Libguestfs - Jun 2019 - Re: Guestfish command - "copy-out" not working for symbolic links

Hi Nikolay,

We use guestfish, so I preferred to use commands supported by guestfish.
I tried as below but "realpath" is not working after I have the target
path from symlink.
--> Check if the path has a symlink.
is-symlink path
Ex. - is-symlink "/etc/resolv.conf"   -> return true

--> If it's true then get target link path
readlink path
ex. - readlink "/etc/resolv.conf"  --> return
"../run/systemd/resolve/stub-resolv.conf"

--> Which return's target path but it's not a full path, so needs to
get full path to access the target file.
Tried to use realpath as below using target path from above return but it's
giving None

ex. - realpath "../run/systemd/resolve/stub-resolv.conf"  -->
return None


Can you tell me how can I get the real path as without the full canonicalized
absolute path I can't do anything with that file.


Thanks,
Chintan

If it is one time operation you can call 'realpath'
(http://libguestfs.org/guestfs.3.html#guestfs_realpath) first to
resolve symlink.

This no going to work.
AS I told you I need something under guestfish command list not from guestfs
commands.

Thanks,
Chintan

Chintan,

Use 'download' (http://libguestfs.org/guestfs.3.html#guestfs_download)
