Sum a column in a tab-delimited file using Powershell

Assuming you have a bunch of tab delimited files w/out headers and the second column as a number, you could use the following powershell command to sum the values and output the result.

PS > $sum=0; ls | cat | %{ $.split(“`t”)[1] } | %{ $sum+=[int]$ }; $sum

  Sample File:
  
a-count    7
b-count    233
c-count    32
