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?
The other day I was practicing some of the famous Awk One-liners and noticed something interesting in the bash shell on ubuntu 9.04. Some specific awk commands would execute correctly but when I tried to use an up arrow to re-run the command that particular command was not present in my history. Is this an issue specific to me? specific to awk? Completely random?
need to modify some scripts to repeat the commands in them until a variable returns a proper value. I need it to add some redundancy to some scripts i use to upload files to a remote server.This is an example of a portion of those scripts:
Is it possible to use the keyboard in order to select some text in the terminal windows that is not in the currently edited line? (for example, in order to copy part of previous command output).
My previous experience with Ubuntu desktop (which isn't much) while in the terminal the up key allowed me to see previously entered commands, but I have freshly installed Ubuntu Server Edition and the up key is not allowing me to do so, Is there a way to get this working?
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/).
How can I do this with shell commands in Linux?
My current thoughts:
ssh <user>@<computer1address> -p <port> - gives me a shell on the remote computer (I think I should use scp, but I dont how exactly how in my case)
i have RHEL4. i m facing problem that all the previous command history is deleted when i restart the server or relogin the server. it is happening with all the users not with any one user.
I want to write an operating system of my own ! I've started studying Minix. For getting started I wanted to know is there a way to write and add a background process [printing 'hello'] in the Minix operating system ?
I am trying to write a script that connects to a server and executes some commands on there. Something like this:
#!/bin/sh telnet remote_machine cd /home/some_directory cat a_file_in_current_directory
Unfortunately after login/password I guess the script doesn't jump past the telnet command, until I exit. What do I need to do to make the script start executing commands in the remote shell?
i was trying to figure out a way to write my own linux commands.. in fact i wanted to write a shell script to simulate an already existed linux commands like 'cd','ls' and'adduser'i just dont know the language of scriptting and even doesnt know the steps to make a script
I'm trying to boot Emdebian Grip 1.0 built on Compact Flash on a mini PC with grub2 as bootloader. Unfortunately , the booting is unsuccessful and I got stuck into an error message :Code:No filesystem could mount root , tried : minix msdos iso9660kernel panic - not syncing : VFS : Unable to mount root fs on unknown-block (22,1)It seems grub2 hasn't tried to mount ext2 as the filesystem and my Compact flash is formatted as ext2. Here is the menuentry of the grub.cfg :
Code: menuentry "Debian GNU/Linux, linux 2.66.2.9-custom" { insmod ext2
I need to process billions of small files using bash shell commands with limited memory size (256MB). If any of those files contain certain "keywords", the file will be removed. I tried with command:
Totem can play .flv file download on Internet. However it can't repeat playing. At end of playing the .flv file following warning popup, disregarding [Repeat Mode] check or uncheck
Code: An error occurred internal data stream error [OK]
After clicking [OK] and the starting icon [triangle] I can replay .flv file.
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.
I have a .wav file (a drum beat) that I want to use to play along with. The problem I am encountering is that I can't get either VLC or Windows Media Player (both on Windows 7) to play the file in repeat mode gaplessly, which makes it useless since it's a drum beat and it needs to be precise.
Is there some program on either Windows 7 or linux that you know can do this?
Is anyone familiar with the Minix OS? i want to know what is the Process to add a new command in Minix that uses system call served by the memory manager server
i need to run a command from a shell script that requires me to answer "Yes" to 2 questions that the command asks before it kicks off. how do i do this? i thought it was something like this.. from inside the parent script:
How can I run the following be run from a shell script, these are shell commands and mysql commands.

In below program I want to add (as part of the valid_cmds string) the pwd (print working directory), lo (logout), and cd (change directory) commands.

Ok, so I have a few web apps that need to run shell commands. Heres a great example of one:
Code:
This is a PHP script getting my system volume. Herein lies the problem... www-data doesn't have permission to do this!
I changed my apache config to use MY account as the web user, and it does in fact work the way I want it to.
Obviously, I dont want to leave apache running as me, and want it to keep using www-data.... heres my question... how can I give permission for www-data to execute certain programs?
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.
IM1=image1.jpg
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?
php. I am developing a web-interface for an application that sometimes needs root privs. Editting /etc/sudoers is not an option since the web interface needs to be portable to other users when they install my application. Is there any workaround ?PHP Code:
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.
