-o kepler-c.txt'
'copy kepler-w.txt + kepler-c.txt kepler.txt'
/* end of CMD file */
May it help.

Here is a bash script that might be of help:
--------8<--------
#!/bin/bash
CAT=/usr/bin/cat
RM=/usr/bin/rm
WGET=/usr/bin/wget
GREP=/usr/bin/grep
VERBOSE=1
# change these to suit your taste
OUTPUT=${HOME}/MySatellites.tle
MATCH=${HOME}/Sats_I_Like.txt
# delete existing output file
if [ -f ${OUTPUT} ]; then
[[ $%{VERBOSE} ]] && echo "Deleting ${OUTPUT}"
${RM} ${OUTPUT};
fi
# heredoc contains URLs of interest. Edit to suit yourself
[[ $%{VERBOSE} ]] && echo "Fetching elements from www.celestrack.com"
${CAT} << EOF | while read URL
http://www.celestrak.com/NORAD/elements/amateur.txt
http://www.celestrak.com/NORAD/elements/weather.txt
http://www.celestrak.com/NORAD/elements/visual.txt
EOF
do
[[ $%{VERBOSE} ]] && echo "-- ${URL}"
${WGET} -q ${URL} -O - | ${GREP} -A 2 -f ${MATCH} >> ${OUTPUT}
done
[[ $%{VERBOSE} ]] && echo "Done."
-------->8--------
This will fetch one or more element files from celestrack (you say which
URLs to use in the heredoc) and pick out satellites of interest to you
by name, combining the results into a single output file. You specify
the satellites you want in a match-file (name defined at the top of the
script) and similarly the name of the file where you want the results put.
Two cautions: 1) be careful with your matches. "AO-7" matches with
"AO-71" too. And 2) if a satellite appears in more than one input file,
it will appear more than once in the output. (Example, ISS (ZARYA)
appears in amateur.txt and visual.txt.)
You could change a few things -- select by satellite number & designator
rather than name, for instance, or read URLs from an external file. Or
have the heredoc also specify the name of the output file for each input
URL. But for anything much fancier than this (like sorting the output
by satellite name, skipping duplicates, anything but the simplest of
command-line arguments, etc) I'd go with a perl script.

Hmmm.
I don't know how or why, but all my VERBOSE shell variables seem to have
acquired an unnecessary percent sign.
The script will still run as-is, but please remove those unwanted %age
symbols if you decide to try this script.
Thanks...

Good to see another new company hoping to provide small satellite launches,
this one is aiming at the 2017+ timeframe.
