#### CAT
The cat utility reads files sequentially, writing them to the standard output.
The file operands are processed in command-line order.
Basic usage:
```
$ s3tools cat --help
The cat utility reads files sequentially, writing them to the standard output.
The file operands are processed in command-line order. For example:
s3tools cat bucket-name file1 file2 file3
will print the contents of both file1, file2 and file3 to the standard output.
```
Ex1: Cat all files whose name start with server_log and error_log
```
s3tools cat bucket-test server_log* error_log*
```
Ex2: Cat all files whose name start with log, following by a number
```
s3tools grep bucket-test "log[0-9]"
```
By default, s3tools cat command does not store any file into your local storage.
