shell之两个文档找出相同的之后在选

for i in `cat t1` ; do echo "$i" | awk '{sub(/^ */,"");sub(/ *$/,"")}1' >> tem1 ; done

for i in `cat t2` ; do echo "$i" | awk '{sub(/^ */,"");sub(/ *$/,"")}1' >> tem2 ; done

cat tem1 >> tem3
cat tem2 >> tem3

cat tem3|sort|uniq -c |awk '{if ( $1 > 1) print $2 }' > tem4

for i in `cat tem2`
do
FLAG=0

for j in `cat tem4`
   do
       if [ $i == $j ]
       then
           echo "$i found"
           FLAG=1
           break
       fi
   done

if [ ${FLAG} -eq 0 ]
   then
       echo "$i"
   fi
