On a Windows XP SP2 system, using a reasonably recent port of GNU sort (and
not the sort.exe that comes in the System32 folder on a windows system), I
am not figuring out how to restrict my sorting fields properly. I've got a
text file where I only want to sort the file based on the first 12
characters of the line (which happens to be a time stamp), and then ignore
the rest of the line. Here is my test input file:
16:58:35.832 DmsSP.exe(3.2.0.30) DmsApp::initConfiguration : {5692}
16:58:35.832 DmsSP.exe(3.2.0.30) DmsApp::initUI : {5692}

There is a tab character between the thousandths of a second and the
filename, and another tab character between the file version and the next
string, except for the line with "ALARM..." on it, where there are two tabs
between the file version and ALARM.
After sorting, it should look like this:
16:58:35.832 DmsSP.exe(3.2.0.30) DmsApp::initConfiguration : {5692}
16:58:35.832 DmsSP.exe(3.2.0.30) DmsApp::initUI : {5692}

The sort command I thought I should use is: sort -k 1,1.12 test.log. Here
is what I get:

Notice the subtle difference: The lines at .957 are not in the same order
as in the original file. Apparently my sort is just sorting the entire
line, instead of limiting the sort determination to the first twelve
characters. What am I doing wrong?
