Bash script is not working on many files by using for loop

Question

This is my script:

#!/bin/bash
SOL_atom_index=116101
number=1
SOL_mol_index=SOL$number
index=1
for index in {1..100}
do
    for SOL_index in {116101..136845}
            


        

Answer 1

Use ls with wildcard eg:

for eqfile in `ls -l /*.ndx`
   do
     sed -i "s/$SOL_atom_index/$SOL_mol_index/g;s/$(($SOL_atom_index+1))/$SOL_mol_index/g;s/$(($SOL_atom_index+2))/$SOL_mol_index/g" $eqfile 
   done
