gksu kdesu, tdesu, ktsuss

Stuff that has not yet gone into the official build.

gksu kdesu, tdesu, ktsuss

What are the correct paths to all of these? Or maybe just use $(which blah) and not worry about the path.

Here's a sample wrapper script for refractasnapshot-gui that should eliminate the dependency on gksu or other graphical frontend to su/sudo.
Code: Select all
#!/usr/bin/env bash
# Wrapper for refractasnapshot-gui


# I hope nobody uses this, but it's here
# in case you're running a root xsession.
if [[ $(id -u) -eq 0 ]] ; then
   exit 0

# This will be used to test for sudo nopasswd.
sudo_allowed=$(sudo -n uptime 2>&1 | grep load | wc -l)

if [[ -e /usr/bin/gksu ]] ; then
   gksu "$command"
   [[ -e /usr/bin/kdesu ]] ; then
   kdesu "$command"
   [[ -e /usr/bin/kdesudo ]] ; then
   kdesudo "$command"
   #another way to do it
   [[ -e $(which tdesu) ]] ; then
   tdesu "$command"
   [[ -e $(which ktsuss) ]] ; then
   ktsuss "$command"
   # for xudo with no password
   [[ $sudo_allowed -ne 0 ]] ; then
      sudo "$command"
   # for sudo with password
   $(groups $USER | grep -qs sudo); then
   xterm -fa mono -fs 12 -hold -e  "sudo $command"
   xterm -fa mono -fs 12 -hold -e su -c "$command"

exit 0

I've typed this to check (not in the context of a script, though) then press enter to exit without changes
Code: Select all
sudo update-alternatives --config gksu

$(which blah) should generally be fine but opt/trinity/bin/tdesu might not show up (at least for root) in $PATH .. use the full path. Not sure about kdesu http://forums.debian.net/viewtopic.php?f=16&t=40158

Need to review the licence for ktsuss, it's similar to but not actually GPL. I posted a (monster 33 KB) deb: http://exegnulinux.net/refracta/experim ... 1_i386.deb

I would really prefer a more "generic" (non-DE-specific) method which does not alienate users with limited cli skills. X for root (e.g.yad), as mentioned earlier, is likely to be an issue.

I may just go with xterm. When I ran snapshot from the menu and didn't get a terminal, I missed it. Most of the time, I run the gui script from command line, because I'm using a different config file, so that the config file that goes into the iso is the default, instead of with all my changes. (filename, compression, save_work, and maybe something else.) And I like being able to see that progress bar for mksquashfs. It lets me know roughly how many other things I can do before it's finished.

And if the wrapper script can't guess correctly whether the user uses su, sudo with password or sudo without password, there can be an error message that says "Run this with root privs, however you get them."
