expect script syntax problem

William Harris_3 — Tue, 03 Jun 2003 20:35:41 GMT

can someone help me find the correct syntax to the following? i'm trying to loop through the output of awk command.

foreach line [ awk '$4 == 103 && $9 !="*.rec" { print $9 }' incomingfiles.rec ].

thanks in advance,

chris

What about ..
..
awk '$4==103 && $9 !="*.rec" {print $9}' incomingfiles.rec | while read LINE
do
print $LINE
done
...

well it has been awhile and i don't have an expect installation for testing, but something like this should get you started.

your probably going to have to play with the quoting for the awk statement.

set input [open "| awk '$4 == 103 && $9 != \"*.rec\" {print $9;}' infile.rec " ]

while {[gets $input line] != -1} {
#do something with $line
puts "$line"
}
close $input

expect isn't really the problem here I would think... as suggested ... it's probably just your line or quoting...

you could try it like this
cat file |
while read line
do
echo $line | awk '$4 == 103 && $9 !="*.rec" { print $9 }' incomingfiles.rec
done
