Counting Columns

[gringomike]

Hi All,

Is there an easy way to count the number of columns from a ps -fu output?

I'm trying to write a script that takes the value of the last column of the ps -fu output but somtimes there are 11 and sometimes there are 12 columns. If there are only 11 columns and my script is hard coded to look for field 12 I could have problems!

I hope this makes sense.

Thanks

GM

In awk the last column is $NF.

Hope This Help, PH.
