Can someone please tell me how to modify/add to this code so that it recognizes UNIX command options (all beginning with "-") and executes the command with options?
Code:
#include<stdio.h>
#include<stdlib.h>
int main(int argc, char *argv[])
{
int i;
system("stty -echo");
for(i=1; i<argc; i++)
{
printf("The command %s is executed.\n", argv[i]);
system(argv[i]);
}
system("stty echo");
return 0;
}
I am looking to populate an (associated) array with a command line argument.
The command line would look something like this:
alert -action test -priority '10' -module test_module . . .
The associated array would look like this after the data is read in
flag=(action=test
priority=10... (1 Reply)

Hi,
I am writing a shell script to build Java options dynamically in a variable array and pass them to java.exe. If an option value contains a space, I cannot find a way to get it interpreted correctly. Here is my example:

Being new to awk I have a really basic question. It just has to be in the archives but it didn't bite me when I went looking for it.

Hi,
I have this command in a shell script and I can get it to echo ok, but when I try to execute the command I get a "file not found" error. Which is strange because, if I copy and paste the same command at the cli it works ok.

cdk_params(3) Library Functions Manual cdk_params(3)NAME
cdk_params - Cdk command-line parsing
SYNOPSIS
cc [ flag ... ] file ... -lcdk [ library ... ]
#include <cdk.h>
int CDKparamNumber (
CDK_PARAMS *params,
int option);
int CDKparamNumber2 (
CDK_PARAMS *params,
int option,
int missing);
char * CDKparamString (
CDK_PARAMS *params,
int option);
char * CDKparamString2 (
CDK_PARAMS *params,
int option,
char *missing);
void CDKparseParams (
int argc,
char **argv,
CDK_PARAMS *params,
char *options);
int CDKparsePosition (
char *string);
int CDKparamValue (
CDK_PARAMS * params,
int option,
int missing);
DESCRIPTION
These are a set of functions used to implement the command-line utilities and demonstration programs for Cdk. Rather than set the pro-
grams' options at initialization, they construct a simple database which holds the common parameters using CDKparseParams().
AVAILABLE FUNCTIONS
CDKparamNumber
Retrieves an integer (or boolean) option value from the parsed command-line.
CDKparamNumber2
Retrieves an optional integer (or boolean) value from the parsed command-line. If the command line option is not present, the missing
value is used.
CDKparamString
Retrieves a string option value from the parsed command-line.
CDKparamString2
Retrieve an optional string option value from the parsed command-line.
CDKparamValue
Retrieve an integer (or boolean) option value from the parsed command-line.
CDKparseParams
Parse the given argc/argv command-line, with the options passed to getopt()'s 3rd parameter.
CDKparsePosition
Parse the string as one of CDK's positioning keywords, or an actual position.
