I would like to reorder a whole file by ascending time order.
file.txt looks like this:
a 12.24 text
a 1.45 text
b 5.12 text
i would like it to look like this
a 1.45 text
b 5.12 text
a 12.24 text
Thanks in advance
A:
Use the sort linux programme, not awk. Precisely:
sort -n -k 2 <filename>

To clarify, the difference between -n and -g is explained here: http://stackoverflow.com/questions/1255782/whats-the-difference-between-general-numeric-sort-and-numeric-sort-options-i .

A:
The sort command may fit your needs better than awk.
# sort -gk 2 test.txt
a 1.45 text
b 5.12 text
a 12.24 text
-g compares them as numbers instead of strings. And -k 2 sorts on the second column.
