output awk print horizontally

output awk print horizontally

(OP)
Hello

I did a search of the forum but couldn't find my answer.

I'm tracking parent and child processes that I want my child pids to be listed horizontally
instead of vertically. I attempted to insert a tab but this is not working.

MYPID="$$"
echo "PPID: ${MYPID}"

CHILDPIDS=$(ps -ef -o user,pid,ppid |grep ${MYPID}| awk '{print "\t"$2}'
echo "Child PIDS: $CHILDPIDS"

so that my output comes out like so:

PPID: 0001
Child PIDS: 1001 1002 1003

Thanks for any insight
