keep in mind that mass spawning of any bin is , when its done massley ,
very out ..
also var so awk processes some \esc caracters
to cleanly insert data , either use gawk ENVIRON["varname']
or via alternative fd or as part of file parse things
my='a b c'
# one line string
awk 3<<<"$my thing' BEGIN { f = "/dev/fd/3" ; getline v <f ; close( f ) }
other main code here '
foo=content
export foo
or foo=$foo gawk ..
gawk -vv=foo ' BEGIN { v = ENVIRON[ v ] } other code '
same as v = ENVIRON[ "v" ] or "varname"
to match in string , thers two ways , one is exact text match , the other
is regex
if u /foo/ thats a regex
$0 ~ "foo"
tx=" my text "
if ( $0 ~ "pre" tx "stu" ) { ye }
thers additional stuff to say containing substr() and match() , and some
others
#exact
etx = " exact "
if ( index( $0 , etx ) ) { ye }
if ( index( $0 , "pre" etx "stu" ) ) { ye }
j() {
