I agree. Thanks for the info. I need to brush up on my trapping instead of always using exit 1 to catch errors.
I have one parent and about 150 children. If I remove the || exit 1 from the parent then I'm in big trouble because the previous child needs to complete sucessfully before the next one is run or it will snowball on me.
I just need to check that $variable = $variable before the child is run (or before the child actually gets going), but $variable is ever changing in each script so I can't set it from the parent.. If $variable != $variable then it needs to be skipped and the next child in line needs to be ran... I'll hack it for now and put it on my TODO list...
Code:
set -e
variable1=1
variable2=2
if [ "$variable1" = "2" ]; then
bail=yes
elif [ "$variable1" = "1" ]; then
true
fi
if [ "$bail" != "yes" ]; then
# lots more stuff to run in this child script
fi
I don't follow what these are...

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.
