I used to use ls -l cut to detrmine file size, and google searches didn't come up with anything else but 'stat' which doesn't appear on HPUX.
I discovered the humble 'wc -c' which does this job very neatly, and thought I would share it. (7 Replies)

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.

ls(1) General Commands Manual ls(1)
Name
ls - list and generate statistics for files
Syntax
ls [ options ] name ...
Description
For each directory argument, lists the contents of the directory. For each file argument, repeats the file name and gives any other infor-
mation you request with the options available. By default, the list is sorted alphabetically. When no argument is given, the current
directory is listed. When several arguments are given, files are listed first, followed by directories and the files within each direc-
tory. Options are listed below.
Options
-1 Displays one entry per line. This is the default when output is not to a terminal.
-a Displays all entries including those beginning with a period (.).
-C Forces multicolumn output for pipe or filter. This is the default when the output is to a terminal.
-c Uses time of last file status change (ctime), reflecting file creation, mode, etc., for sorting (with the -t option) or printing (with
the -l option) rather than the time of file modification or access. See also the -t and -u options.
-d Displays names of directories only, not contents. Use this option with -l to get the status of a directory.
-F Marks directories with trailing slash (/), sockets with a trailing equal sign (=), symbolic links with a trailing at sign (@), and
executable files with a trailing asterisk (*).
-f Displays names in the order they exist in directory. For further information, see Entries beginning with a period (.) are also
listed. This option overrides the -l, -t, -s, and -r options.
-g Displays assigned group ID (used with -l only). Default is assigned owner ID.
-i Displays the i-number for each file in the first column of the report.
-L Lists the information, if the file is a symbolic link, for the file or directory the link references rather than that for the link
itself.
-l Lists the mode, number of links, owner, size in bytes, and time of last modification (mtime) for each file. If the file is a special
file, the size field contains the major and minor device numbers instead of the size. If the file is a symbolic link, the pathname of
the linked-to file is printed, preceded by ``->''.
The mode field consists of 11 characters. The first character indicates the type of entry:
d if the entry is a directory
b if the entry is a block-type special file
c if the entry is a character-type special file
l if the entry is a symbolic link
s if the entry is a socket
- if the entry is a plain file
The next 9 characters are interpreted as three sets of three characters each. The first set of three characters refers to file-access
permissions for the user; the next set, for the user-group; and the last set, for all others. The permissions are indicated as fol-
lows:
r if the file is readable
w if the file is writable
x if the file is executable
- if the indicated permission is not granted.
The group-execute permission character is given as s if the file has the set-group-id bit set; likewise, the user-execute permission
character is given as s if the file has the set-user-id bit set.
The last character of the mode (normally `x' or `-') is t if the 1000 bit of the mode is on. See for the meaning of this mode.
-q Forces the printing of nongraphic characters in file names as the question mark character (?). This is the default when output is to
a terminal.
-R Recursively lists all subdirectories.
-r Sorts entries in reverse alphabetic or time order.
-s Displays the size in kilobytes of each file. This is the first item listed in each entry.
-t Sorts by time modified (most recently modified first) instead of by name. See also the -c and -u options.
-u Uses the time of last access (atime) instead of last modification for sorting (with the -t option) or printing (with the -l option).
Restrictions
The output device is assumed to be 80 columns wide.
New line and tab are considered printing characters in file names.
The option setting based on whether the output is a teletype is undesirable as "ls -s" is much different than "ls -s |lpr". On the other
hand, not doing this setting would make old shell scripts which used ls almost certain to fail.
Files
Used to obtain user id's for ls -l
Used to obtain group id's for ls -g
