Wanted to count the lines between ~Curve Information Block and ~A
and i need a count of no of lines between these two.
I need an output file with the filename and the no of lines present between these 2 pattern.
The no of lines between these patterns can vary.........
I need to do this for morethan 1000 files............
I belive an awk code or Shell script can help me in this..........

Thanks in advance..........

this can help you:

echo "" >OutputFile

for file in UrDirPath/*

NOL=`awk '/~Curve/,/~A/ {print}' InputFile|wc -l`
echo "$file $NOL" >>OutputFile

root@isau02:/data/tmp/testfeld> cat weekend_is_close.ksh
awk -v filename=$1 '
        /^~Curve Information Block/ {
                while ( ! /^~A/ ) {
                        #print $0
                print filename"_"i
' $1
root@isau02:/data/tmp/testfeld> ./wee*.ksh infile

If you want the filename and the line number added continously to a single file, just redirect the output with >> into a file and change the behaviour for the parameter.

Another one:

awk '/^~Curve/ { close(f); c = 1 } 
/^~A$/ { print FILENAME, c - 2 > (f = FILENAME "_done") }
c { c++ }' filename1 [filename2 ... filenamen]

Use nawk or /usr/xpg4/bin/awk on Solaris.

I'm not sure if you want the number of lines as a filename or a file content.

Just realized that probably you want something like this:

awk '/^~Curve/ { c = 1 } 
/^~A$/ { print FILENAME, c - 2 > "all_count" }
c { c++ }' filename1 [filename2 ... filenamen]
