UNIX for Dummies Questions & Answers

no.. just post the method dadd code here and what argument you are passing to the shell script ?

what is the value of str ( before passing to the system method )

And post the shell script code also.

GTK program is:

#include<gtk/gtk.h>
#include<stdio.h>
#include<stdlib.h>
gchar *chardadd1=NULL,*chardadd2=NULL;

void dadd(GtkWidget *widget, gpointer label)
{
char str[512];
int x;
sprintf(str,"sh st1.sh %s ",chardadd1);
x=system(str);
}
int main(int argc,char *argv[])
{
int i;char buf[128];


GtkWidget *window;
GtkWidget *tabledadd;
GtkWidget *labeldadd1;
GtkWidget *entrydadd1;
GtkWidget *buttondadd;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_window_set_title(GTK_WINDOW(window), "GtkEntry");

gtk_container_set_border_width(GTK_CONTAINER(window), 50);
entrydadd1 = gtk_entry_new();
tabledadd = gtk_table_new(3, 2, FALSE);
gtk_container_add(GTK_CONTAINER(window), tabledadd);
labeldadd1 = gtk_label_new("group name");
buttondadd=gtk_button_new_with_label("click me");
gtk_table_attach(GTK_TABLE(tabledadd), labeldadd1, 0, 1, 0, 1,
GTK_FILL | GTK_SHRINK, GTK_FILL | GTK_SHRINK, 5, 5);
gtk_table_attach(GTK_TABLE(tabledadd), entrydadd1, 1, 2, 0, 1,
GTK_FILL | GTK_SHRINK, GTK_FILL | GTK_SHRINK, 5, 5);

gtk_table_attach(GTK_TABLE(tabledadd), buttondadd, 0, 2, 2, 3,
GTK_FILL | GTK_SHRINK, GTK_FILL | GTK_SHRINK, 5, 5);

chardadd1=gtk_entry_get_text(GTK_ENTRY(entrydadd1));
gtk_widget_show(window);
gtk_widget_show(tabledadd);
gtk_widget_show(labeldadd1);
gtk_widget_show(entrydadd1);
gtk_widget_show(buttondadd);

//dadd will be called in the below statement
g_signal_connect(buttondadd, "clicked",G_CALLBACK(dadd), entrydadd1);

g_signal_connect(window, "destroy",G_CALLBACK(gtk_main_quit), NULL);
gtk_main();
return 0;
}


Shell script is:

IN=$1
c=`echo $IN | tr -dc ';' | wc -c`
b=(`awk -F';' '$1=$1' <<<$IN`)
i=0
while [ $i -le $c ];
do
d=(`echo ${b[i]} | tr '-' ' '`)
a=${d[0]}
b=${d[1]}

while [ $a -le $b ];
do
echo $a
a=`expr $a + 1`
done
i=`expr $i + 1`
done




The input that has to be given in text entry should be in the format
"1-10;20-30;40-50;60-70"

and this will be passed to shell script and it gets splitted there and the numbers from 1-10,20-30,40-50,60-70 (as per the given input) will be displayed.
The shell script alone is working fine, but if I give more inputs through the text entry then it's not getting passed form Gtk program to shell program

make the colored changes in your shell script.

Code:

 
IN=$1
c=`echo $IN | tr -dc ';' | wc -c`
b=`awk -F';' '$1=$1' <<<$IN`
i=0
while [ $i -le $c ];
do
d=`echo ${b[i]} | tr '-' ' '`
a=${d[0]}
b=${d[1]}
while [ $a -le $b ];
do
echo $a
a=`expr $a + 1`
done
i=`expr $i + 1`
done

can you change this also.

Code:

sprintf(str,"sh st1.sh \"%s\"",chardadd1);

It's returning errors if dont keep the braces..

ok, keep the brace.

Did you print the str ? (before you passing to the system ) to make sure what you exactly executing...

It's (value of str) printing garbage values if I give large number of inputs..

can you answer for my questions

1) post the value of str
2) give the small number of input.
3) what is the value of chardadd1 ? ( print after this line -- chardadd1=gtk_entry_get_text(GTK_ENTRY(entrydadd1))
4) And the same is printed inside the dadd method ?
5) inside the shell script, add echo $IN after the IN=$1 and check whether the correct input is passed or not.
6) what is the datatype of chardadd1 ?
