Full Discussion: Piping results of 'ls' to 'find' using 'xargs'
Operating Systems Solaris Piping results of 'ls' to 'find' using 'xargs' Post 302346131 by MartynAbbott on Friday 21st of August 2009 05:46:32 AM

Piping results of 'ls' to 'find' using 'xargs'
I'm trying to get a count of all the files in a series of directories on a per directory basis. Directory structure is like (but with many more files):

/dir1/subdir1/file1.txt
/dir1/subdir1/file2.txt
/dir1/subdir2/file1.txt
/dir1/subdir2/file2.txt
/dir2/subdir1/file1.txt
/dir2/subdir2/file1.txt

So, I want my output to be something like:

dir1
4
dir2
2

To achieve this I tried:

ls -d1 dir* | xargs -n 1 find {} -type f | wc -l

but I get the following error message:

find: bad option dir1
find: path-list predicate-list
...

It appears that find is interpreting the directory passed by xargs as an option rather than a path-list.

Can anyone explain why please?

Thanks for taking the time to look.

NAME

       dircmp - directory comparison

SYNOPSIS

       dircmp [-ds] [-w n] dir1 dir2

DESCRIPTION

       The  dircmp  command  examines dir1 and dir2 and generates various tabulated information about the contents of the directories. Listings of
       files that are unique to each directory are generated for all the options. If no option is entered, a list is output indicating whether the
       file names common to both directories have the same contents.

OPTIONS

       The following options are supported:

       -d	Compares  the  contents  of files with the same name in both directories and output a list telling what must be changed in the two
		files to bring them into agreement. The list format is described in diff(1).

       -s	Suppresses messages about identical files.

       -w n	Changes the width of the output line to n characters. The default width is  72.

OPERANDS

       The following operands are supported:

       dir1	A path name of a directory to be compared.
       dir2

USAGE

       See largefile(5) for the description of the behavior of dircmp when encountering files greater than or equal to 2 Gbyte ( 2**31bytes).

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect the execution of dircmp: LC_COLLATE,	LC_CTYPE,  LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred. (Differences in directory contents are not considered errors.)

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
