Root user/sudo equivalent in Cygwin?

I\'m trying to run a bash script in Cygwin.

I get Must run as root, i.e. sudo ./scriptname errors.

chmod 777 scriptname does no

What I usually do is have a registry "Open Here" helper in order to open a cygwin shell with administrative privileges quite easy from anywhere in my computer.

Be aware you have to have the cygwin "chere" package installed, use "chere -i -m" from an elevated cygwin shell first.

Assuming your cygwin installation is in C:\cygwin...

Here's the registry code:

Windows Registry Editor Version 5.00

[-HKEY_CLASSES_ROOT\Directory\shell\cygwin_bash]

[HKEY_CLASSES_ROOT\Directory\shell\cygwin_bash]
@="Open Cygwin Here as Root"
"HasLUAShield"=""

[HKEY_CLASSES_ROOT\Directory\shell\cygwin_bash\command]
@="c:\\cygwin\\bin\\mintty.exe -i /Cygwin-Terminal.ico -e /bin/xhere /bin/bash.exe"

[-HKEY_CLASSES_ROOT\Directory\Background\shell\cygwin_bash]

[HKEY_CLASSES_ROOT\Directory\Background\shell\cygwin_bash]
@="Open Cygwin Here as Root"
"HasLUAShield"=""

[HKEY_CLASSES_ROOT\Directory\Background\shell\cygwin_bash\command]
@="c:\\cygwin\\bin\\mintty.exe -i /Cygwin-Terminal.ico -e /bin/xhere /bin/bash.exe"

[-HKEY_CLASSES_ROOT\Drive\shell\cygwin_bash]

[HKEY_CLASSES_ROOT\Drive\shell\cygwin_bash]
@="Open Cygwin Here as Root"
"HasLUAShield"=""

[HKEY_CLASSES_ROOT\Drive\shell\cygwin_bash\command]
@="c:\\cygwin\\bin\\mintty.exe -i /Cygwin-Terminal.ico -e /bin/xhere /bin/bash.exe"

Hope this helps. Let me know if it works for you. Thanks.

PS: You can grab this code, copy and paste it and save it in a name.reg file to run it... or you can manually add the values.
