here,I want output like this way-->> Toronto:Ontario:6:ON
so,I tried using "join" command this way -->> join -t: -j1 5 -j2 2 -o 1.1 2.1 2.2 2.3 file1 file2
which gives me this output,
"join: file 1 is not in sorted order
join: file 2 is not in sorted order

So,i dont understand here why it's giving me only one output line and error that files are not sorted.Do i need to sort the files before joining them?
please help me,I'm a newbie here!

Yes, files need to be sorted on the join field(s).

EDIT: e.g.
bash-3.2$ join -t: -1 5 -2 2 -o 1.1 2.1 2.2 2.3 <(sort -t: -k5 file1) <(sort -t: -k2 file2)
