# dcat
Implementation **cat** unix tools using pure **C programming language**. (Just a draft tool for Donya OS)
## Features
- Tiny code
- Good performance
- Support most features of unix `cat` tool
- Concatenation some files to one output
- Read from **STDIN**
- Depends on glibc
## Help
```
Usage: dcat [OPTION]... [FILE]...
Concatenate FILE(s) to standard output.
With no FILE, or when FILE is -, read standard input.
-l, --learn learn and read offline documentation
-A, --show-all equivalent to -vET
-b, --number-nonblank number nonempty output lines, overrides -n
-e equivalent to -vE
-E, --show-ends display $ at end of each line
-n, --number number all output lines
-s, --squeeze-blank suppress repeated empty output lines
-t equivalent to -vT
-T, --show-tabs display TAB characters as ^I
-u (ignored)
-v, --show-nonprinting use ^ and M- notation, except for LFD and TAB
--help display this help and exit
--version output version information and exit
Examples:
dcat f - g Output f's contents, then standard input, then g's contents.
dcat Copy standard input to standard output.
