Header and trailer Check in UNIX

I am planning to automate multiple files through Unix script.

Could you please guide for making the automation for multiple files ?

Eg.

I have to check header and footer for all files in the particular path and the header pattern should match with the filename.
Code:
Filename- Filename.txt
Header - HEAD,filename.txt
1,Sumit,31,Delhi,,
2,Virat,33,Meerut,,
3,Amit,34,Jammu,,
Trailer -TRAIL,3

Also,I have to check header,trailer,file and header filename match,count check in trailer section,Total column check and not null check to automate the things.

I recommend coming up with something you've tried to move things along; otherwise, this seems a bit vague. For example, something like this....

Code:
find <particular-path> -name '*<some-common-pattern*' | while read a
do
filename_in_header=`head -1 ${a) | awk '{print $NF}'`
filename_in_trailer=`tail -1 {a} | awk '{print $NF}'`
.
.  <compare each of the above to the filename ${a} and then do whatever
.
done

This is just a simple example to illustrate what I mean by posting something you've tried.

Correct.
