equivalent to su or sudo?

equivalent to su or sudo?

[Ulli Horlacher]

I need to run some scripts with full administrator rights (for chown,
chmod, setfacl).
Is there a cygwin equivalent to su or sudo?

None of these answers work for me.
For example "cygstart --action=runas id" pops up a windows for
milliseconds without any chance to read it.

If by that you mean "run privileged program inside a user terminal", no.
This is inherently insecure and not supported under Windows.

Whatever runs these scripts must already have aquired administrative
rights.

No, you can only start out with administrative rights and then drop them
when no longer needed (cygdrop --help).

I use the following shell script to start a command as Administrator. I mainly just use it to start mintty.

#!/bin/bash
cmd="$(cygpath -da "$1")"; shift
if [ $# -gt 0 ]; then
  powershell Start-Process "$cmd" -ArgumentList \""$@"\" -Verb RunAs -WindowStyle Hidden
else
  powershell Start-Process "$cmd" -Verb RunAs -WindowStyle Hidden
fi

You don't need powershell for that.

<file name="/usr/local/bin/runas">
#!/bin/sh
export PS1="% "
cygstart --action=runas mintty --title=Admin -e /bin/bash -il
</file>

The export of PS1 is to mark that the terminal window is in
administrative rights.  You can modify the shell program to dash, ash
zsh or whatever you favorite shell is.  Make sure to issue the
interactive and login support for the shell.

I've actually found that after installing and configuring sshd as a
service, "ssh localhost" gives me an elevated shell without any hassle
(I'm part of the local admins group; you may have to modify to "ssh
admin@localhost").  If you want to use this as a replacement for
'sudo' without having ssh open to the network, modify your sshd
configuration to only accept localhost connections and as an added
layer, make sure your firewall denies all incoming network traffic to
sshd
