Top Forums Shell Programming and Scripting exiting a child without stopping the parent Post 302136820 by madpenguin on Wednesday 19th of September 2007 10:31:41 PM

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

Ugly but will work. Thanks again.

XtUnmanageChildren(3X)						   XT FUNCTIONS 					    XtUnmanageChildren(3X)

NAME
XtUnmanageChildren - unmanage children SYNTAX
typedef Widget *WidgetList; void XtUnmanageChildren(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 XtUnmanageChildren 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, XtUnmanageChildren performs the following: - Ignores the child if it already is unmanaged or is being destroyed and marks it if not. - If the child is realized, it makes it nonvisible by unmapping it. o Calls the change_managed routine of the widgets' parent after all children have been marked if the parent is realized. XtUnmanageChildren does not destroy the children widgets. Removing widgets from a parent's managed set is often a temporary banishment, and, some time later, you may manage the children again.
