permisi agan2 master komputer, ane mau tanya dikit, kira2 ane punya teks seperti ini:

This is the first line

This is the second line

This is the third line

This is the fourth line

terus mau ane rubah jadi:

BEFORE This is the first line

BEFORE This is the second line

BEFORE This is the third line

BEFORE This is the fourth line

terus ane rubah lagi

BEFORE This is the first line AFTER

BEFORE This is the second line AFTER

BEFORE This is the third line AFTER

BEFORE This is the fourth line AFTER

Kira2 buatnya gemana ya? ada yg punya referensi make ms.word atau libre office atau notepad++ ataupun gedit?
konteksnya ane punya teks ratusan line, ya kalo ada jalan pintasnya ga perlu paste line by line 1 1.

terima kasih sebelumnya master komputer
