How to compare two files ?

Hi am just trying to compare two files data...

datafile1 is standard data, datafile 2 is varying

Code:
st_data.txt
Code:
long      lat
68.14    23.48
67.56    22.99
67.08    22.49
66.79    22.25
66.68    22.18
66.07    21.89
65.67    21.65
65.6    21.56

Code:
un_std.txt
long     lat
75.5    10.05
75.02    10.15
74.52    10.23
74.02    10.33
73.45    10.43
73.15    10.48
2.1    10.55
74.15    8.9
72.73    10.53
72.98    10.43
73.52    10.23

here I want to compare like this

Code:
if un_std data file's long and lat is less than or equal to std_data file's long and lat write "YES"(within region) to particular row else "NO"(outside region) corresponding row,

here I want to cross check a single entry of un_std file with all entry's of std_file if condition meets, then to write yes or no

Once more, your problem is not explained in an "understandable" way.

Should "long" and "last" be considered independantly ? so yes or no should be displayed once per column (see example below) ?

or should the sum of them be considered for the comparison ?

if you have st_data.txt :
Code:
long      lat 
68.14    23.48

un_std.txt
Code:
long     lat 
75.5    10.05

What output do you expect ?

Code:
long lat
no   yes

or
Code:
long+lat
yes

or something else ?

for instance I want to check, first lat of un_std file with std_lat(all entry), that, whether its less than or equal lat of std file, if check passes, then compare long of un_std with std_data(all entry), if both passes write Yes, otherwise No

Code:
awk 'NR==2{g=$1;t=$2}(NR==FNR){g=(g+0<=$1?g:$1);t=(t+0<=$2?t:$2);next}FNR==1
{print $0;next}$1<=g&&$2<=t{print $0 FS "yes";next}{print $0 FS "no"}' st_data.txt un_std.txt

Thanks for your reply, kindly check std_data file in code by copying to some other,,and try. I think I need to use some trigonometric tricks for this,..

Can anyone able to convert this to shell...

Code:
do 20 i=1,var
        lat2=0
        lon2=0
        k=0
        c=0
        c=0
        d=0
        if(instr(i)=='abc')then
        do 21 j=1,var1
        if(lat1(j).ge.lat(i)-0.1.and.lat1(j).le.lat(i)+0.1)then


        if(lon(i).ge.lon1(j))then
        c=c+1
        endif        
        if(lon(i).le.lon1(j))then
        d=d+1
        endif
        endif
 21     continue 
        endif      

        if(c.ge.1.and.d.ge.1)then

        write(13,'(a70)')dat(i)

        endif
               
 20     continue

Code:
here lat(i) lon(i) is from 1st file(standard file) 2nd and 1st column respectively, and lat1(i) lon1(j) is from file to be checked (2nd file)...2nd and 1st column...
