Janis, it looks this works:
ksh -c 'compound x=( a=1 typeset -a ar=( 8 9 10 ) b=2 i="( bello=hello
)" compound c=( typeset -a ar=( 1 2 3 ) d=6 e=9 ) ) ; print -v x' |
/usr/xpg4/bin/awk '/^\t[^\t]/ && sub(/=.*/,"")'
a
typeset -a ar
b
typeset -a c
i
Thank you.
Now I need some thing which does not use a pipe and awk. I will try
with ~(Ems) pattern (extended regular pattern, allowing matches for
newline in spans) and .sh.match
