How to check that file exists on AppVm from dom0 bash script?
Or simple get the exit code of the remote process?

no need to echo $?, the exit code is passed to dom0 too. Eg.:
# qvm-run --pass-io $appvm "test -e /bin/ls"
# echo $?
0
# qvm-run --pass-io $appvm "test -e /bin/blah"
# echo $?
1
status=$(qvm-run --pass-io $appvm "cat $file" > dom0file
If $file is not exists how to get notify about it on bash script?
if ! $(qvm-run --pass-io $appvm "test -e $file"); then
your_commands_here; fi
but you'll also catch qvm-run errors (eg. $appvm not running). A
workaround would be to choose a custom exit value, like so:
qvm-run --pass-io $appvm "test -e $file || exit 199"
if [ $? -eq 199 ]; then
your_commands_here
fi
thanks
