.. / vigr

This command allows to edit some designated files (/etc/passwd, /etc/group, /etc/shadow and /etc/gshadow) safely by spawning the default editor (falling back to [vim](/gtfobins/vim/), other functions may apply). Despite requiring superuser privileges to run, the editor is executed as the unprivileged user when run as SUID or with sudo.

suid

suid是一种授予文件的权限类型，它允许用户使用者以文件所有者的权限来执行文件。

```
./vigr
```

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 vigr
```
