I have multiple vhosts on a host running apache. It is a test system and I would like to give users "basic authentication" access to their sites.

For this I have a vhost file with basic auth configuration:

<VirtualHost *:80>
    ServerName demo.com
    ServerAlias test.demo.com
    DocumentRoot /filepath/to/demo.com/public_html
    <Location />
        Deny from all
        AuthUserFile /filepath/to/demo.com-users
        AuthName authorization
        AuthType Basic
        Satisfy Any
        require valid-user
    </Location>
</VirtualHost>

This works fine and can be done per virtual host domain.

Question: For the staff I would like to set a global "auth directive" in the normal httpd.conf file that allows them to login to all vhosts in one step.

Can this be done and how?

How exactly do you have to interpret the output of a commands "usage" output, in bash for example.

For example, on my OS X, cp gives me

usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file target_file
       cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file ... target_directory

• What does the nested options, like -H within -R, indicate?
• Does upper and lower case have any meaning?
• When is an argument optional, required?

I need to implement a telnet command line against a program of mine and I would like to get this straight.

I am playing with CouchDB and whenever I do, I first have to issue

sudo couchdb -i -u couchdb couchdb -b

This starts CouchDB as the user couchdb, group couchdb. I then also have to enter my password again (I am admin but still need to, when doing a sudo) and all is fine.

How do I run CouchDB or anything similar at startup? Anytime anyone logs in, without any user interaction in OS X?

In Java it is possible to create a random UUID:

UUID uuid = UUID.randomUUID();

How to do this in Bash?

Sometimes I forget how the exact syntax of a CMD command looks and then I would like to search my own CMD history. Clearly, within the same session, you can browse it with the up and down arrow keys but what about the history of former CMD sessions? Is there a file, a log the history gets written to or does it all go to digital Nirvana?

Thanks!

I am auto creating scheduled tasks with this line within a batch windows script:

schtasks /Create /RU SYSTEM /RP SYSTEM /TN startup-task-%%i /TR %SPEEDWAY_DIR%\%TARGET_DIR%%%i\%STARTUPFILE% /SC HOURLY /MO 1 /ST 17:%%i1:00

I wanted to avoid using specific user credentials and thus decided to use SYSTEM.

Now, when checking in the taskmanagers process list or, even better, directly with the

C:\> schtasks

command itself, all is working well, the tasks are running as intended.

However in this particular case I would like to have an open console window where I can see the log flying by.

I know I could use

C:\> tail -f thelogfile.log

if I installed e.g. cygwin (on all machines) or some proprietary tools like Baretail on Windows. But since I only switch to these machines in case of trouble, I would prefer to start the scheduled task in such a way that every user immediately sees the log.

Any chance?

Thanks!

I want to start a long running process from a windows batch file. The start script should just call the second script and return, end. How can I achieve this?

Thanks!

I have a loop in a batch script and I would like to do some arithmetics with the loop counter. I found out how to evaluate expressions, how to add numbers here: Evaluating expressions in windows batch script

How do I do the same but with variables?

For example:

set x = 100
for /L %%i in (1,1,5) do (
    set Result=0
    set /a Result = %%i+%%x
    echo %Result%
)

As output I would expect

101 102 103 104 105

Thanks!

This one could turn out as the dumbest question ever, as I am probably missing out the obvious. Anyway, here it is: Can you evaluate expressions in a batch script. For example, I want to add two numbers and print the result:

echo 4+2

This will just print "4+2", not "6". Maybe I am taking batch scripting on windows a little bit too far...

Thanks!

I need access to the current time from within a batch script. When typing time in the cmd, I get something like this:

The current time is: 16:58:03.98
Enter the new time:

What I need is not that but the hour, the minutes and the seconds in seperate buckets that I can then process in any arbitrary way. In other words I am looking for a function that returns the value for the hour so that I can assign it to a variable, like so:

var hour = GetCurrentHour()

Thanks!

I want to dynamically setup scheduled tasks in windows.

So far I have a bat script that deploys some software in various places. The next step would be to start/stop those programs at certain intervals through scheduled tasks. Hence they have to run a certain script every hour or so...

Thanks!

I need to run a windows command n times within a bat script file. I know how to do this in various programming languages but cannot manage to get it right on the windows command line :-(

I would expect something like either

for(int i = 0; i < 100; i++) {
   // do something
}

or even this (though not entirely seriously)

1.upto(100, {
   // do something
}) 

Thanks!

EDIT

I can write a program in java, perl, c or whatever that will generate a bat script that looks like this

for %%N in (1 2 3 4 5 6 7 8 9 10 11 12) do echo %%N

and so on. Or even "better":

echo 1
echo 2
echo 3
echo 4
echo 5
echo 6
echo 7
echo 8
echo 9
echo 10
echo 11
echo 12

and then execute it... But the thing is that I need a concise way to specify a range of numbers to iterate through within the script.

Thanks!

I need to copy a full directory tree (aka recursive copy) with a bat files on windows. On *nix systems I use the -R argument on the copy command, like so:

cp -R fromDir toDir

and that did the job. I could not find anything similar in the windows "man pages" of the copy command.

Thanks!

Excuse my newbie question but I haven't had to touch bat scripts since the days of the autoexec.bat... and that one was even called from the system directly.

So I wonder how I can pass in arguments to my bat script?

For example I want to create n directories with a certain name. I would like to use a construct such as this one:

for %%N in (1 to $arg1$) do mkdir $arg2$-%%N

As a result I would like to have N directories called

• name-1
• name-2
• name-3

... and so on.

Thanks!

I have many bat files that share a common setup of variables. Instead of defining the same variables over and over again (and making errors in the process) I would like to include one bat file in all the others.

How do I do this? Excuse my newbie question but the last time I touched bat, it was a file called autoexec.bat, long ago...

Thanks!
