Let take this files for better understanding.

FileA
xyz, abc
ink, abc
iji, abc
klm, abc
tst, def
dev, ghi
prd, jkl

FileB:
abc, developer
abc, manager
xyz, developer
tst, developer
klm, developer
def, tester
ghi, integrator
jkl, analyst

Code:
awk -F", " '
NR==FNR{a[$1]=$2;next}
a[$2]{print $2 FS $1 FS a[$2]}
' OFS=", " FileB FileA

Expected output:
abc, xyz, developer
abc, ink, developer
abc, iji, developer
abc, klm, developer
abc, xyz, manager
abc, ink, manager
abc, iji, manager
abc, klm, manager
def, tst, tester
ghi, dev, integrator
jkl, prd, analyst


This will be the result if i import the FileA and FileB in two tables and join them on 2nd filed of FileA and 1st Field of FileB.

The problem with the array is it gets overwritten when same value is encountered for which array is being created.

Please let me know how to handle this.


Thanks a lot.

Beware of the order of the files:

Code:
awk -F", " '
NR==FNR{a[$1]=$2; next}
{ for(i in a) {
    if(a[i]==$1) {
      print $1, i, $2
    }
  }
}
' OFS=", " FileA FileB
