Determining file size for a list of files with paths
Hello,

I have a flat file with a list of files with the path to the file and I am attempting to calculate the filesize for each one; however xargs isn't playing nicely and I am sure there is probably a better way of doing this.

What I envisioned is this:
Code:
cat filename|xargs -i ls -l {} |awk '{total = total + $5}END{print total}'

but xargs -i and xargs -0 do not seem to work, so is there a way of doing this without xargs? The list of path/to/files has spaces between some of the paths so that is why regular xargs is not an option.

Thanks in advance!

systemd-path

SYSTEMD-PATH(1) 						   systemd-path 						   SYSTEMD-PATH(1)

NAME

       systemd-path - List and query system and user paths

SYNOPSIS

       systemd-path [OPTIONS...] [NAME...]

DESCRIPTION

       systemd-path may be used to query system and user paths. The tool makes many of the paths described in file-hierarchy(7) available for
       querying.

       When invoked without arguments, a list of known paths and their current values is shown. When at least one argument is passed, the path
       with this name is queried and its value shown. The variables whose name begins with "search-" do not refer to individual paths, but instead
       to a list of colon-separated search paths, in their order of precedence.

OPTIONS

       The following options are understood:

       --suffix=
	   The printed paths are suffixed by the specified string.

       -h, --help
	   Print a short help text and exit.

       --version
	   Print a short version string and exit.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
