Programming :: Argument Relations In CGI Script
Feb 15, 2010
I have made fallowing script for CGI scripting learning purpose:
Code:
#!/bin/sh
echo "Content-type: text/html"
echo
CMD='echo "$QUERY_STRING" | sed -n 's/^.*cmd=([^&]*).*$/1/p' | sed "s/%20/ /g" '
echo "<html>"
echo "<head><title>Hello CGI</title></head>"
echo "<body>" .....
echo "<input type=radio name=cmd value=ifconfig checked> ifconfig <br>"
echo "<input type=radio name=cmd value=uname> uname -a <br>"
This script works fine, but actually I quite don't understand it's inner working about those radio buttons.

I'm trying to write a base script which will divide an argument by 10 and then use that argument in another program. Since my argument can be a floating point number, I used bc to accomplish this. Here's an example of a simplified version of what I have so far:
<code>NUM=$(echo "scale=25;$1/10" | bc)
#make sure the first argument was formatted correctly
if [ $? -ne 0 ]

I need to write a script that will take 1 command line argument. The argument will be a username. The script will determine if the user exists on the system and will print an error if it does not. If the user does exist it will determine if the user is currently logged in, if the user is not logged in it will determine the last time the user logged in and display the file in the users home directory that was most recently modified.

I am trying to simulate a shell. So what I do is checking of having the parameters from standard input, suc as "/bin/ls -l /home/france/Documents", and then passing them to function execute, which at some point calls execvp(argv[0],argv)The problem is that I don't succeed in using these arguments, while if I call execvp(paramList[0],paramList) it works!!!! Where paramList is exactly what I would put on standard input, but defined statically.
Code:
#include<unistd.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
[code].....

I'd like to pass the following arguments to a bash script in any order:
Code:
myscript -l <country> -r <file1> <file2> ... -o
I read the argument list in a switch shift loop. I figured out how to read the filelist but only if -f is the last option.
how to position the file list anywhere in the argument list?

Write a program that requires the user to input the name of a file as an argument. If the user fails to include one argument it should make use of a thread that handles a signal. The signal handler should tells the user Incorrect number of arguments and then calls the terminate signal on the process.
If the numbers of arguments are correct then the program should allocate memory space to the file (5MB) and create a child process that requests the user for a character that it should send to the parent. The child should keep request for data until the user keys in the character O. During each request it should pause for 10 seconds, send the character to the parent and then requesting again for another character.
The parent should get the character from the child. Do not make the parent wait for the child to finish requesting for data. Make use of pipes to facilitate communication between the parent and the child. A second child should be created to read and display data from the file. Make use of any appropriate Inter Process Communication technique to ensure that the second child and the parent do not access the file simultaneously (Mutual exclusion).

am coding a chat program in C (win32), where I need both the client and the server to communicate, without waiting for a reply from the other side, like the way we chat in any messenger. Is there any way of accomplishing it? I tried out CreateProcess() function, but am not clear how to specify the location of the file as an argument.If there are better techniques than CreateProcess(), then

Feel free to just link to another thread where this is (pre)solved; I can't search the forum for the word "for," because it's too short (or maybe the search engine dislikes prepositions).
Is there a way to give the 'for' command a range? Here's what I mean:
Code:
#for i in (1-5); do echo $i; done
Certainly, meat space user; I understand exactly what you're thinking.
1
2
3

True, I realize I could use
Code:
COUNT=1 ; while [ $COUNT -lt 6 ]...
...but if I can avoid the extra preparatory step I'd prefer to do so.

I am attempting to script some tasks I have to do, but I have no control over one of the scripts I have to use... and they output all kinds of useless things on the screen. My goal is simple: Capture all output from their scripts, and create a progress line that only shows the most recent output from their stuff. So, here was my first solution; a file I called "spin":
Code:
#!/bin/bash
spinX(){
PROC=$1
STRT='date "+%s"'
while [ -d /proc/$PROC ];do
last3=" 'getLine $2' "
To use it, you pass it a process ID and a file that contains the output from that process. As the process continues, a kurby dances on the screen (To let you know that the process has not hanged), and the tail of the output is shown (To let you know what it is doing). When the process ends, the kurby stops dancing and the time it took is displayed.
And here is the file I call "noise":
Code:
#!/bin/bash
while [ i -lt 100 ];do
i=1
echo "Look at me count!$"
sleep 1
let "i=$i+1"
done
This does nothing but create random output, for testing. It counts from 1 to 99 on the screen. To run my test, I do the following:
Code:
(noise) &>tmp.txt & spin $! tmp.txt
It works relatively well, but it is messy. I don't like creating a temp file, and I don't like the messy syntax for calling my program. I decided that I would rather move everything into the spin program, to make using it less messy:
Code:
#Spin Psuedo code
#$1 = command I am about to run
(exec $1) &>tmp.txt & spinX $! tmp.txt
By executing the process inside of the spin code, I can get rid of the tmp file later on without changing a lot of scripts (Or move it, or whatever). I can also call it by passing the command to the script, which I find more elegant.
So here is what I would like to know:
1) If possible, I would love to get rid of the tmp file all together, and store the most recent line of output from script 1 into a variable that script 2 can print out instead... is it possible?
2) How can I run a random command that is passed as an argument? Basic ones work fine, but anything with a pipe fails me.
Example of a script:
Code:
#!/bin/bash
#myEcho.sh
echo;echo "Recieved command: ";echo $1;echo;
echo "Attempting to run command: ";echo
exec $1
Example code for passing commands to script:
> myEcho.sh "ls -al" #works
> myEcho.sh 'ls -al' #works
> myEcho.sh "ls -al|grep *.sh" #fail
# Output:
#ls: invalid option -- |
#Try 'ls --help' for more information.
> myEcho.sh "ls -al|grep "*.sh"" #fail
# Output:
#ls: invalid option -- |
#Try ls --help' for more information.
> myEcho.sh 'ls -al|grep *.sh' #fail
# Output:
#ls: invalid option -- |
#Try 'ls --help' for more information.

I have a python script on one server (serv_one) and I am trying to execute it remotely from another (serv_two). The python script takes an argument with spaces. If I execute it locally:
Code:
foo@serv_one> script.py --o "arg one"
"arg one" is preserved, of course. ( argv = [ '--o', 'arg one' ] )
However, when I execute it remotely:
Code:
foo@serv_two> ssh ... foo@serv_one script.py --o "arg one"
the double quotes around "arg one" are dismissed ( argv = [ '--o', 'arg', 'one' ]. I've tried many combinations of single quotes/double quotes/backslashes, etc, to no avail. One hack solution I came up with, since I have the flexibility, was to replace all spaces in the quoted argument with a character that would be invalid in the argument (before the ssh call), and replace those with spaces in script.py. I would probably like to avoid this solution if at all possible.

Examples:
Code:

operator is -gt
remcount is
^ value missing!
Code:
$ ./test.sh -b -c 2
operator is -lt
remcount is
^ value missing!
Yet when "-c" is the first argument, its value is present:
Code:
$ ./test.sh -c 2 -b
operator is -lt
remcount is 2
What could I do to ensure the value of "-c" is picked up regardless of the argument order?

I have a template similar to the following.
Code:
template <charT>
virtual void do_get_date(charT* = "str")
{ ... }
As you can see we have a problem. If we use a wchar_t instead the string wont be formatted right we need to prefix L in front. If we use char16_t we need to prefix a u in front. Is there a was to make the generic without resorting the the std::string class?

I am running Red Hat with 2.6.18-194.8.1.el5PAE kernel version. I am trying to run encryptfs to encrypt a partition on my hard drive. One of the kernel modules necessary is the md5.ko. I noticed it wasn't loaded in when doing an lsmod. I tried running modprobe md5 and it fails to load:
[root@ ~]# /sbin/modprobe -v md5
insmod /lib/modules/2.6.18-194.8.1.el5PAE/kernel/crypto/md5.ko
FATAL: Error inserting md5 (/lib/modules/2.6.18-194.8.1.el5PAE/kernel/crypto/md5.ko): Invalid argument
I ran dmesg and grepped for md5, but I didn't see anything in there.

I boot several Redhat based distributions, Fedora 15, Fedora 14, CentOS, Scientific Linux, Redhat and occasionally something non-Redhat based like Ubuntu and Debian. Out of habit and preference I frequently set up partitions to be auto mounted at boot through fstab. Somewhere in time something went seriously wrong with the CentOS install. There are a ton of permission denied errors while booting CentOS (text style boot) mostly regarding shared libraries. The system will boot to the desktop and everything looks OK but some things don't work. I can't update the system because I have no network connection. I obviously can't get to the Internet or get e-mail. I can open a VT but can't log in as regular user or root.
Permission denied in both instances. I didn't make any drastic changes to the CentOS system, just minor tweaks. The culprit in my opinion is a combination of the fact that one of the other Linux systems did an SELinux relabel while booting and the CentOS partition was already mounted. Since the CentOS partition was mounted it too was relabeled. I can't prove this. If there's a way to prove it then I just don't have the skills or knowledge to do so. It's basically a theory based on what I know I've done with the several installed distributions. This is not a rant nor is it a request for help. Just a comment. An assumption, hopefully a correct assumption. The CentOS install was working flawlessly until something happened and I think that something was the SELinux relabel.

In a script, when I enter "echo $1" the first argument is outputted. When I enter:
a=1
echo "$$a"
The output is just "$1", not the first argument. If I enter:
a=1
b=$$a
echo $b
The output is still "$1" and not the first argument. How can I get echo to output the first argument without use "$1" directly?
