sorting stuff

andi_1 — Mon, 06 May 2002 19:45:38 GMT

Hi,

I have an arbitrary input in the following form:
c0t11d2 NONE 4095 JBOD/Other SEAGATE
c0t8d1 NONE 4095 JBOD/Other SEAGATE
c0t9d0 NONE 4095 JBOD/Other SEAGATE

I need to perform sort on device field (dX).
I am thinking of using

sort -k 1.LengthOfTheDevice (e.g. sort -k 1.6) filename

Since, the disk name is of variable length, how can I ensure that I always search based on D value?

Thank you!

sort -t 'd' -n -k2,2

Sorry, I might have been not clear enough. I have another requirement:
Suppose, the following info I have:
c0t0d0 NONE 4095 JBOD/Other SEAGATE
c0t0d1 NONE 4095 JBOD/Other SEAGATE
c1t0d0 NONE 4095 JBOD/Other SEAGATE
c1t1d1 NONE 4095 JBOD/Other SEAGATE

When I sort by d, I also need to make sure that the following output displayed:

c0t0d0
c1t0d0
c0t0d1
c1t1d1

If I were to use the sort like this:
sort -t 'd' -n -k1,6 diskDBt

I'd get the following output:
c0t0d0
c0d0t1
c1t0d0
c1t1d1

Thank you!

If we use 'd' as the field separator, then we need sort by the second field - correct?
If so, then try using -k2 instead of -k1,6

The suggested solution is very close. If you want to sort by the 'd' portion as the most significant and then then stuff that precedes it using 'd' as a field separator this should work:

sort -t 'd' -k 2,2n -k1,1b infile
