Sudoer Help....
Hi,
When i use command "sudo -l" under my user, it gives me the following list.
(root) NOPASSWD: /bin/chgrp
(root) NOPASSWD: /bin/chmod
(root) NOPASSWD: /bin/chown
(root) NOPASSWD: /bin/mkdir
(root) NOPASSWD: /bin/su - hubsup
(root) NOPASSWD: /bin/su hubsup
(root) NOPASSWD: /bin/vi *.conf
(root) NOPASSWD: /bin/vi *.xml
(root) NOPASSWD: /usr/bin/find
(root) NOPASSWD: /usr/bin/passwd
(hubsup) NOPASSWD: ALL
Actually I am a bit confused for "/bin/su" command access.
For the lines with "/bin/su" , what does this mean exactly ? Does this mean that, I can do "\sudo su - hubsup" OR "\sudo su -l - hubsup" i.e. switching to hubsup user , which won't ask me for any password.
Actually, I tried with "\sudo su - hubsup" OR "\sudo su -l - hubsup" , from my user account, but, I was not able to switch to "hubsup" user.
with command, "\sudo /bin/su - hubsup" , i am getting blank output on the screen. Pressing enter key, is showing "WinSCP: this is end-of-file:0
" again and again. Then, I need to press ctrl+C to come out of the execution.
Can you please help me, in understanding, what is the meaning of "(root) NOPASSWD: /bin/su - hubsup" and how I can make use of "su" command, from my user-account here. (to switch to "hubsup" user)
Please help.
Thanks and Regards,
Jitendriya Dash.

GZEXE(1) General Commands Manual GZEXE(1)
NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe name ...
DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
penalty in performance). For example if you execute ``gzexe /usr/bin/gdb'' it will create the following two files:
-rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb
-rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~
/usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing executable file. You can remove /usr/bin/gdb~ once you are
sure that /usr/bin/gdb works properly.
This utility is most useful on systems with very small disks.
OPTIONS
-d Decompress the given executables instead of compressing them.
SEE ALSO
gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)
CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the
PATH environment variable to find gzip and some standard utilities (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).
BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases,
using chmod or chown.
