Running shell script fragments via guestfish "command"

[Charles Duffy]

What's the Right Way to do the below?
> <fs> command "bash -c 'for D in avahi-daemon avahi-dnsconfd haldaemon;

do /sbin/chkconfig $D off; done; true'"
libguestfs: error: D: -c: line 0: unexpected EOF while looking for 
matching `''
D: -c: line 1: syntax error: unexpected end of file

The problem is that guestfish's list splitting code sucks, so
the above turns into the equivalent of this API call:

guestfs_command (g, "bash", "-c", "'for", "D", "in",
    	"avahi-daemon", "avahi-dnsconfd", "haldaemon;",
    	"do", "/sbin/chkconfig", "$D", "off;", "done;", "true'");

Please file a bug about this.

In the meantime you can write what you really wanted to write using a
language binding such as Perl.  Or if you need to use guestfish then
write a small shell script to do the operations you need and use the
'upload' and 'chmod' commands to upload it, chmod it and run it inside
the guest.
