How do I create a command to launch a program and then have the terminal wait for a specified time and then move on to the next command?I'm wanting to create a startup script, and I need program B to wait until program A has finished loading up.
View 2 RepliesI'm not quite sure what's up with this, but when I change the title of a terminal away from the default (e.g. to represent which project that terminal is to be used for), it changes back to the default (user@host:path), but only on the task bar at the bottom of the screen, listing the open windows.
If I change tabs in the terminal and then change back, it displays again at the bottom of the screen, but as soon as I execute another command (e.g. ls), then it resets again. That's quite annoying, as I like to have a few terminals open, each with a set of tabs pertaining to a particular project. The fact that I can't see from the title on the taskbar which is which means I have to guess/remember/check them all...
Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
Up until now I've been using plink to remotely compile a project I'm working on. But recently the administrator from the remote server updated the distribution and messed up some configurations. My project has a lot of scripts written for tc shell (tcsh), and now the default shell is bash. There is no way to change this. Another problem is that now I need to run newgrp to change my default user group.
So... to work around this problem I've changed my .bashrc to run newgrp and then tcsh. If I do a normal connection using SSH, everything works as expected, but when using plink, or SSH to remotely execute commands, the shell gets stuck on the newgrp command. I think it's because both applications need a return value from newgrp to send the command I need to execute. Remotely running scripts that call a shell also get stuck like newgrp (newgrp also opens a new shell and that's why it gets stuck) my .bashrc is as follows:
Code:
user_grp=`id -g`
if [ $user_grp != 4919 ]; then
newgrp new_group_id
else

I have a script which builds a project and then runs junit tests. However, if the build fails, the junit tests fail with the same error message.Therefore the command which runs the junit tests should only be executed if the build was successful.
View 3 Replies View RelatedI can't seem to find the Unix command that pauses execution until the user presses a key (i.e. the equivalent of "pause" in DOS). Obviously, I need this for programming. I know about all the performance and security issues of system calls, so please don't recommend I used ncurses or some other library instead. I only plan to use it in small programs that I write to test various algorithms and where perfection isn't needed.
View 3 Replies View RelatedProblem started after installing a new firewall in my network. originally after installing the firewall there would be a 10 second delay after entering a command before it was processed, the command would be executed however there would be an error, i forget what it said, something about not being able to resolve my domain name (and it would give my domain name). i realized this was a problem with my NAT, so i configured DNS forwarding on my firewall so that any attempt to access my server using my domain name from inside the network would point back at my server. after setting up the DNS forwarding i no longer receive the error about my domain name being unreachable, however there is approximately a 30s delay between entering a command and its execution.
the problem is hardly critical i do not see any more serious problems, it is just a pain to do any work when every time i try to do something i have to wait for it to execute.
I have seen command like $rm aa dd cc bb ee then something like $ >> zz // it removes zz also Where aa dd cc bb ee zz are the files in my directory. Do not know exactly.

and I want it to execute via ssh on a remote machine through a script. Therefor I need to escape it properly. Because of the massive use of regular expressions and commandline options, this is not an easy task. Is there any (online) utility that will escape that for bash use? I suppose pasting the code in vi and doing some search and replaces should do the trick. But for that I would need a list of characters to escape...
I have a script:
Quote:
# Call mail script to send an email
if [ -f /tmp/report.txt ]; then
/usr/local/scripts/mail.pl
sleep 10
rm /tmp/report.txt
else
exit
fi
What I need to do is, I want to check if file exists, if file exists call other script (mail.pl) and then delete the file (assuming mail.pl script executed). If file not exists just exit out of the script. I'm not sure how I can see that other script execution completed or not before I delete the file even though I put sleep command. And also it seems like its not that good, even though it is working. I wanted to see if we can write in more efficient way.
I want to use ssh to execute a command and to wait endlessly to log everything (in file) that comes as a stream of the connected server. But unfortunately, in the manual its written "If command is specified, it is executed on the remote host instead of a login shell"
So what happens is that when I specify my command:
ssh user@server "my_command"
It executed the command and the flow of execution returns to bash shell. So basically my session ends right after the command is executed. This happens only in case I specify command in the command line. If I login into ssh manually and then type "my_command", then the session doesn't end. I want the ssh not to exit, because after "my_command" executes, I want to capture everything in the session.
I created a file which in I tried both :
Code:
MAILTO=""

Bottom Line: Dvd Drive died in my toshiba laptop and it was replaced (not before tech for some reason reformatted the Win7 partition... which was 100% un-needed, but thats beside the point now. I redid win7 (the tech installed vista) and am TRYING to "redo grub". Facts: The Slackware AND Ubuntu Partitions ARE STILL THERE and when i use SuperGrub Boot CD (which doesn't restore my grub by itself) to boot into slackware, i can see ALL THE CONTENT of both Linuxes still there including grub on ubuntu partition
(Tri-Boot: Ubuntu, Slackware, and WIn7) I had it working for two years or so, SO i know this "setup" works fine. I am A) Trying to do this as simply as possible. B) Trying to avoid the need to download a 800MB ISO (as seen for this issue on this forum) and trying not to have to reformat Ubuntu Partition (though I have the .Debs I have downloaded for it backed up ... all 1.7GB of them) I have /dev/sda1 as win7, /dev/sda2 as Slack and /dev/sda3 as Ubuntu (which contains Grub Legacy).. Every command I do seems to result in an error like "invalid command" or "invalid Execution format " (i think that second one is right) type errors. I compiled (awhile back) a few kernels for Slackware, but feel goofy that I cant figure what i this out (what i thought was going to be a "2 minute" fix)

I've searched everywhere, but they all talk about BOOTING into the terminal instead of ubuntu.

View 9 Replies View RelatedIn Xubuntu 9.04 I could right click in any directory folder and have the option of opening a terminal window "there". So the terminal command line would open preloaded to that directory. I know, I'm lazy, but it sure made life (and command line work) easier. But it's not available in my new install of Ubuntu 10.04. Now, I know that my gui environment has changed from xfce to gnome, but I would have expected MORE features, not less.
