Sort by 2nd field

Here's a sample of what I have in a log file:

p1-OST001e oss031
p1-OST001f oss032
p1-OST0020 oss033
p1-OST0021 oss034 
p1-OST0022 oss035
p1-OST0023 oss036
p1-OST0024 oss037
p1-OST0025 oss038
p1-OST0026 oss039
p1-OST0027 oss040
p1-OST0028 oss031

I want to sort it so the 2 OSTs match up with the oss ie.

p1-OST001e oss031
p1-OST0028 oss031
p1-OST001f oss032
etc

would be together.

You can use:

$ sort -t' ' -nk2.4 file
p1-OST001e oss031
p1-OST0028 oss031
p1-OST001f oss032
p1-OST0020 oss033
p1-OST0021 oss034 
p1-OST0022 oss035
p1-OST0023 oss036
p1-OST0024 oss037
p1-OST0025 oss038
p1-OST0026 oss039
p1-OST0027 oss040
  • -t' ' sets space as field separator
  • -n sets numeric sort
  • -k2.4 sets column 2 to be the index to sort by. With .4 we indicate to sort from the 4th character.
