Yes, I don't think it will work as what you have posted in the first post.
Try this...
Code:
for ff in `seq 3 $nlpN`;
do
  val=( $(awk 'NR==ff {print $1" "$2" "$3" "$4}' ff=$ff p_walls.raw) )
  npc1[$ff]=${va[0]}
  npc2[$ff]=${va[1]}
  npc3[$ff]=${va[2]}
  npRs[$ff]=${va[3]}
done

What is it that you are actually looking for?... You asked to optimize your code, we did without losing the functionality. If your requirement is something else, please provide more clarity and if possible some input and expected output etc

now im embarrassedSmilie yeah the code is optimized and i thank you a lot.. i just wanted to make it even faster by invoking awk just once per file..

the option provided is was faster already, but i'm greedy and i want to make it even faster.. Smilie



i wanted to open the file,
then
do the loops and the operations
then
close the file

i didnt wanna loop the awk command. that's why i wanted to have sth like (This is not the code, just grab a look at the syntax and order)
https://www.unix.com/shell-programmin...-question.html
Code:
awk '
{        for (i=1;i<=NF;i++) 
         {if ( i > 8 )
          printf("%s ",$i)                        
          else                            
          printf("%s|",$i) } 
          printf("\n") 
}'   p_walls.raw

once again ty!

the input is like

*.inp file is like
Code:
17,   3.22854114,  0.562598288,  0.384291202
     18,   2.96085286,  0.085116826,  0.285071939
     19,   3.40070796,   2.27838659,  0.302027524
     20,   3.20035744,  0.333615214,  0.262585849
     21,   2.85644341,  0.258691043,  0.369726121
     22,   3.73537922,    1.3267405,  0.295917094

     25,   3.27523994,  0.695856452,  0.377585977

*.dat file is like
Code:
      25169     -3.8128E-09  3.7586E-10  6.3384E-08 
      25170     -3.8339E-09  3.7958E-10  6.3555E-08 
      25171     -3.8549E-09  3.8382E-10  6.3723E-08 
      25172     -3.8757E-09  3.8828E-10  6.3888E-08 
      25173     -3.8965E-09  3.9323E-10  6.4049E-08 
      25174     -3.9173E-09  3.9872E-10  6.4207E-08 
      25175     -3.9384E-09  4.0454E-10  6.4363E-08


and theres no output atm.. im assigning vars with this code Smilie

the problem is.. my loop is 100k+ passes long

and i have this:
Code:
...

echo $f
done

i'm opening each one of the 2 file 4 times... thats time consuming... can any warlock around make it so that i open each file just once? i'm digging but i rly dont have that much time... yeah we always w8 til last minute :P i believe i may eventually come up with sth.. but i thought i could ask you guys this

once again.. thx.. this forum is rly alive! Smilie)

---------- Post updated at 02:24 PM ---------- Previous update was at 12:25 PM ----------

i am looking 4 sth similar to:

Code:
awk '{
        dataI=''NR=='$f' { print  $2 $3 $4; exit } ''
		
      	noD1[$f]=`echo "$dataI" | cut -f1 -d ','`;
	noD1i[$f]=`echo "$nlinpN1 + ${noD1[$f]}"|bc -l`; 
	dataIi=''NR=='${noD1i[$f]}' { print  $2 $3 $4; exit }''
	
	noD2[$f]=`echo "$dataI" | cut -f2 -d ','`; 
	noD2i[$f]=`echo "$nlinpN1 + ${noD2[$f]} "|bc -l`;
	dataIii=''NR=='${noD2i[$f]}' { print  $2 $3 $4; exit }''	
	
	noD3[$f]=`echo "$dataI" | cut -f3 -d ','`; 
	noD3i[$f]=`echo "$nlinpN1 + ${noD3[$f]} "|bc -l`;
	dataIiii=''NR=='${noD3i[$f]}' { print  $2 $3 $4; exit }''	
	}' <aoa_5.inp;

so far im trying to debug thou im not sure ill get somewhereSmilie

---------- Post updated at 04:38 PM ---------- Previous update was at 02:24 PM ----------

or maybe sth like this,,,

Code:
       awk  '  
	    
	'$f'  {
                dataI2[$f] = $2;
		dataI3[$f] = $3;
		dataI4[$f] = $4;
		noD1[$f] = $dataI1[$f];
		noD2[$f] = $dataI2[$f];
		noD3[$f] = $dataI3[$f];
		noD1i[$f] = $nlinpN1 + $dataI1[$f];
		noD2i[$f] = $nlinpN1 + $dataI2[$f];
		noD3i[$f] = $nlinpN1 + $dataI3[$f];
		}	
	'${noD1i[$f]}' { 
		dataIi2[$f]=$2;
		dataIi3[$f]=$3;
		dataIi4[$f]=$4;
		}
     
	'${noD2i[$f]}'	{ 
		dataIii2[$f]=$2;
		dataIii3[$f]=$3;
		dataIii4[$f]=$4;
		}
		
	'${noD2i[$f]}'	{ 
		dataIiii2[$f]=$2;
		dataIiii3[$f]=$3;
		dataIiii4[$f]=$4;
		}
			          
	' <aoa_5.inp;
