guestfish如何使用

Guestfish is a shell-like environment for manipulating virtual machine disk images. It allows you to edit disk images, inspect them, and make changes to the file system and data within them.

Here are some basic usage examples of guestfish:

1. Inspect a disk image:

$ guestfish --ro -a disk.img
><fs> run
><fs> list-filesystems
/dev/sda1: ext4

2. Mount a disk image:

$ guestfish --ro -a disk.img
><fs> run
><fs> mount /dev/sda1 /
><fs> ls /

3. Edit files in a disk image:

$ guestfish --rw -a disk.img
><fs> run
><fs> mount /dev/sda1 /
><fs> vi /file.txt

Note: The `--rw` option is used to open the disk image in read-write mode, while the `--ro` option is used to open it in read-only mode. The `-a` option is used to specify the disk image file.

For more information on guestfish and its various options, you can consult the man page by running `man guestfish` in a terminal.
