View 3 Replies View RelatedProgramming :: Communicating From Subshell To Parent Shell
Mar 17, 2010I am stuck at a issue in shell scripting. I had tried all the possible ways, yet unable to reach a solutions. I am working on a application, which runs on C shell. For this I had created a installation script, which installs my application in the system, it is working fine. Now, the problematic part is that I had set an alias in ".cshrc" file, which invokes my application when any user types it. But for an alias to take effect, I need to re-login into the system, because I have to read ".cshrc" file again, in order to take effect of my alias. However I can use "source ~/.cshrc" file after my installation, so that my aliasing works without logging back again. But Requirement is that, just after installing the application, alias should be available to user, without logging back again and without issuing any extra command.
I had tried one other way is that, I had created a symbolic link in ~/bin directory, which points to my application to be run, but even that require, to issue rehash command in order to modify internal command hash table. So, my overall problem is that changing alias in subshell should be reflected to parent shell,without running any other command (all commands should be run in installation script only). Or, in other way how to rehash parent shell from subshell. The ultimate requirement is that,the command that will run my application, should be available just after executing the installation script, either by aliasing or by rehashing, or by any other means.
Programming :: Fork() - Variable Values Between Child And Parent Process?
Feb 24, 2010Code:
int main()
{
int pi;
int i=10;
pid=fork();
[code]....
Q 1. The value of the variable pid returned by the fork() function will be greater than 0 in the parent process and equal to zero in the child process? but during forking, there values are exactly copied so what's went wrong here?
Q 2. "changes to the variable in one process is not reflected in the other process" why it is so? >> Even if we have variable i declared as a pointer or a global it wont make a difference.
Code:
int main()
{
int i, pid;
i=10;
printf("before fork i is %d
[code]....
Q. Through this program it is clear that both process is using the data from the same location, so where's the original value is residing when the child process is in execution.?
Software :: Bash Shell - Export A Variable From A Script?
Jun 24, 2010I need to be able to set a variable that is used by my build environment. I need to be able to change this variable "on the fly" as I work with multiple build environments. A portion of the variable is arbitrary, so I need to treat the arbitrary portion of the variable as an argument.
I would normally just create an alias, but BASH doesn't support arguments to aliases. So the workaround for the no-alias-arguments bug is to use a script. No problem. Except the variable I set in the script does not exist when I exit the script.Now, if I run the script by using "$ . myscript" it works in that the variable is set after it exits. The problem is the argument checking I have in the script doesn't work anymore. BASH aliases don't support arguments and I can't export a variable from a script unless I source the script (is it even a script at that point?) Maybe I am simply taking the wrong approach.

Software :: Video Editing Software That Will Export Back To Mini DV Camcorder ?
May 25, 2011I usually use dvgrab to make an .avi file from the video on our mini dv camcorder and save it to my pocket drive.
Right now I edit this from the pocket drive in Windows 7 on my laptop with Sony's Vegas movie studio HD 9.0 I'm having issues with the laptop lately and with out bogging down in too many details I have to burn the edited video back to the mini DV tape and transfer speeds are causing me problems.
Is there a Linux video editing software that would let me export back to the camcorder? OpenShot doesn't seem to have that option and from what I remember of PiTiVi it doesn't either.
Ubuntu :: Put An Environment Variable Back To Its Default?
Mar 2, 2010I am happy to say that after almost a week of wandering around the INTERNET and posting desperate questions to our Ubuntu forums on how to set paths etc., I have finally begun to understand just how environment variables and path setting works. I must say, it wasn't all reading this or that, but rather making changes to my paths that helped me to understand. Anyway, if anyone who does not understand environment variables is reading this, then I recommend reading this
HTML Code:
http://java.sun.com/docs/books/tutorial/essential/environment/paths.html
and this
HTML Code:
http://www.belugalake.com/java/pathsetting.html
OK- I have 1 last question for my fellow linux users. Lets say I opened up $HOME /.profile and did some editing, and later decided to undo all of my changes but I forgot exactly what changes I made so now I want to set the default in there. How would I accomplish this? How do I set the defaults for any ~/.bashrc or ~/.cshrc type of files that I change.

Sep 8, 2010I want to run some parts of a script in different terminals. I already found about subshell, () using parenthesis to group commands and using xterm -e (function), problem is I cannot get pid for the function running in the other terminal. And if I use & to set the job in background the terminal goes away as soon as it ends the job. I am using log files, and then send it them using built in mail. After all the parts finish I have to run the "main" script which needs the data from all the pieces. Also other question, i usually use bash, but to load a tool i need csh, the tool is not mine so i can not change the csh usage. There is anyway of passing bash scripts/commands at the moment of changing/invoking to csh shell in the same console?

OpenSUSE :: Zip A Folder But Not Include It's Parent Directories?
May 11, 2011I use "zip -r" to zip the following folder:
/root/Desktop/administration/backup
....My only grip is that when you open the zip file, the parent directories are there too.
So within the zip file I have to navigate through "/root/Desktop/administration" just to get to the directory called backup.
Is there a way for me to zip the directory backup, and not include the parent directories? I want to be able to open the zip file and see only the backup directory listed.

OpenSUSE :: Export Remote X To Local Dedicated Virtual Terminal (VT)
Apr 20, 2011I have a "remote" server and I want to have it's X exported to my "local" laptop. Preferably, it gets done automatically from boot. I know that virtual terminals 1-6 are all text terminals and 7 is the local X. How can I get my laptop to automatically create a virtual terminal on 12 that's dedicated to receiving the X display from the server?
I know how to get it over SSH/putty. And also how to stop the local and restart the X client on 7 to use the remote. But one of the beauties of Linux is the automation and multi-user environment. It's essentially going to act as a KVM with gui replacement over IP.

OpenSUSE Network :: NFSv4 Oddity On 4 Servers - Directory Export?
Jan 27, 2011I'm running OpenSuSE 11.3 (64 bit) with the latest kernel update as of yesterday. I've recently moved from NFSv3 to NFSv4 on 4 servers. Between the 4 servers there are 9 exported directories. All of them work except 1 on 1 of the 4 servers.
/etc/exports
# NFSv4 fsid=0 for the top level directory
/export *(rw,fsid=0,async,no_subtree_check,insecure)
# End
# NFSv3
/export/apps/oracle *(rw,async,fsid=7,no_subtree_check,insecure)
/export/ftpserver *(rw,async,fsid=6,no_subtree_check,insecure)
# End
I had to keep the NFSv3 entry as I need that as the mount doesn't work with v4.
/export directory listing
/export:
total 5
drwxr-xr-x 4 root root 104 2002-08-08 16:47 .
drwxr-xr-x 33 root root 944 2011-01-25 17:28 ..

Now on any of the 4 servers if I do:
# mount -t nfs4 machinename:/apps/oracle /mnt
mount.nfs4: mounting lister:/apps/oracle failed, reason given by server:
No such file or directory
But the other sub-dir of /export is fine:
# mount -t nfs4 machinename:/apps/ftpserver /mnt
If I mount the pseudo root:
# mount -t nfs4 machinename:/ /mnt
# ls -l /mnt
total 4
drwxr-xr-x 2 root root 48 2002-08-08 15:20 apps
drwxr-xr-x 8 root root 4096 2010-12-13 12:31 ftpserver
But the apps sub-dir is empty
# ls -l /mnt/apps
total 0
On the server:
# ls -l /export/apps
total 0
drwx------ 3 root root 72 2008-08-06 16:40 etc
drwxr-xr-x 2 root root 240 2011-01-24 03:00 htdig

drwx------ 5 root root 120 2008-08-06 16:40 usr
Well that explains why the NFSv4 mount of /apps/oracle fails because for some reason it can't "see" any files below that, but as I say the ftpserver sub-dir & mount are fine.
