How to select text in BASH terminal using the keyboard without mouse? I'm using Ubuntu 10.10
View 1 Replies View RelatedI just set up apache on my PC and I cant change the permissions by right clicking because "I'm not the owner" and instead of using the chmod command on every file that I would like to edit I would just like to write a script on a text file, save it to my desktop so all I have to do is double click on it and boom I can edit all my files, etc.
View 2 Replies View RelatedI'd like to add custom startup commands (for example starting a process, registering to a registration server, downloading a configuration file) to the Linux startup process. Those commands should be triggered on startup only. What is the standard/appropriate way to do this?
EDIT: Is /etc/profile the right place to trigger such things?
EDIT2: I'm using Ubuntu.
I know it's possible to change the $ user@hostname colors, but is it possible to color different things? Could I make all numbers/integers a certain color. Or set certain keywords to be bold?

I don't want to write login and password, but to press a hotkey (Ctrl + Z for example) to automate this process. [input login, press Enter, input password, press enter, input some command...]
View 2 Replies View RelatedI wonder if it would be possible to create a custom boot menu entry in grub under Ubuntu (11.04), that boots the system into terminal instead of the login screen.
The effect should be something like the root shell in (rescue mode) boot menu entry, one that gives me access to a root shell or a less privileged shell, without the need to select "root shell" explicitly.
If possible, I also would like to customize the shell started by, most preferably by specifying a shell script to run so that I can start something other than bash, like vim.
My intention is to create a "fast" boot mode to give me a usable system within seconds (to take notes, for instance) without needing to start GUI. Therefore, it is preferred that the silent option is turned on.
Note: There is a requirement: that no existing feature of the system is removed. That is to say, the gnome desktop (and Unity) should remain intact, and is only disabled when I choose this mode.
i am on processing text tasks And i found that if you assign a text to a variable is chomp'ed automatically the newline
Code:
variable=$(cat file.txt)
The problem is i can only access the items/lines using:
Code:
for line in $variable
do
echo $line
# Other commands
done
how do i convert this to an indexed array. More importantly, how do i get access to individual $line[0], ..., $line[n] Another thing, if the file.txt, has lines with spaces it is a mess using the for...in..., but echoing prints line by line...o_0
I would like to append text to a file. so i wrote in bashecho text >> file.confHowever it doesnt leave a new line. So i can only do this once. How do i add a new line?

I have a lot a folders, each named by a number, and in each of these folders I have a specific file (stddev.dat) containing a single line (of numbers) I need to have a single file with each line being one of the stddev.dat (no matter if it is sorted or not), and also I need to add at the begining of each line the number of the folder it comes from.
I 'm no bash expert, and the "add at the begining of the line" is a bit of problem to me". Here is what I've come up with so far, just to put everything in one file, (and also if you know a better/more elegant way to do the same thing I've done, I'm listening)

Im used to using nautilus within centos but have recently just got a VPS and quickly realising that using a KDE is unacceptable in this environment. Although I do find it so much quicker doing things like folder permissions in KDE rather than typing it all out in the terminal? Everyone I speak to says, use the terminal and I should learn this way as opposed to using the KDE, but theres certain things I just dont get
How is it possible to make quick changes to scripts and viewing them in a browser etc , without a mouse or using KDE? and only using a terminal?? I am wondering how to develop websites just using the terminal?
How can it be quicker to type out/view permissions etc in the terminal when its instant and just a few clicks in the KDE?
please let me know what are the commands I have to use & how to save a "OpenSuse Terminal text editor" once we have updated the file.

View 5 Replies View RelatedSince I see on my Centos 5 system, when using the Gnome Terminal, there is no 'Find' feature, do I use grep to search the output on Gnome Terminal?
I see grep syntax is:grep search-term file

OS is CentOS 5.5, and GNOME terminal emulator (v2.16.0). However I regard the question is not related with OS/Gnome version level. My question is whether if color setting is available or not for the text character outputted by kernel (or shell, i.e. Bash). Normally we can specify/modify text character color (and background color) with property setting on the terminal. However, it only takes affect to the text for inputting character, not for outputted character by kernel/shell. For example, when we type a shell command "ls -al <cr>", the text appears with the color along with the terminal property.
Meanwhile, the text message displayed on the console (output message against "ls -al" command), in this case it must be file and/or directory names, will appear with some preset color which we've not preliminarily set. In my case, I set Text color with "White", Background color with "Black". Then I expect the text output message color displayed by kernel/shell would be some brighter color. But the color is "blue" which does not look better brightness against "Black" background. For this situation what I'd like to know is how to set/specify the color outputted by the kernel/shell (or whether or not it is possible to set manually).

If I'm in a terminal window, and I open a file by typing eg :
It opens as a blank document... I know it has text in it though!
I've tried with other files and also with nano so it's not just a problem with a particular file.
How do I view the current contents of the file so I can then edit it?
I have a script almost working except for 1 thing. What I'm trying to do is read a file that has the files that need to be FTP'd using a bash script. I have everything working except the reading of the file. It works outside of the ftp script I've wrote but once I put it in the FTP script it doesn't.
Here's the Script:

I've been playing w/ the exclamation points to see if that could be the problem, but so far no luck.
I have a text file that contains a single word and I want to write a bash script that will read the word from the text file... The following is my incorrect attempt, as it assigns the name of the textfile to the variable as opposed to the word stored within the textfile:(assume I have a text file value.txt that has its contents a single word, say wordone)
Code:
#!/bin/sh
for f in value.txt
do
echo $f
done
so the output of the above script is value.txt, however I want it to be wordone.to summarise: how do I assign the value of the word contained within a textfile to a variable?
I want to be able to time how long I spend in front of a terminal. I'm thinking the best way will be to have some sort of timer that starts and stops when the terminal gains/loses focus. And it will have to work with multiple terminals...
I'm using GNOME.
I open up 2 xterms on my desktop, A(/dev/pts/0) and B(/dev/pts/1).I can write from A to B using redirection e.g. echo "test" > /dev/pts/1How do I run a command from A on B? e.g. "clear"Basically I'm putting the 2 terminals side by side, and using terminal B to display the contents of the current working directory, by running the following in A:export PROMPT_COMMAND="ls -a > /dev/pts/1"but this fills up the screen pretty fast. I was actually looking for a way to clear up the second terminal.

PS: i don't have a GUI or X Windows running.

In order to make this conversion I have to use a text editor. This is tedious. Is there an easier way to do it, like some program I can run from the Linux or OSX terminal?
