1 2 Admin Script



If you want to be paranoid, you can put set -o errexit in your script. This means the script will fail and stop if one command returned a non-zero exit code, which is the unix standard way to signal that something went wrong.




1 2 Admin Script



As an admin, I'm always wanting to log the output of some command, often not a script. To solve that problem, I've written a few things. The easiest is to use the program "script" as xX0v0Xx mentioned. I found that calling script (without any arguments) would often result in me overwriting the output of a previous script. So I created this alias. All it does is prevent overwriting. You need a /tmp directory.


So, here is an option I used and consider to be a little more friendly. Essentially, define a task function at the top of your script, and define all of your sections with their own functions to be passed to calls of the task function. It could be extended to add some specific INFO, WARN, DEBUG, and ERROR flags for your logs as well. They would simply be functions that use an echo to wrap your message in a consistent way, as all of the outputs are going to your log anyway.


I understand that the call don't pass to admin script, what I meant was when the call hit on the IF statement node in the main script, it should check Global.userCurrentState value which could be either 1 , 2 or 0.


The access levels are assigned to users in one or more security tables loaded within the Section Access part of the script. These tables must contain, as a minimum, two system fields: ACCESS, which is the field defining the access level, and USERID or USER.EMAIL . Other optional system fields can be added depending on the use case. The full set of Section Access system fields is described below.


Restrict access to row-level data by adding a data reduction column to the security table in the access section of the load script. Specific records (rows) can be hidden from users by linking the Section Access data with the real data. The selection of data to be shown or excluded is controlled by having one or more reduction fields with common names in Section Access and Section Application parts of the script. After user login, Qlik Sense matches the selections in reduction fields in the access section to any fields in the application section with exactly the same field names (the field names must be written in uppercase). After the selections have been made, Qlik Sense permanently hides all data excluded by these selections from the user. If a wildcard (*) is used as a field value in the data reduction column, it is interpreted as allowing the user to access records associated with all selected reduction fields in the security table.


Restrict access to column-level data by adding the OMIT system field to the security table in the Section Access script. The following example builds on the previous example where row data reduction is already in place.


I am looking to write a script that takes user input, then makes system wide changes. I need this to be very generic, but simply put, at the top, I need it to check to see if it's being run 'As an Administrator'. If it's not, then I want to display a message to tell them that; if it is, I want it to continue on. Is there a constant way to verify this? I am not looking to start a new session as the Administrator, I just want to detect if it's currently run as admin


The code works in Win2k+1, both with and without UAC, domain, transitive groups, whatever - because it uses the same way as the system itself when it's checking permissions. chkadmin prints "Admin" or "Non-admin" and sets the exit code to 0 or 1, respectively. The output can be suppressed with the /q switch.


It might surprise the saltiest of system administrators to know that there is no Linux cron command. The cron daemon (crond) is a system-managed executable that runs in memory with which users may schedule tasks. The user command to work with the cron service is crontab (cron table). The crontab file is a simple text file that instructs the cron daemon to perform a task at a certain time or interval. Any user may schedule cron tasks or jobs on a system. The task runs under the user account from which it was created. In other words, if you create a cron task, it runs with your user account's permissions. The same is true for any user on the system, including the root user.


As you can see from the image, the positioning of your entries has meaning, and the entries are separated by spaces. An asterisk (*) means every or all, as in every minute or all hours, every day, and so on. In other words, the image currently illustrates a crontab entry for a script that will run every minute of every day. This practice, while rare, does exist in some instances. However, for most cron tasks, you will need to be more specific.


For the following examples, assume that you have a script, backup.sh, that you want to schedule on your system. You've placed all your system scripts in /etc/scripts, which is a directory that only root has access to.


As you can see, cron scheduling is easy once you understand the syntax. The only real stumbling blocks you might experience with cron are pathing, permissions, and timing. You have to think about how long a script requires to execute and produce output before scheduling another process that depends on it. Referring back to the dmesg script, you can see that you need to know how long the dmesg command requires to finish processing and writing to the dmesg.txt file before scheduling the next command, which is to email the dmesg.txt file to yourself.


Typically, the way system administrators and other users automate processes on a Linux system is to create scripts that perform functions such as creating files, moving files, emailing information, performing backups, reporting on backups, etc. When you schedule those same scripts in cron, you've created true automation on your system. There are very few repetitive tasks that cannot be automated using cron and scripts. If you experience problems with automating tasks that require passwords or interactive sessions, use expect scripts to automate those. If you don't know expect, watch Enable Sysadmin for future posts on the topic.

Scripts can be stored in the Script repository or can be written directly to the console. The events used to trigger script execution include, but are not limited to the System Scheduler, the Traffic Monitoring Tool, and the Netwatch Tool generated events.


Variables can be used only in certain regions of the script called scopes. These regions determine the visibility of the variable. There are two types of scopes - global and local. A variable declared within a block is accessible only within that block and blocks enclosed by it, and only after the point of declaration.


Note: Starting from v6.2 there can be undefined variables. When a variable is undefined, the parser will try to look for variables set, for example, by DHCP lease-script or Hotspot on-login


If a variable is initially defined without value then the variable data type is set to nil, otherwise, a data type is determined automatically by the scripting engine. Sometimes conversion from one data type to another is required. It can be achieved using data conversion commands. Example:


You can also invoke the services script via distribution-specific service management commands. Distribution packages often provide a similar script, sometimes as an init script, to manage services. Refer to your distribution-specific service management system for more information.

Paths with spaces need to be enclosed in quotation marks.It is important to specify a working directory the user you are running as has access to, otherwise the function will fail.It is recommended that you only load the user's profile if you are sure you need it. There is a small chance a profile can be stuck in memory under the right conditions. If a script using RunAs() happens to be running as the SYSTEM account (for example, if the script is running as a service) and the user's profile is loaded, then you must take care that the script remains running until the child process closes.When running as an administrator, the Secondary Logon (RunAs()) service must be enabled or this function will fail. This does not apply when running as the SYSTEM account.After running the requested program the script continues. To pause execution of the script until the spawned program has finished use the RunAsWait() function instead.Providing the Standard I/O parameter with the proper values permits interaction with the child process through the StderrRead(), StdinWrite() and StdoutRead() functions. Combine the flag values (or use $STDERR_CHILD, $STDIN_CHILD & $STDOUT_CHILD) to manage more than one stream.In order for the streams to close, the following conditions must be met:1) The child process has closed its end of the stream (this happens when the child closes).2) AutoIt must read any captured streams until there is no more data.3) If STDIN is provided for the child, StdinWrite() must be called to close the stream. Once all streams are detected as no longer needed, all internal resources will automatically be freed.StdioClose() can be used to force the STDIO streams closed.The "load profile" and "network credentials only" options are incompatible. Using both will produce undefined results.There is an issue in the Windows XP generation of Windows which prevents STDIO redirection and the show flag from working. See Microsoft Knowledge Base article KB818858 for more information about which versions are affected as well as a hotfix for the issue. Users running Windows XP SP2 or later, or Windows Vista or later are not affected. 041b061a72
