gawk asort to sort record groups based on one subfield
input ("/" delimited fields):
Code:
style1/book1 (author_C)/editor1/2000
style1/book2 (author_A)/editor2/2004
style1/book3 (author_B)/editor3/2001
style2/book8 (author_B)/editor4/2010
style2/book5 (author_A)/editor2/1998

Records with same field 1 belong to the same group.
Using asort (not sort), in each group I need to sort the records in ascending order based on the string between braces in field 2, to obtain:
Code:
style1/book2 (author_A)/editor2/2004
style1/book3 (author_B)/editor3/2001
style1/book1 (author_C)/editor1/2000
style2/book5 (author_A)/editor2/1998
style2/book8 (author_B)/editor4/2010

I tried to sort the records by field1 and then by subfield2 in field2, but it didn't work:
Code:
BEGIN{FS=OFS="/"}

{
    array[$1] = $0

    split ($2, aut, " ")

    asort(array)

    o = asort(aut)

    for (o in aut)
        print array[aut[o]]

}
