Answer 1

下面的awk应该可以帮助您入门：

awk 'BEGIN {
  FS = "|"
 }
NR == FNR {
# while reading the 1st file
# store its records in the array f
f[$3] = $0
  next
 }
$1 in f {
# when match is found
# print all values
print f[$1], $0>   }' file1 file2


Red|Circle|123|apple|orange|grapes 123|Square|banana|blueberry

Red|Circle|123|apple|orange|grapes 123|Triangle|strawberry|grapes
