Ruler

[valkrem]

Hi all,

I am looking for a screen ruler (script) that display  the column position of a variables for a given file.  


Example
Assume I have a file named  "test"  and has three variables

Id     Date      length

123 20150518  2750 
125 20140324  3500

When I invoke  the command -ruler ( or  the script name)  I will see the following

bash$ ruler test
1                        2         3
12345678901234567890
-----------------------------------
123 20150518  2750 
125 20140324  3500

 
Thanks in advance
