Homework and Emergencies Emergency UNIX and Linux Support Waiting for wildcard filename to exists in while loop Post 302916887 by Amey Joshi on Friday 12th of September 2014 11:21:09 AM

Thanks all for the reply!!

Sorry for the confusion. Actually our file name will have datetime for e.g Trigger_09122014103030.done.

I am creating script which will wait until this file appears. Since this file is datetime appended, I can not give exact file in while loop(while running daily), that's reason the I am trying to check if the file name with Trigger*.done exists.

Command :-
Code:
while [ ! -f "${actualfile}" ]; do

When I add the 'Trigger_09122014103030.done' in the mentioned source location (when script is in while loop) it does not come out of the while loop
But when I add 'Trigger*.done' it comes out of the while loop.
I think 'while' command searches for the exact file name

Appreciate all your help!!

Thanks

TRIGGER(7) SQL Commands DROP TRIGGER(7) NAME
DROP TRIGGER - remove a trigger SYNOPSIS
DROP TRIGGER name ON table [ CASCADE | RESTRICT ] INPUTS name The name of an existing trigger. table The name (optionally schema-qualified) of a table. CASCADE Automatically drop objects that depend on the trigger. RESTRICT Refuse to drop the trigger if there are any dependent objects. This is the default. OUTPUTS DROP TRIGGER The message returned if the trigger is successfully dropped. ERROR: DropTrigger: there is no trigger name on relation "table" This message occurs if the trigger specified does not exist. DESCRIPTION
DROP TRIGGER will remove an existing trigger definition. To execute this command the current user must be the owner of the table for which the trigger is defined. EXAMPLES
Destroy the if_dist_exists trigger on table films: DROP TRIGGER if_dist_exists ON films; COMPATIBILITY
SQL92 There is no DROP TRIGGER statement in SQL92. SQL99 The DROP TRIGGER statement in PostgreSQL is incompatible with SQL99. In SQL99, trigger names are not local to tables, so the command is simply DROP TRIGGER name. SEE ALSO
