Ah, I see. Many thanks.
BTW, I see a function that it can add a ssh remote image, like guestfish
-a ssh://[email protected]/path/disk.img, it's really powerful, but why
couldn't I secceed?
#guestfish -a http://slcn03cn15.us.oracle.com/packages/test1.img
http://slcn03cn15.us.oracle.com/packages/test1.img: No such file or
directory

Let's make an example:
#guestfish -a disk.img
run
mount /dev/sda1 /
write-append /a.txt "Hello\n"
write-append /a.txt "World\n"
cat /a.txt
Hello
World
quit
Another try:
eval `guestfish --listen`
guestfish --remote add disk.img
guestfish --remote run
guestfish --remote mount /dev/sda1 /
guestfish --remote write-append /a.txt "Hello\n"
guestfish --remote write-append /a.txt "World\n"
guestfish --remote cat /a.txt
Hello\nWorld\n

libguestfs-1.20.11-11.el6.x86_64
The problem is that \n is handled "specially" by guestfish when it is
reading the ><fs> command line, but not when it is parsing commands
sent via --remote.
The way to do this is:
$ guestfish --remote write /a.txt "hello
world"
$ guestfish --remote cat /a.txt
hello
world
Note that you have to actually press the [Return] key after "hello
Probably a better plan is to use something like python remoting:

which will be more predictable.
