Can anyone tell me what's wrong with my script
Hi...

I am fed up in file handing with array for comparing....

1st I want save first 2 columns of file 1

I tried like this,,

Code:
{getline< "file1";ln[NR]=$1; lt[NR]=$2}

then I read second file's 1st and 2nd column..and saved like this
and small calculation and initialization
Code:
var1 =$1
var2 =$2
calc1= $2-0.1
calc2=$2+0.1
x=0
y=0

for loop for 2nd field of 1st and 2nd column...with a length of file 2's number of lines
Code:
for(j=1;j<=file2's length,j++)

now for loop like this for
Code:
(i=1;i<file1's array length;i++)

comparison
Code:
if lt[i] >=calc1 && lt[i]<=calc2

following if statements
else increment i and again check condition,

once i length reaches file1's array length

print file2's column fields..

then increment of j in 1st for loop

my script is having some mistakes...as I don't know much about either awk or shell...so I could not find where is problem....those who know, please solve my problem

Code:
c=`awk 'END{print NR}'file1`
awk '{{getline< "file1";ln[NR]=$1; lt[NR]=$2}}
FNR<=NR{
l1=$1;
la1=$2;
p=la1+0.1;
m=la1-0.1;
x=0;
y=0;
{
for(j=1;j<='$c';j++)
if(lt[j]>=m && lt[j]<=p)
{
if(l1>=ln[j])
x=x+1
if(l1<=ln[j])
y=y+1
}
}
if(x>=1 && y>=1)
print l1,la1,"Wow you are safe..."
}' OFS="\t" file2.dat

I hope you people understand this thread

tabs

TABS(1) 						    BSD General Commands Manual 						   TABS(1)

NAME

     tabs -- set terminal tabs

SYNOPSIS

     tabs [-n | -a | -a2 | -c | -c2 | -c3 | -f | -p | -s | -u] [+m[n]] [-T type]
     tabs [-T type] [+[n]] n1[,n2,...]

DESCRIPTION

     The tabs utility displays a series of characters that clear the hardware terminal tab settings then initialises tab stops at specified posi-
     tions, and optionally adjusts the margin.

     In the first synopsis form, the tab stops set depend on the command line options used, and may be one of the predefined formats or at regular
     intervals.

     In the second synopsis form, tab stops are set at positions n1, n2, etc.  If a position is preceded by a '+', it is relative to the previous
     position set.  No more than 20 positions may be specified.

     If no tab stops are specified, the ``standard'' UNIX tab width of 8 is used.

     The options are as follows:

     -n      Set a tab stop every n columns.  If n is 0, the tab stops are cleared but no new ones are set.

     -a      Assembler format (columns 1, 10, 16, 36, 72).

     -a2     Assembler format (columns 1, 10, 16, 40, 72).

     -c      COBOL normal format (columns 1, 8, 12, 16, 20, 55)

     -c2     COBOL compact format (columns 1, 6, 10, 14, 49)

     -c3     COBOL compact format (columns 1, 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58, 62, 67).

     -f      FORTRAN format (columns 1, 7, 11, 15, 19, 23).

     -p      PL/1 format (columns 1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 53, 57, 61).

     -s      SNOBOL format (columns 1, 10, 55).

     -u      Assembler format (columns 1, 12, 20, 44).

     +m[n], +[n]
	     Set an n character left margin, or 10 if n is omitted.

     -T type
	     Output escape sequence for the terminal type type.

ENVIRONMENT

     The LANG, LC_ALL, LC_CTYPE and TERM environment variables affect the execution of tabs as described in environ(7).

     The -T option overrides the setting of the TERM environment variable.  If neither TERM nor the -T option are present, tabs will fail.

EXIT STATUS

     The tabs utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     expand(1), stty(1), tput(1), unexpand(1), termcap(5)

STANDARDS

     The tabs utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     A tabs utility appeared in PWB UNIX.  This implementation was introduced in FreeBSD 5.0.

BUGS

     The current termcap(5) database does not define the 'ML' (set left soft margin) capability for any terminals.
