filter a content file to table

Question

this is the input I have generated , that displays the versions of courses for both Jany and Marco at different times .

Answer 1

With GNU awk for true multi-dimensional arrays and sorted_in:

$ cat tst.awk
BEGIN{ RS=""; FS="[[:space:]:]+" }
{
    for (i=11; i<=NF; i+=3) {
        sched[$7" "$8][$2":"$3][$i] = $(i+1)
        courses[$i]
    }
}
END {
    PROCINFO["sorted_in"] = "@ind_str_asc"
    for (name in sched) {
        printf "%s", name
        for (time in sched[name]) {
            printf ",%s", time
        }
        print ""
        for (course in courses) {
            printf "%s", course
            for (time in sched[name]) {
                printf ",%s", sched[name][time][course]
            }
            print ""
        }
        print ""
    }
}

.

$ gawk -f tst.awk file
Marco 1,10:00,14:00
applicaton,halfhour,onehours
theory,geo,programmation

Marco 2,10:00,14:00
applicaton,nothing,nothing
theory,history,philosophy

jany 1,10:00,14:00
applicaton,onehour,twohours
theory,nothing,nothing

jany 2,10:00,14:00
applicaton,twohour,twohours
theory,math,music

It doesn't exactly produce your posted expected output but I think that's because your posted expected output is wrong (e.g. check the output for jany 1 application 14:00 compared to your input - the input is twohours like my script produces but you say the expected output is halfhour).
