Does any one have a better approach?

You mentioned in an adjacent post that you've not used AWK since 2000.
By contrast, I still use it regularly.

Hi
Hi to everyone I have an awk script that calculate minimum distances between
points
## atom type frag - atom type surface
#!/bin/bash
FILE1=$1.lammpstrj
if [ -f $FILE1 ];
then
awk 'function sq(x) {
return x * x;
}
function dist(x1, y1, z1, x2, y2, z2) {
return sqrt(sq(x1 - x2) + sq(y1
22 matches
