control over shell script
Hi..
I have a perl program that uses "system" to execute a shell script called startengine. The script "startengine" itself calls a lot of other smaller scripts to setup the engine etc. It finally has to execute ./engine which is another shell script which is long and takes a long time to complete processing.
The "startengine" script looks like this
#!/bin/bash
echo In shell script............
/usr/agjy/bin/cleartool setview $1 <<END
cd /vobs/eng/work
. ./setup host-dbg gw
cd \$ENG_TARGET_ROOT/home/bin
pwd
/home/agjy/bin/stopAll
/home/agjy/bin/cleanup
./engine 2>&1 |tee $2
My problem is that the system call returns back to perl script without waiting for ./engine to finish processing..
I have tried sleep in the perl script which works only sometimes depending on machine speed. Another problem is that ./engine is a waiting process- ie if it runs correctly it should say "waiting for connection.. " and wait for input. the output of ./engine is written into the logfile ($2). The perl script then parses that
logfile looking for the "waiting for connection" string and proceeds to send input to the engine or shut it down depending on if string was matched or not.
I need something that will make sure ./engine is completely processed before control returns to perl script..
I hope i have made the problem clear and would really appreciate any help with this..
Thanks,
JLJ

NAME

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.
