Here's my linuxquestion I have a bash terminal window opened by next command:
Quote:
gnome-terminal -x bash -c "bash"
Now i need to run different commands or scripts AS ROOT in this terminal window from another terminal. I tried things like
Quote:
sudo echo 123 >/dev/pts/4
The result is 123 in that terminal window, but sudo password is asked in my tab where i entered the command.
If I start a script that is going to take a long time, I inevitably realize it after I've started the script, and wish I had a way of doing some kind of alert once it finishes.
So, for example, if I run:
really_long_script.sh
and press enter...how can I run another command once it finishes?
I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
USAGE="
${0##*/} [-x] [-g]
code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
I am relatively new to linux but i need to run a command in the terminal so i can prevent wireless power save from happening every time i switch to battery power. I dont really want to go into the terminal every time i switch to battery mode so i want to be able to launch this command upon start up:
Code:
sudo iwconfig wlan0 power off

View 9 Replies View RelatedIn windows command prompt, F8 key can cycle through your previously entered commands i.e say you enter "ping google.com" and then "pushd <dir>". Next when you type p and then press F8 brings pushd and next F8 brings ping command. You can then hit enter to execute the corresponding command i.e ping in this case.Is there anything similar in Ubuntu Terminal running bash? Very handy to get back previously entered commands.

View 5 Replies View RelatedI've used the following script here: [URL] to upgrade Alsa to 1.0.21 in Ubuntu 8.04. Now whenever I run:
Code:
sudo shutdown -h <time> or sudo reboot from the terminal I get a rather annoying beep sound. What's even more annoying is if I use the shutdown command to specify a time I get a beep every 10 minutes or so.
I've tried disabling the terminal beep in the terminal profile, disabling the beep in System/Preferences/Sound, adding "blacklist pcspkr" to /etc/modprobe.d/blacklist, and running gconf-editor from the terminal and setting /desktop/gnome/peripherals/keyboard/bell_mode to 'off' rather than 'on'.
When I open a terminal and start the 'top' command to view the running processes, in the summary view I get 4 users. I guess that in addition to my account the root runs in the background but who are the other 2??
View 1 Replies View RelatedRunning debian wheezy. I noticed recently, whenever I fork a process using "&" from a terminal, such as
Code: Select allleafpad &
it starts up, shows the processid in the terminal, but every time when I close the terminal, leafpad gets killed. However, I create a simple bash script,
Code: Select all#!/bin/bash
leafpad&
exit
The script launches leafpad, then exits out leaving leafpad running, as it should. Is what I mentioned above normal? I'm confused, because I think I used to be able to do this in terminal without it depending on the terminal to stay running.
I guess I'm remembering wrong. As it turns out, commands begun on terminal get closed with terminal unless, as mentioned, you use nohup or start subshell. Process hierarchy and tracking etc.
I've created a QT interface with some buttons and labels, and i want to launch a terminal command with one of these buttons,but the command maust starts with "sudo",unfortunately it didn't work because it wants root password and i can't enter it even in the Button cammand....

View 1 Replies View RelatedI 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.
I'm trying to write a bash script program in the Linux command terminal that will write to a fellow user and then continue reading down the program. this is what i have (kind of explains the idea too):
#!/bin/sh

write jcummins
this message should go to jerry
echo "the message didn't send and this string will not appear"
echo "it appears it has stopped at the write command"
I have an executable with input options, like so:
Code:
./executable -n 42 -s 42
I've added gcov to the makefiles (compiling with --coverage, -fprofile-arcs, and -ftest-coverage, and linking with -lgcov). It builds fine and creates executable.gcno.
When I try to run gcov, gcov things the options belong to it:
Code:
$ gcov ./executable -n 42 -s 42
gcov: invalid option -- 's'
Usage: gcov [OPTION]... SOURCEFILE...
When I use quotes this happens:
Code:
$ gcov './executable -n 42 -s 42'
executable -n 42 -s 42.gcno:cannot open graph file
The command line options must remain. How can I get gcov to generate the same .gcno file it later looks for?
I have tried to install Gnome 3 in ubuntu 11.04 and rebooted without installing the gnome-shell. In consequence I see some error messages followed by blank screen after I enter my password in Gnome session, it says failed to load any session. So I have decided to install it by booting to recovery mood to the terminal console by connecting to my existing (working) DSL connection already set up in the Network Manager. Therefore, I need the command how to dial the existing DSL connection via terminal.

View 4 Replies View RelatedI have a home network that includes a couple of computers {A, B, C, D}. currently, I have a cron jon that runs every minute and updates (using rsync) the hard drives of computers {B, C, D} with the contents of hard drive {A}. So far everything works great, as hard drive {A} barely has any information on it. Now, I am about to copy a lot of information (about 8 GBs) to hard drive {A}. Naturally, the cron job will run (as it runs every 1-min) and try to 'sync' the contents with hard drives {B, C, D}.
Given my network (100Mbit/sec), there is no way the cron job will be able to 'copy' the contents to hard drives {B, C, D} in one minute. It will take much more time. Does this situation create a problem? meaning, will cron re-run a new rsync instance 1min later, even though an existing rsync process is running and still copying information to hard drives {B,C,D}? Will my backups be hurt / slowed down tremendously because of this?

i inherited 200 tables in a mysql db from each of the 200 table there are table created on php pages
the information is organized pretty much the same (fields) in each of them, so i dont see the point of having so many different tables
i wanna redesign the db, in 4 tables each of this 200 table have a few essential characteristics, like: table name is (version_country_type), ie: v8_de_pro, v8_de_std, v9_uk_pro the fields are: No, Document_file, Document_path, ISBN, Book_Name, Subtitle, Status, Year_issue, Author
i will need to break the table name, and put each part in the new redesigned 4 tables separate fields...
ill have something like:
id, version, country, type, Document_file, Document_path, ISBN, Book_Name, Subtitle, Status, Year_issue, Author
but i have no idea how to do it i know i cant do it in mysql... so ill need to build up a php script which will need to read every table, and drop it in the new format:
table1 called Main: ID, version
table2 called Cat: ID, IDmain, Country
table3 called Sub: ID, IDmain, IDcat, type
table4 called files: ID, IDmain, IDcat, IDsub, Document_file, Document_path, ISBN, Book_Name, Subtitle, Status, Year_issue, Author
What I would like to do is, with a right click, have the menu give me the option to run srm, which is a "secure remove" program. I picked this one as it requires not only a file name, but some other options. I've run into no support adding things to menus. When I updated one of the Debian versions, I lost the shutdown option from the name menu that used to be there. It was suggested that I right click and pick that option to restore it, but I get the same as the left button on that menu.
