As I wrote in the code first comment, this script must take two arguments, a pathname <path> and a directory <dir>, then it has to select every regular file with .c extension in <path> and to copy it in <dir>. You have understood correctly.

Here's the files I use:

Code:
luke@luke-desktop:~/Desktop/TEST$ ls
folder1 folder2
luke@luke-desktop:~/Desktop/TEST$ cd folder1
luke@luke-desktop:~/Desktop/TEST/folder1$ cat hello1.c
while
while
if
luke@luke-desktop:~/Desktop/TEST/folder1$ cat hello2.c
luke@luke-desktop:~/Desktop/TEST/folder1$

Here's the code when I run it, using ./folder1/ as <path> and ./folder2/ as <dir>:

Code:
luke@luke-desktop:~/Desktop/TEST$ bash -x es3 ./folder1/  ./folder2/
 + '[' 2 -eq 2 -a -d ./folder2/ ']'
 ++ grep '\.c$'
 ++ ls ./folder1/
 + for file in '$(ls "$1" | grep "\.c$")'
 + '[' -f hello1.c ']'
 + for file in '$(ls "$1" | grep "\.c$")'
 + '[' -f hello2.c ']'
 + exit 0

It is clear that

Code:
if [ -f "$file" ]

is always false, and if I comment it, then

Code:
if [ "$a" -gt 1 -a "$b" -gt 1 ]

is always false.

And I don't understand why, maybe some syntax errors?

PUPPET-RESOURCE(8)						   Puppet manual						PUPPET-RESOURCE(8)

NAME
puppet-resource - The resource abstraction layer shell SYNOPSIS
Uses the Puppet RAL to directly interact with the system. USAGE
puppet resource [-h|--help] [-d|--debug] [-v|--verbose] [-e|--edit] [-H|--host host] [-p|--param parameter] [-t|--types] type [name] [attribute=value ...] DESCRIPTION
This command provides simple facilities for converting current system state into Puppet code, along with some ability to modify the current state using Puppet's RAL. By default, you must at least provide a type to list, in which case puppet resource will tell you everything it knows about all resources of that type. You can optionally specify an instance name, and puppet resource will only describe that single instance. If given a type, a name, and a series of attribute=value pairs, puppet resource will modify the state of the specified resource. Alter- nately, if given a type, a name, and the '--edit' flag, puppet resource will write its output to a file, open that file in an editor, and then apply the saved file as a Puppet transaction. OPTIONS
Note that any configuration parameter that's valid in the configuration file is also a valid long argument. For example, 'ssldir' is a valid configuration parameter, so you can specify '--ssldir directory' as an argument. See the configuration file documentation at http://docs.puppetlabs.com/references/stable/configuration.html for the full list of acceptable parameters. A commented list of all configuration options can also be generated by running puppet with '--genconfig'. --debug Enable full debugging. --edit Write the results of the query to a file, open the file in an editor, and read the file back in as an executable Puppet manifest. --host When specified, connect to the resource server on the named host and retrieve the list of resouces of the type specified. --help Print this help message. --param Add more parameters to be outputted from queries. --types List all available types. --verbose Print extra information. EXAMPLE
This example uses puppet resource to return a Puppet configuration for the user luke: $ puppet resource user luke user { 'luke': home => '/home/luke', uid => '100', ensure => 'present', comment => 'Luke Kanies,,,', gid => '1000', shell => '/bin/bash', groups => ['sysadmin','audio','video','puppet'] } AUTHOR
