Programming :: How To Turn Non-interactive Shell Into Interactive Shell?

Feb 4, 2011

I have a situation where I am in a non-interactive shell. I have tried from within my non-interative shell to spawn an interactive shell but my output still does not goto me. Isn't there a way I can somehow go into /proc or somwhere and make the output my /dev/tty1? Or some way else to remedy this?The situation arises because I drop from my restricted shell environment (a sort of CLI interface), into the actual Linux shell. I cannot change the code of the CLI environment I am just faced with being in the linux shell environment and its non-interactive. Its very annoying to have to put > /dev/tty1 after every command I type.

Not to mention it seems damn near impossible to get pagers like more and less to work properly when your in a non-interactive shell.

Programming :: Testing Interactive Shell $- $PS1

Mar 22, 2010

I'm writing a bash script that can be run by crontab or by a user interactively.

If the script is run by a user interactively, it will ask for a parameter interactively.

If the script is run by the crontab, it validates if a command line parameter is provided.

In doing so, I cannot get these tests to work inside the bash script


This shell is not interactive

How the tests be done inside a script?

Programming :: BASH Shell Differences: Login Or Interactive

Feb 18, 2011

Intuitively I think that the Login Shell and the Interactive Shell are the same applications but have access to different environmental variables.It this true? Why is there more than one type of shell anyways? You can change users with the interactive shell, why not log on with it to?

Programming :: Combining Commands And Var's In Bash Shell Script?

Jan 5, 2011

I have a command which on the command line needs to look like this

rlam -if3 '!pvalue -H image1.jpg' > image2.jpg

Nevermind what rlam or pvalue do ... they are part of a program package I am using. The above command works on the command line, and also when written verbatim in a bash shell script.

My problem is: in the script I wish to replace image1.jpg with the content of a variable, e.g.


How to I get the script to insert the value of $IM into the command when the pvalue part of it needs to be quoted?

Programming :: Invoking UNIX Shell Commands From HTML Webpage

May 11, 2010

I have a few questions regarding HTML, UNIX and Javascript. I've been tasked with creating a fairly simple webpage that takes a few inputs. Each input must correspond to an argument in a UNIX command running on a server.On a UNIX server we have a script (.ksh) that takes 3 arguments. The result of the script is a data file which is FTP'ed to an external server. Let's forget about the FTP portion for now. I would like to know where I should begin.What I know so far:

1) I will need HTML to create the webpage. Skill level is high
2) I will need Javascript to make my webpage more interactive. Skill level is high.
3) I will need to understand the UNIX environment. Skill level is high.

Debian Multimedia :: Skype Starting Every Time When Open Interactive Root Shell

Jan 20, 2015

I recently "upgraded" to the latest skype and now every time I open an interactive root shell, up pops skype. I can close skype then control-C in the terminal window to get the shell I want, but this is annoying to say the least. Maybe my google-foo is off, but all I can find is articles on how to run skype as root, which is no use. I've tried searching the startup files for "skype" (case independant), but so far all I can find is "LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu/ /usr/bin/skype" in the root .bashrc which shouldn't be starting the app.

what could be causing this?

Programming :: Script Wich Will Act As And Interactive Front End To An Emailer?

Apr 6, 2009

Code:-ask the user which files they want to sent (files not needed to be in the same directore-tar all the files together-Gzip the tarfile-Uuencode the gsipped file (so more email programs can use it)-ask user who to send email to, possibly more than one person-I want it to be clear and easy to use and display what it is doing while an action is taken place.I have no clue where to begin. I think perl would be the best option, but I am not sure, how would I make this able to run with am email program and I am unaware how to tar and gzip files or Uuencode the gsipped files.

Software :: Interactive Ruby Shell - Irb - Have Ruby But No Irb?

Oct 22, 2010

There are a few things not working properly. Ruby version manager seems ok but untill i get working with ruby i don't know if it is working properly. One thing that is not there is irb Interactive ruby is not available according the the message i get.

Well i have no idea what readline is but i did everything that is on that webpage referance page [url]. I have got a lot of progress and learned heaps about linux shell and bash terminal. The thing is i need to get this going and have tried feenode but it is very foreign and how it works i do not have a clue. I have got 2 things resolved so far through this forum but using other threads in it. i need to get irb going before i can progress to using ruby on Rails properly.

I am using a Eeepc running ubuntu easy peasy its version 9.04 of ubuntu. I need the whole of rails to work and want to get a handle on using ruby version manager along with the apache stack with mysql/phpmyadmin and am using this as a dummy run for setting up a development system.

Programming :: Launching Interactive Gnome-terminal With A Command (and Not Exiting)

Oct 13, 2010

I want to have a script (tcsh/bash/python) that launches a bunch of gnome-terminals (or 1 with multiple tabs). And I want it to execute a command, but keep the shell interactive. Currently, if you type gnome-terminal then it launches a new interactive shell, but if you give it the execute flag, then it executes the command and quits (or stays open, but non-interactive depending on the users gnome-terminal settings).

I have this command which I want to run automatically before I start working. What the command does is dynamic and different for each shell. It takes arguments. So it's not something I can take care of in a .cshrc type file.

Debian :: Run GUI Commands From Shell?

May 22, 2011

The panel plugin from xfce4-mixer has a bug:s icon doesn't update as the volume is changed. This bug has already been reported.One curious thing about it is that, if you right click on the volume icon on the panel, go to 'Settings' (or 'Properties', I don't know, mine is in Portuguese) and then close the window that pops on the screen, the icon is updated.Is it possible to open and close the settings window automatically with a bash script? Like this, I could associate this script with the volume keys of my keyboard, so that the icon is updated as the the volume is changed.

General :: What Shell Allows Recalling Commands With Certain Beginning

Sep 14, 2011

Programs like matlab/octave and I'm sure many other ones allow you to start typing a command, and then hit Up to recall the last command that starts with the typed characters. Common linux shell bash doesnot do this. Is there a different shell that does? I'm not asking how to find out the last command, I'm asking if there's a shell that's a little friendlier.

I want to copy a file (home/remote_computer_user/Desktop/test1.txt) from my remote office computer (a permanent URL + open port) to my home computer (home/home_computer_user/Downloads/).

(I think I should use scp, but I dont how exactly how in my case)

What are the exact commands I should use?

I.e log a command of "ls *.log" as just that, rather than "ls a.log b.log c.log d.log" It makes rather a mess of the log files.

General :: Configure Using Arrow Key To Repeat Previous Shell Commands In Minix?

Jul 20, 2011

I am new to Minix. I'm so impressed by the speed of the system. It looks elegant, I like it. However, I have a question about the shell. In Linux, while using a shell, up and down arrow keys can be used to navigate through previously executed commands. On Minix with the sh shell, I can only get numbers printed out on the screen. I remember I chose a US-std keyboard when installing. Is there any way to use the arrow keys to navigate through previous commands on Minix?
