Somando números em colunas

Usando paste e bc

 ls -altr | grep "ex.*log" | awk '{ print $5 }' | paste -sd+ | bc
 

A quinta coluna é dos valores do tamanho do arquivo em bytes.

Usando awk

 ls -altr | grep "ex.*log" | awk '{ print $5 } ' | awk ' { SOMA+= $1 } END { print SOMA }'
 

Sem usar grep ainda:

 ls -altr | awk ' /ex.*log/ { SOMA+= $5 } END { print SOMA }'

Usando UNIX find ( exemplos )
