Uma maneira de fazer isso no awk seria:
Código:
$ awk '{ for (i=4; i <= NF; i++) print $1, $2, $3, $i }' file1
file1:
10000001 ABC $5.00 ABC01 ABC001 ABC1
10000002 BCD $2.34 BCD01 BCD.go BD.c.2 BDDCD7
Resultados:
10000001 ABC $5.00 ABC01
10000001 ABC $5.00 ABC001
10000001 ABC $5.00 ABC1
10000002 BCD $2.34 BCD01
10000002 BCD $2.34 BCD.go
10000002 BCD $2.34 BD.c.2
10000002 BCD $2.34 BDDCD7
