What I am about to say assumes that table temp1 is a file.

If it is then:

1. At the end of script B ensure that temp1 is either deleted or renamed so that it doesn't exist anymore.

2. At the start of script B, "test" (see man pages) to see if the file temp1 exists and if it doesn't then "sleep" (see man pages) for, say, 600 seconds to sleep the script. Only when temp1 exists will script B continue processing.

The above also assumes that temp1 is created fairly instantly so will either exist or not exist. If temp1 is created slowly, then get script A "touch" (see man pages) a file to use as a flag to script B which can then "test" for the existance of the flag file instead. Script B should delete the flag file before it finishes.

Hope that helps (and I have succeeded in making that clear enough).

Post any further questions.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
