This is a script that I, this unix forum and stackoverflow come up with. I would like to get some feedback about it and improve it little bit if possible for even more readability and better working. OR get some shaming hilarious opinion.
Quote:
What this script does?
It checks whether this Script is ran with Bash shell.
If it did not, the notice will be echo'ed.
And the Script rerun with Bash.
Later:
It will check whether this Script is ran by the User that can execute Sudo directly or will be promped for a password.
The notice will be echo'ed.
Little bit more Later:
It will check if the User that executes this Script ran the Script with Sudo.
If Not, this script will be re-run with Sudo and Bash.
Code:
#!/bin/bash
currentShell=$(readlink /proc/$$/exe);
if [ "$currentShell" != "/bin/bash" ]
then
echo 'The script is ran by different shell, not Bash shell, be cautious next time.';
echo 'I will rerun this script with Bash shell for You, to avoid unusual behaviour';
exec bash "$0" "$@";
fi
declare sudoPasswordCache=$((sudo -n true) 2>&1);
if [ "$sudoPasswordCache" = "sudo: a password is required" ];
then
echo ""
echo 'This script is required to be ran as root user.';
echo 'You will be asked for a password';
#else echo 'You have a cached password in place, no need for password.'
fi
if [ "$EUID" -ne 0 ];
then
exec sudo bash "$0" "$@";
echo "exec failed" >&2
exit 1;
fi
I want develop a script which should also check validity of netmask.
e.g.
/etc/netmasks
10.15.20.30 255.255.255.224
How can I check which IP adresses are valid for this netmask?
I think the best is use logical operations.
224 is 1 1 1 0 0 0 0 0
so is valid from 10.15.20.31... (2 Replies)

NAME
installsieve - user utility for managing sieve scripts
SYNOPSIS
installsieve
DESCRIPTION
installsieve is a utility that allows users to manage their sieve scripts kept on the server.
OPTIONS -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.
-l List all of the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
script.
-p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.
-i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten. Upon sucessfully
putting the script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
sieve names may not contain a '.'.
-a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..
-d <name> Delete the sieve script on the server with <name>.
-m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.
-g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already exists it is
overwritten.
-u <user> Userid/Authname to use for authentication; by default, the current user.
