[Namba Takaya <takayanamba@xxxxxxxxxxx>]

Dear sir

I have the CTD data (ascii file) below.

How can I read the data in the reverse order using "file" command? 
I want to read the data from the bottom (shallower) to the top(deeper).

depth(m)   temperature       salinity
32.1       29.69             31.8
30.2       29.69             31.8
20.6       29.75             31.5
9.8        29.78             31.2
0.1        29.90             30.7

Thank you in advance.

Takaya Namba
