Hi,

I am trying to something similar but not really...

there are three arrays:

@array1 = ('Leishmania infantum','Leishmania donovani','Leishmania pan
+amensis','Leishmania braziliensis', 'Leishmania guyanensis','Leptomon
+as seymouri','Trypanosoma cruzi','Trypanosoma grayi');
@array2 = ('lin','ldo','lpa','lbr','lgu','lse','tcr','tgr');
@array3 = ('Leishmania infantum JPCM5','Leishmania infantum JPCM5','Le
+ishmania donovani','Leishmania donovani','Leishmania panamensis','Lei
+shmania braziliensis MHOM/BR/75/M2904','Leishmania panamensis','Leish
+mania braziliensis MHOM/BR/75/M2904','Leishmania guyanensis','Leptomo
+nas seymouri','Trypanosoma cruzi marinkellei','Trypanosoma cruzi','Tr
+ypanosoma cruzi strain CL Brener','Trypanosoma rangeli SC58','Trypano
+soma cruzi','Trypanosoma cruzi strain CL Brener','Trypanosoma cruzi D
+m28c','Trypanosoma cruzi','Trypanosoma theileri','Trypanosoma grayi',
+'Trypanosoma grayi');

basically I want to match array3 with array1 and then using the index position of array1, I want to pick the elements from array2.

I have used grep,~~,index, everything, but no success.

I would be great if you can help me.
