Shell Programming and Scripting

Hello everyone

I have a few hundreds of .mol2 files that has this pattern

Code:

 
    @<TRIPOS>ATOM
      2 H18 65.2220 Du 1 RES1 0.0000
    @<TRIPOS>BOND
     1  3  5  ar
    @<TRIPOS>SUBSTRUCTURE

among them, some of the files are missing the line after the @<TRIPOS>BOND and they look like

Code:

    @<TRIPOS>ATOM
      2 H18 65.2220 Du 1 RES1 0.0000
    @<TRIPOS>BOND
    @<TRIPOS>SUBSTRUCTURE

I'm trying to find all the files in my working directory that are missing the numeric line after the `@<TRIPOS>BOND` and move them to another directory. I know this is a simple task, but I am quite new to Linux.
Here's one of my codes, which I was planning to write in a for loop. It doesn't do the job, but I am showing it to show one of my trials.

Code:

for i in *.mol2; do cat $i | grep -A1 '@<TRIPOS>BOND' | awk 'FNR == 2 {print}' | awk '$1 ~ /^@/' ; done

I know my code is really inefficient, but I am not an expert with Lunix at all.

Appreciated.

One way

Code:

awk '/@<TRIPOS>BOND/ {getline;if ($0 ~ /@<TRIPOS>SUBSTRUCTURE/) {print FILENAME;exit}}' *.mol2

All it does is, checking for @<TRIPOS>SUBSTRUCTURE just after @<TRIPOS>BOND. If it finds, it will pass the criteria.

perfect, I had to remove the 'exit' part to make it run for the whole directory. Thanks for your help
