How can i create a new bash session with a user from the current bash session,
I know i can do it with only one command
tryin to figure it out.
$ su <user> -c bash
replace the username desired. You will either need to know the password of the user or run it as root.
or, you could do any of the following
$ screen -S <user>
$ bash --login <user>
All of which will accomplish your task
Reference Linux screen command: http://linux.die.net/man/1/screen
You can create a new session in your bash by this:
screen -S test

i would like to know how can I get the path to sources.list on a modified UNIX which have apt and other base packages on it , like gpg and sudo. Does apt can identify the path to sources.list ?
He is using it , so he should be able to locate it, right ?
I don't know if this is the best way, but apt-config dump will show all of apt's configuration variables. On my system, the Dir::Etc variable gives the directory where the file is located, and Dir::Etc::sourcelist gives its name.
You can also read in the apt-config man page about the shell option which may be more useful for processing this data in a program.

I want to find all the files a piece of software has left in my system.
In the terminal I type:
$ find /Users -name software -print
And every time find tries to look into a folder within the Library directory, Terminal returns "operation not permitted".
So I tried:
$ sudo find /Users -name software -print
Same result
So I finally enabled super user, logged in with command su, entered my command: same result.
1 - I do not understand why even the super user is not allowed to search the library.
2 - what is the work around?
Thanks for your help
I have found the answer.
Terminal needs to be added in the System Preferences/Security and Privacy/ full disk access!

I'm running rsync underneath Supervisor. I normally start rsync daemon like this:
rsync --daemon --config=/home/zs6ftad/deployments/cmot_rsync_daemon/rsyncd.conf --no-detach
I'd like to make it so that any log messages get echo'd to standard output instead of being stored in the log-file. Is there an option which will make an rsync server behave this way?
You can get rsyncd to log to stdout by setting the --log-file argument to /dev/stdout
rsync --daemon --no-detach --log-file=/dev/stdout

I am trying to edit a file in vi editor - and when I try to save the changes it says READ ONLY. Even when I try to do a chmod I get an error saying I cannot do so.
I have logged in Unix using a personal ID and not a service one
Because you aren't owner of this file. You need to sudo vim with an owner user.
Try opening editing the file in vim using: sudo vim <filename>
Some people also recommend adding this to your .vimrc file so you can open the file without sudo then write to it anyway using :w!!
" Sudo to write
cnoremap w!! w !sudo tee % >/dev/null

We need to password protect the activities on the crontab, for ex even if we try
crontab -l
or
crontab -e
or
crontab -r
We would have to enter a password to go to the next level(viewing/editing/deleting) even if we are root user.
Kindly suggest some mechanisms.
Thanks.
If you don't trust the root user on your system I would say you have big problems. I don't think there is any way to securely protect anything from root - by definition this user can do what they like, including removing any protection you put in place to try to enfore a password when executing crontab.
