Using Awk in shell script to extract an index of a substring from a parent string
Hi All,
I am new to this shell scripting world. Struck up with a problem, can anyone of you please pull me out of this.
Requirement : Need to get the index of a substring from a parent string
Eg : index("Sandy","dy") should return 4 or 3.
My Approach :
I used Awk function index to achieve this
when i excecute this in command line
awk 'BEGIN { print index("Attempting to connect to ipaddr: 127.0.0.1 IllegalUrl_110707092804.txt Succeeded with no errors.","Succeeded with no errors") }'
72
if gives me correct output which is 72
but in shell script it always returns 0.
$a="Attempting to connect to ipaddr: 127.0.0.1 IllegalUrl_110707092804.txt Succeeded with no errors."
$b="Succeeded with no errors"
echo "`awk 'BEGIN { print index($a,$b) }'` "
Can anybody please tell what is the problem or suggest an alternate approach.
Many Thanks,
Sandeep

xtcreatepopupshell
XtCreatePopupShell(3) XT FUNCTIONS XtCreatePopupShell(3)
NAME
XtCreatePopupShell, XtVaCreatePopupShell - create a popup shell
SYNTAX
Widget XtCreatePopupShell(String name, WidgetClass widget_class, Widget parent, ArgList args, Cardinal num_args);
Widget XtVaCreatePopupShell(String name, WidgetClass widget_class, Widget parent, ...);
ARGUMENTS
args Specifies the argument list to override the resource defaults.
name Specifies the text name for the created shell widget.
num_args Specifies the number of arguments in the argument list.
parent Specifies the parent widget.
widget_class
Specifies the widget class pointer for the created shell widget.
... Specifies the variable argument list to override the resource defaults.
DESCRIPTION
The XtCreatePopupShell function ensures that the specified class is a subclass of Shell and, rather than using insert_child to attach the
widget to the parent's children list, attaches the shell to the parent's pop-ups list directly.
A spring-loaded pop-up invoked from a translation table already must exist at the time that the translation is invoked, so the translation
manager can find the shell by name. Pop-ups invoked in other ways can be created ``on-the-fly'' when the pop-up actually is needed. This
delayed creation of the shell is particularly useful when you pop up an unspecified number of pop-ups. You can look to see if an appropri-
ate unused shell (that is, not currently popped up) exists and create a new shell if needed.
