unix - count of columns in file

Question

Given a file with data like this (i.e. stores.dat file)

sid|storeNo|latitude|longitude
2|1|-28.03720000|153.42921670
9|2|-33.85090000|151.03274200
         


        

Answer 1

Perl solution similar to Mat's awk solution:

perl -F'\|' -lane 'print $#F+1; exit' stores.dat

I've tested this on a file with 1000000 columns.

If the field separator is whitespace (one or more spaces or tabs) instead of a pipe:

perl -lane 'print $#F+1; exit' stores.dat
