Returning values from child to parent shell
I need to send the status from child shell failure to parent shell. I would like to know how could we accomplish this.
My parent.sh is as below:
#!/bin/ksh
set -x
echo "I am in parent shell now..."
child.sh
ret_stat=$?
echo "rest_stat=$ret_stat"
echo "I am below parent shell end..."
My child.sh is as below:
#!/bin/ksh
set -x
cho "I am in child shell now..." > test.log 2>&1
if [[ $? -ne 0 ]]
then
exit 100
fi
echo "I am in child shell end.."
I would like to capture the failure status from child.sh The statement in bold in child.sh is mistyped. I would like the 100 (failure) status sent to parent shell. Note that I would also like to re-direct my output to test.log at the same time.
Per above, I get success(0) status in my parent.sh ret_stat variable after the call to child.sh. This is happening because of redirection into the log file.
I would like the child shell to return 100 (failure) to parent ret_stat variable.
Let me know how would we accomplish this with the re-direction to log in the child.
Hope I made my self clear.
Thanks,
AC

xtmanagechildren
XtManageChildren(3X) XT FUNCTIONS XtManageChildren(3X)
NAME
XtManageChildren - manage children
SYNTAX
void XtManageChildren(children, num_children)
WidgetList children;
Cardinal num_children;
ARGUMENTS
children Specifies a list of child widgets.
num_children
Specifies the number of children.
DESCRIPTION
The XtManageChildren function performs the following:
o Issues an error if the children do not all have the same parent or if the parent is not a subclass of compositeWidgetClass.
o Returns immediately if the common parent is being destroyed; otherwise, for each unique child on the list, XtManageChildren ignores
the child if it already is managed or is being destroyed and marks it if not.
o If the parent is realized and after all children have been marked, it makes some of the newly managed children viewable:
- Calls the change_managed routine of the widgets' parent.
- Calls XtRealizeWidget on each previously unmanaged child that is unrealized.
- Maps each previously unmanaged child that has map_when_managed True.
Managing children is independent of the ordering of children and independent of creating and deleting children. The layout routine of the
parent should consider children whose managed field is True and should ignore all other children. Note that some composite widgets, espe-
cially fixed boxes, call XtManageChild from their insert_child procedure.
If the parent widget is realized, its change_managed procedure is called to notify it that its set of managed children has changed. The
parent can reposition and resize any of its children. It moves each child as needed by calling XtMoveWidget, which first updates the x and
y fields and then calls XMoveWindow if the widget is realized.
