Waiting for wildcard filename to exists in while loop
Hi Experts,
We are developing a script which will wait for the trigger file(with datetime in the trigger file name).
But the problem is when I use 'while' loop to wait for the file, it waits for the filename with wilcard in it that is wait for 'Trigger*.done' file.
Below is the script
This script works when I touch 'Trigger*.done' file in the source. Is there anyway to loop until the filename(with wildcard character) exists?

I'm sure this is by design, but using something like
for f in dir/*
do echo $f
done
produces unexpected (to me) results if run against an empty directory. I'd have expected it to not execute the loop, but it actually calls it with f set to 'dir/*'.
Now I know that I'm trying to protect... (2 Replies)

alter_trigger
ALTER TRIGGER(7) SQL Commands ALTER TRIGGER(7)NAME
ALTER TRIGGER - change the definition of a trigger
SYNOPSIS
ALTER TRIGGER name ON table RENAME TO newname
DESCRIPTION
ALTER TRIGGER changes properties of an existing trigger. The RENAME clause changes the name of the given trigger without otherwise changing
the trigger definition.
You must own the table on which the trigger acts to be allowed to change its properties.
PARAMETERS
name The name of an existing trigger to alter.
table The name of the table on which this trigger acts.
newname
The new name for the trigger.
NOTES
The ability to temporarily enable or disable a trigger is provided by ALTER TABLE [alter_table(7)], not by ALTER TRIGGER, because ALTER
TRIGGER has no convenient way to express the option of enabling or disabling all of a table's triggers at once.
EXAMPLES
To rename an existing trigger:
ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;
COMPATIBILITY
ALTER TRIGGER is a PostgreSQL extension of the SQL standard.
