Top Forums UNIX for Dummies Questions & Answers Determining file size for a list of files with paths Post 302555439 by Corona688 on Wednesday 14th of September 2011 06:04:03 PM

That's a useless use of cat. Use file redirection instead to save CPU time and avoid the unintended side-effects of having an extra pipe in the way.

-0 only works if the file's separated by NULLs. I'm guessing yours is separated by newlines.

Since you have -0 though, you're probably using the GNU utilities, which makes things simpler:

Code:
<filename xargs -d '\n' du -b --apparent-size -c | tail -n 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. SEE ALSO
