openssh unix dev - Mar 2005 - command reordering

ssh myname at myhost 'printf %s: `hostname` ; ssh -V && printf %s:
`hostname` ; php -v'

Will return something like:

myhost:myhost:OpenSSH_3.5etcetcetc
4.x.y


Why is ssh putting the printf's together?  This also works with any
combination of ;/&& vs echo -n/printf.

I found this site talking about rsync and getopt problems, but I
haven't figured out the work-around yet:

It doesn't - you have just overlooked that ssh -V sends its output
to stderr, while printf and php -v send it to stdout. Changing
your command line to

ssh myname at myhost 'printf %s: `hostname` ; ssh -V 2>&1 &&
printf %s: `hostname` ; php -v'

should work. (Assuming something sh-compatible as your login
shell, won't work that way with csh.)


Ciao
