How to retrieve string which does not contain '$'?

Hi,

I have a file say file1.ksh. Which has data like:

Code:

ifile $AI_SERIAL/$FILE.DAT...
ofile $AI_SERIAL/feed.dat...

My requirement is to find the count of all the lines which does not have $ after /. So i have written the code:

Code:

 
grep -w 'AI_SERIAL' file1.ksh | cut  -d '/' -f2 | grep -vc '\$'

when i run this script , it is giving me correct answer : 1

but when i do :

Code:

 export key=`
grep -w 'AI_SERIAL' file1.ksh | cut -d '/' -f2 | grep -vc '\$'`
echo $key

it is returning 0. Could you please help me in this?

Code:

sed -n '/\/[^\$]/p' input_file

For getting the count...

Code:

sed -n '/\/[^\$]/p' input_file | wc -l

Urgent: How to retrieve string which doesnot contain '$'?

I have tried :

export key=`grep -w 'AI_SERIAL' file1.ksh | cut -d '/' -f2 | grep -vc "./$."`
set -a $key
echo $key

it is returning 2 but it should return 0.

---------- Post updated at 02:36 AM ---------- Previous update was at 02:32 AM ----------

I tried:

export key=`grep -w 'AI_SERIAL' file1.ksh | cut -d '/' -f2 | fgrep -v "/$" | wc -l`

but again it is returning 2 whereas i want only the lines which does not have file name without $.
