Shell Programming and Scripting

yes, same directory has all the files.

A files are named as : npkf_123,
qb5f_123
and list1 consists the names of all these files.

whereas, B files are named as : mist_npkf,
mist_qb5f etc
and list2 consists the names of all B files.

I have created the above given shell in the same directory...

list1 and list2?

Post some lines of those files and please use code tags when posting code or data examples.

Assuming the name of a Bfile is "mist_" and the part before the "_" of the Afile:

Code:

while read Afile
do
  file=${Afile%_*}
  Bfile="mist_"$file
  awk 'NR==1{s=$1; next}
  $2=="BBM" && $5==s {print $4}' $Afile $Bfile > $file"456"
done < List1

Hi franklin,

The above code gives the error :

Hi.

I imagine this line:

Code:

Bfile="mist_" file

should be:

Code:

Bfile="mist_"$file

hi,
the above code is also giving the error
Whereas, B files are starting with "dist_", i cant understand, wotz the problem....
