Wrapper around `wg show` that uses pivpn configuration names instead of peer ids

pivpn-wg-show.sh

#!/bin/bash
#
# Beautifies output of `wg show` using config names from pivpn
#

wg show | awk "BEGIN { $( 
  # Map peer to preshared key
  wg show all preshared-keys | awk '{ print "key[\"" $2 "\"] = \"" $3 "\";" }'
  for f in $( ( . /etc/pivpn/wireguard/setupVars.conf ; echo $install_home ) )/configs/* ; do
    # Map preshared key to config name
    printf 'name["%s"] = "%s";\n' \
      "$( cat $f | grep PresharedKey | sed 's/.*= //' )" \
      "$( basename $f | sed 's/.conf$//' )"
  done
) } /peer/ { print name[key[\$2]] ; next } { print \$0 }"
