bitext_200601.txt:
200601

bitext_200602.txt:
200602

bitext_200603.txt:
200603

testaa.txt:
abcd200601  11111
abcd200602  22222
abcd200603  33333
abcd200604  44444
abcd200605  55555
abcd200601  66666
abcd200603  77777
abcd200601  88888
-------------------------------------------------------------------------------------------
程式:
re_file=$(ls bitext_??????.txt)
for file in $re_file
do
bcmonth=`cat $file`
echo $bcmonth
awk  '{if(substr($1,5,10)=='"'$bcmonth'"') print $2}' testaa.txt > testbb_${bcmonth}.txt
done

-------------------------------------------------------------------------------------------
希望得到結果 :
testbb_200601.txt :
abcd200601  11111
abcd200601  66666
abcd200601  88888

testbb_200602.txt :
abcd200602  22222


testbb_200603.txt :
abcd200603  33333
abcd200603  77777
-------------------------------------------------------------------------------------------
執行程式沒有結果,
請教要如何修改程式呢??

awk  '{if(substr($1,5,10)=='"'$bcmonth'"') ...
==>
awk  '{if(substr($1,5,10)=='"$bcmonth"') ...
