well said don, thanks. i like your style.
here is a rewrite:

I have a script that will not show the current pid.

the script below uses a simple if statement.

the if statement is suppose to restart another process (it does!)

once the 2 script is restarted ( it stopped, this script restarts it)
it produces a pid.

it did NOT have a pid, thus needed to be restarted.
This script below does that.

problem: i can not grep/grab/whatever you want to call it, and mailx that new pid.

that's my problem: can NOT grab the new pid.

I am at work now, i will try your suggestion:
pid=$!

***sh -x stdout BEFORE i kill pid to simulate it's not running***



Code:
$ sh -x sig-ps-restart7.sh
+ stty intr ^c
+ BATDIR=/usr/script8/batch
+ BATNAM=bat_fstsi61c.sh
+ BATPF=bat_fstsi61.pf
+ BATSVC=SIGTEST
+ BATPF=bat_fstsi61.pf
+ SERVER=PHANTOM
+ SDIR=/apps/sigmon/dvl/fst61
+ SIN=/apps/sigmon/dvl/fst61/in
+ SPROC=/apps/sigmon/dvl/fst61/proc
+ SLOG=/usr/script8/batch/LOGS
+ SMAIL=/usr/script8/batch/EMAILS
+ SMAILER=petey
+ export BATDIR BATNAM BATSVC BATPF SERVER SDIR SIN SPROC SLOG SMAIL SMAILER
+ + ps -ef
+ grep bat_fstsi61.pf
+ grep -v grep
+ awk -F  {print $2}
pid=20599
+ echo 20599
20599
+ [ 20599 =  ]
+ echo service is ok
service is ok
+ pid=

*** sh -x stdout AFTER i kill pid to simulate it's not running ***

first i kill the current pid that is already running prior:


Code:
kill 20599

Code:
$ sh -x sig-ps-restart7.sh
+ stty intr ^c
+ BATDIR=/usr/script8/batch
+ BATNAM=bat_fstsi61c.sh
+ BATPF=bat_fstsi61.pf
+ BATSVC=SIGTEST
+ BATPF=bat_fstsi61.pf
+ SERVER=PHANTOM
+ SDIR=/apps/sigmon/dvl/fst61
+ SIN=/apps/sigmon/dvl/fst61/in
+ SPROC=/apps/sigmon/dvl/fst61/proc
+ SLOG=/usr/script8/batch/LOGS
+ SMAIL=/usr/script8/batch/EMAILS
+ SMAILER=petey
+ export BATDIR BATNAM BATSVC BATPF SERVER SDIR SIN SPROC SLOG SMAIL SMAILER
+ + ps -ef
+ grep bat_fstsi61.pf
+ grep -v grep
+ awk -F  {print $2}
pid=
+ echo

+ [  =  ]
+ cd /usr/script8/batch
+ pid=3951
+ mailx -s 'PHANTOM' 'bat_fstsi61c.sh' PID '3951' was started petey
+ . bat_fstsi61c.sh
trunc'd......
+ exec /apps/dlc/bin/our-data-base-here -b -p /tmp/job003954 -pf /usr/script8/pf_files/bat_fstsi61.pf

it appears to work for the pid part thanks!!!

BUT... it now needs to close: here is the ps -ef|grep petey


Code:
petey  3952  3944  0 09:29:49 pts/tt    0:00 mailx -s 'PHANTOM' 'bat_fstsi61c.sh' PID '3951' was started petey
  petey  3944 29979  0 09:29:49 pts/tt    0:00 sh -x sig-ps-restart7.sh
  petey 24556 24555  0  Jun  4  pts/tr    0:00 -sh
  petey  3951  3944  0 09:29:49 pts/tt    0:02 /apps/dlc/bin/our-data-base-here -b -p /tmp/job003954 -pf /usr/script8/pf_files/bat_fstsi61.pf

so now, this job will be put into a cron job, IF i we can make the mailx actually finish.. it seems to be sitting there ...

sorry had to leave other script for security reasons.. hope you understand...
