次のbashコマンド（Ubuntu 18.04で実行）は、各XRDPセッションの解像度（形状）を除いて、必要なXRDP情報をテーブルに表示します。
{ echo "user pid Xdisplay port"; { ps -ef | awk '/Xvnc :[[:digit:]]+/ {print $1,$2,$9}' | while read tu tpid tvnc; do sudo netstat -tlpn | awk -v "tpid=${tpid}" '$0 ~ tpid {print $4;}' | sed -r -e 's/^.*://;' -e "s/^/${tu} ${tpid} ${tvnc} /;" ; done ; } | sort -k3 ; } | column -c4 -t
たとえば、出力を提供します。
user pid Xdisplay port
baz 127229 :11 5911
bar 27817 :12 5912
baz 48659 :13 5913
ユーザー名、pid、Xdisplay、およびポート番号の既存の詳細に加えて、RDPセッション解像度（形状）を表示するためにどのように使用できますか？

答え1
次のことを証明するためにcat netstatout代わりに使用する：sudo netstat -tlpncat psoutps -ef
$ cat tst.awk
BEGIN {
OFS = "\t"
print 0, 0, "user", "pid", "Xdisplay", "port", "geometry"
}
NR==FNR {
port = $4; sub(/.*:/,"",port)
pid = $NF; sub("/.*","",pid)
pid2port[pid] = port
next
}
/Xvnc[0-9]* :[[:digit:]]/ {
port = pid2port[$2]
match($0,/geometry [^ ]+/)
geometry = substr($0,RSTART+9,RLENGTH-9)
display = $9; sub(/:/,"",display)
print 1, display, $1, $2, $9, port, geometry
}
。
$ awk -f tst.awk <(cat netstatout) <(cat psout) | sort -k1,1n -k2,2n | cut -f3- | column -t
