I have this piece of code in my shell script file:
Code:
useradd $UserName; passwd <& $password
I am not able to perform Input Redirection while setting password programatically- without any user intervention.
I think there is a way to do it, but it is just getting slipped from my mind at the moment.
I need user to input a password through command line in Windows cmd prompt. Is there a way to encrypt the input (such as put it into ......) when user is typing ?
View 2 Replies View RelatedI'm creating a bash script to do some tasks for me. I would like the script to be run at a set time of everyday. My first question is if it is possible that if one of the commands in the script requires sudo, is there a way to get around it with out making sudo not require a password. Such as, is there a way to include the password in the script? If that is the case, I can always just set the file as read only by sudo. I've been looking for a way to do this, with no success. if I have a command that wants input, how do I give it to the program. For example, if I want to make a zip file that is encrypted, the command would go as:
Code:
zip -r example * -e
now how would I get the script to insert my wanted password.
I am always confused about the redirection operator <Lets say i have a file input.txt that contains one word "hello" without the quotes when i do the following why don't i see any output? $echo < input.txt Secondly, i am slightly confused between input redirection < and pipe | operator. Sometimes they seem to do the same thing. For example i can achieve the output from the above command as follows $ cat input.txt | xargs echo

Within a bash script, I'm attempting to redirect file descriptors with exec, e.g. exec 3>&1 1>&2; however, I'd like to do something like exec $FD>&1 1>&2, which doesn't work because bash tries to execute the value of $FD. Various placements of eval fail, as well. Is there a way around this, or am I stuck hard-coding the descriptor?

I'm writing a script to execute bash commands in the PHP CLI. I would like to suppress errors from bash and write my own error message if an error occurs. So far I have this (assuming log.txt doesn't exist!):
Code:
tac log.txt 2>/dev/null
Which works as expected, tac kicks up an error but the error is suppressed, but when I use this:
Code:
tac < log.txt 2>/dev/null
I get:
Code:
bash: log.txt: No such file or directory
The tac error is suppressed but bash still gives me a dirty error.
Every time I boot input volume is set to the lowest possible setting... and no-one can hear me.

I use a Logitech USB headset with microphone at work for phone conferencing, and for some reason whenever I restart Ubuntu (and sometimes seemingly at random times), the settings for the audio input device revert to the defaults (the internal audio hardware).I can always reset it back to the USB headset by going to the sound configuration menu (Preferences -> Sound -> Input), but if any applications that use a microphone are already running, they will need to be restarted in order to make use of the newly configured input device.

The asterisk I downloaded came with Centos 5.3 It runs well on VM console But the problem is when It request for localhost login which accepts input but the password does not accept input at all.
since 9.10.My microphone works, BUT only after I open the 'Sound Preferences' panel, and change the setting under the 'Connector' tab to another selection (any will do), then set it back to 'Microphone 1'.Since this works, I wondered if there is a way to make this happen automatically at every login?
View 7 Replies View RelatedI know there is a similar thread but my problem is different from the other one I read.In the other thread, the grub terminal would not accept the password the person would enterIn my case it literally wont let me type my password or anything at all! It asks me to input my password but no matter how many times I press a key nothing happens.Possibly important details: I am following a guide to change the boot order on grub while running the Ubuntu OS and using the terminal. But the issue is the same, I have tried accessing the root mode but it would not let me type my password there either.

I have a Ubuntu 10.10 installed on my HP Mini 210, and is having a problemth authentication dialogs when applications requests for elevated permissions. As far as I concern, there are two types of them, one is the kind when you run anything with gksu where the background dims and a dialog pops up. Another type is when you try toinstall software through Synaptic and a dialog box requests for your password. I am having problems with the later one.
Whenever the authentication dialog box pops up, after typing my password and presses enter, or the Authenticate button, the password field disappears while leaving the authentication dialog on the screen. The Authenticate and Cancel buttons are still clickable, but they are not bringing any actions by clicking them. I would have to let the application to continue with elevated permissions by manually closing the dialog. There are very very rareoccasions where the dialog disappears after I click on authenticate, which I can say is 1 in every 100 times
