If you want to calculate the size of all files owned by “patrice”, you can use awk. The following script does that for you:
$ ls -lk /tmp | awk '/^-/ && $3=="patrice" { total +=$5 } END { print total "k" }' |
How does it work? Every column of the ls command is stored in a variable. The variable is a dollar sign followed by the number of the column. The first line of the awk script matches all lines starting with a dash (this are files) and where the third column is equal to “patrice”. As the third column contains the owner name this gets all files owned by patrice. The block inside the curly braces gets executed for each match. This code sums up the size of this file to a total.
