But awk only searches the first one and stops.
Of course it does:
Code:
awk -F'\t' 'NR==FNR{a[$1]=cnt++; next}{if($12 in a){printf "%05s\n", $2 > $1".pull";} }' /aiw/aiw1/pullfiles/*.txt *.dpf

The 'NR==FNR' bit is what tells awk to remember pattern ('a[$1]=cnt++') only from the first file.

You could do:
Code:
awk -F'\t' 'FILENAME~".txt$"{a[$1]=cnt++; next}{if($12 in a){printf "%05s\n", $2 > $1".pull";} }' /aiw/aiw1/pullfiles/*.txt *.dpf

Which instructs awk to apply the first action to *.txt files.
