How do i run a part of code on exit in a shell script?Suppose i have four echo statements like the following:
echo "Stmt 1"
echo "Stmt 2"
....some code goes here...
[code]...
I have this command in ksh:
1. typeset -i INTEGER INTEGER=aaa In all platforms except of Linux it is failing and return exit code 1 Why in Linux it is not failing? I must it for my number tests
2. The same for printf command. Only in Linux the bellow command is not failing: printf "%d" aaa
Consider the following code:
Code:
...
int ret=0;

I was reading about Ruby code blocks, but it's all a bit hazy.My questions:1. Can you store executable code in the value part of a hash (err...associative array)2. If you did, how would you call the code?3. If you executed this stored code, would it be possible when doing soto pass in an object to the code that it could use?

My rquirement is I have a flat file with lot of lines on it.example:
line1
line2
line3
[code]....
I am trying to create a shell script, on taking a input file as parameter, which need to do 3 things
1) create a copy of existing file.
2) add a new line to the copied file.
3) strip off all the absolute paths inside the copied file
The first 2 points are straight forward. but i am finding it difficult to acheive the 3rd point. myself not very good with awk and sed. but gave it a shot in vain. For example, the input script consists of below,
PROGRAM=`/usr/bin/basename $0`
HOST=`/usr/bin/uname -n`
echo Start $PROGRAM `/usr/bin/date` |
/usr/bin/tee -a $LOG
The output of the script should look like,
PROGRAM=`basename $0`
HOST=`uname -n`
echo Start $PROGRAM `date` |
tee -a $LOG
I am passing an array in function. I want to read the first content again and again until it is empty so
function calltoarray
{
read $1[0]
while [ ! -n "$1[0]" ]
do
echo empty
read $1[0]
done
}
But the code is not working. If we just press enter without value at read $1[0]. It do not get into while loop.
when I execute the command from the shell command line - it works and no error code.if I do the exact same command from a perl file - it fails with code 32512.the file is created from the same perl script that runs the command that fails. file permission is 0664.
Code:
#! /usr/local/pkg/perl-5.8.8/bin/perl
print "Content-type: text/html

I noticed that if I have "exit" in a bash script file., e.g. script.sh,that when the word "exit" is reached, and the script file being executed is not in the PATH nvironment, i.e. ". script.sh", the whole konsole shell profile is exited! What gives here? Is there another command compatible to "exit" to prevent this, or will I just have the leave the "." part in the PATH enviroment, which is, to my understanding, is not recommended? I desire for a "goto" function in bash script files

using 'ntfs-config' to make ntfs partitions mount on bootup so that I can access my data partition from Ubuntu. The first time I installed ntfs-config it would not run. I uninstalled and reinstalled it and then it ran, but it didn't seem to be responding very well. I attempted to tick the partition I wanted and set it to be writeable. After I closed the app ALL my ntfs partitions were mounted, even the windows and system reserved partitions, and when I attempted to unmount them I got the following error:
Unable to unmount Data
Error unmounting: unmount exited with exit code 1:
helper failed with
unmount /dev/mapper/isw_dfjjdefcdi_RAID5p4 is not mounted (according to mtab)
I tried rebooting. I tried uninstalling ntfs-config, then reinstalling it (now it wont run again). So I'm at a loss as to what to do. I simply want my data partition mounted on boot up and writable, not the others.
I learn C++ reading the <C++ primer 4th>, question1.2 let me test if return -1 how the compiler handle this exit code.
and in gcc (GCC) 4.1.1 20070105 (Red Hat 4.1.1-52), I get this show:
[youxi600@Arthas C++ Primer]$ cat q1_2.cpp
int main()
{
return -1;
}
[youxi600@Arthas C++ Primer]$ gcc q1_2.cpp -o q1_2
[youxi600@Arthas C++ Primer]$ ./q1_2
[youxi600@Arthas C++ Primer]$ echo $?
255
[youxi600@Arthas C++ Primer]$
anyone can give me an advise? Many thanks!

View 3 Replies View RelatedAccidentally the usb plug on my WD "My Book" got halfway unplugged and I didn't notice it. when I rebooted it, it wouldn't read the drive. I tried using G Parted to repair it but no success, it just runs forever accessing the drive and never finishes. (I left it running an entire weekend and it didn't finish) the drive is formated ext3.
When I try to mount the drive in Ubuntu 9.10 it gives this error message:
Strangely if I boot into Windows and use the ext driver I can access the drive just fine. is this something I can fix? if needed I can use Windows to do any repairs.
This is a very simple problem, but I'm scratching my head with others..
In composing a simple shell script in class, we can't seem to get the script to execute fully. script was formatted as follows.
#!/bin/bash
echo "good bye for now"
exit
did, Chmod 755 to make executable
type file name "bye"
runs but wont exit.....
it just echos the type"good bye for now
The instructor says it works for him at home....
But it wont work in class...
Is there a reason it wont "exit" the shell as commanded ?

View 1 Replies View RelatedMy two doubts:
(i) In office i open many terminal windows when i start my day and in each terminal i keep on login as different users many times in a day to do some task, by the end of the day when i need to exit from all terminals in a safeway instead of directly closing it i need to execute exit command or CTRL+D many times to close a single terminal safely. Can anybody tell me a way to exit from each terminal in single go, is there any command to acheive this ? I wish if we had a command like exitall like in vi we have :qa command to close multiple files opened in single window. I hope friends you have got what i am asking for ?
(ii) I want a software for debugging shellscripts searched a lot but dint got it.
I write a script to read a file which is something like a pipe (or) queue , which shows the running status.In normal case, if i open this file with cat command, i have to use ctrl+c to exit this . What command shall i use to do the same inside a shell script ? I have tried ^C in my script , but it does not exit the process.
