FreeBSD 12.3 p5.

I'm trying to update Python py38 to py39 using this from the ports UPDATING section ...

The default version of python3 and python was switched to 3.9.

For ports users wanting to keep version 3.8 as default,
add DEFAULT_VERSIONS+= python=3.8 python3=3.8 to make.conf

Following procedures may ease the upgrade:

For users of pre-build packages:
# sh
# for i in $(pkg query -g %n 'py38-*'); do pkg set -yn ${i}:py39-${i#py38-}; d one
# pkg upgrade

For portmaster users:
# sh
# portmaster -o lang/python39 python38
# REINSTALL="$(pkg info -o "*py38*" | awk '{printf "%s ", $2}')"
# pkg delete -f "*py38*"
# portmaster $REINSTALL
# REBUILD=$(pkg query -g "%n:%dn" '*' | grep py3 | grep -v py39 | cut -d : -f 1 | sort -u)
# portmaster $REBUILD
# REBUILD2=$(pkg list | grep python-38 | xargs pkg which | awk '{print $6}' | sort -u)
# portmaster $REBUILD2

Final steps (for pre-built packages & portmaster):

If no longer required, Python 3.8 can be removed via
"pkg remove python38" and the directory /usr/local/lib/python3.8 can
then be deleted afterwards, if not empty.

However when I try to run REINSTALL="$(pkg info -o "*py38*" | awk '{printf "%s ", $2}')" I always get the error Illegal variable name..

I'm sure this worked fine from py37 to py38. Any suggestions.
 
It seems I have now inadvertently deleted all the py38 ports. No clue how it occurred but it has.

I've got a list of them in the logs. Is it a simple case of pkg install the py39 flavour now?
 
You forgot the sh and you were running it under csh (likely the result of su-ing to root).
Code: 
$ csh
% REINSTALL="$(pkg info -o "*py38*" | awk '{printf "%s ", $2}')"
Illegal variable name.

A more interesting question is how the heck does the quoting work in that statement. Why doesn't sh raise an error over the nested double quotes around "*py38*".
