#    root  82522      1   0   Nov 08      -  0:59 x_jobserver 10 v001
#    root 159334 102986   0 08:51:12  pts/6  0:00 grep x_jobserver 10 v001
# count lines
pg /jobstatv001.txt|awk '
/^ / {
   ++linenum
}'
if (linenum = 4)
 exit 1
else if (linenum = 0)
 cp /Medic/db/v001/jobserver.log /Medic/db/v001/jobserver001.log
 startjs v001
fi

this is what I get:
Code:
jschk.sh[17]: syntax error at line 19 : `else' unexpected

The file jobstatv001.txt is created.

I have also tried just a plain "if/else/fi" but still get the syntax error.
Using IBM AIX.
Another way to do the job:
Code:
linenum=$(ps -ef | awk '/x_jobstat 10 v001/ || /x_jobserver 10 v001/{n++}END{print n}')

if [ "$linenum" -eq 4 ]
then
  exit 1
elif [ "$linenum" -eq 0 ]
then
  cp /Medic/db/v001/jobserver.log /Medic/db/v001/jobserver001.log
  startjs v001
fi

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
