shell - Finding unique values in a data file based on two columns -

-

this question has answer here:

i have file in unix this

name1 text text 123432re text name2 text text 12344qp text name3 text text1 134234ts text name3 text text2 134234ts text

i want find different types of values in 3rd column user names, lets name1, name2 , name3.

like below:

name1 1 name2 1 name3 2

how can required result?

if text in columns before 4th column cannot contain spaces, following should gawk:

gawk '{++vals[$1][$3];}   end {for (u in vals) {        c = 0;        (t in vals[u]) { ++c; };        print u" "c;} }' yourfile

(note, gawk supports multidimensional arrays, while standard awk doesn't, same solution won't work standard awk.)
