### bash compatible syntax

Bash shell syntax is suck though, but calling commands like `command arg1 arg2 ...` is the most convenient way for daily-use. Thus hashell also support some bash builtin syntax.

#### input from file and output to file

syntax
``` bash
# output to file
command args... > ouptut.txt

# input from file
command args... < input.txt
```

#### command pipeline

syntax
``` bash
command1 args... | command2 args...
```

Redirect output of command1 as input of command2. Standard output and standard error should be handled each, which will be supported in future.

### basic functions

#### command history support

Command history is saved in file `${HOME}/.hashell_history.txt`. You can navigate among history by up/down key.

### advanced features

#### auto complete

Auto completion of files and paths is native supported by isocline module
