When I grep for the one process, that is all that we need to show that the database is accepting new connections.

Normally, if you do a ps -ef | grep <process> it brings back a bunch of running processes.

Code:
root  221352  581886   0   Nov 21      -  0:46 process-database: db (idle) 
    root  262310  581886   0   Nov 21      -  0:37 process-database: db (idle) 
    root  290860  581886   1   Nov 21      -  0:41 process-database: db (idle) 
    root  553002  581886   0   Nov 21      -  0:46 process-database: db (idle) 
    root  581886       1   0   Nov 21      -     0:05 process-database: (accepting)

If I do this command..
Code:
ps -ef | grep '[p]rocessd.*(accepting)

It returns what I am looking for

---------- Post updated at 03:14 PM ---------- Previous update was at 11:45 AM ----------

I did my best to clean up the code. Can anyone help with including a for loop in this. It needs to run 5 times (If the first argument is false and the database isnt accepting connections) If it gets past the first part it can just run then.

Code:
 
database=$(ps -ef | grep '[d]atabase.*(accepting)' | awk '{ print $2}')
if [ -n "$database" ]
 then
      echo "The database is accepting connections"
 
  process=$(ps -ef | grep [p]rocess | awk '{ print $2}')
   if [ -n "$process" ]
    then
         
         echo "Start  Automated Processes"
          ###START OTHER SCRIPT###
    else
          echo "Start Processe".
          cd /home/user/dir/process
          sleep 10
          ###START OTHER SCRIPT###
   fi

   
 else
      echo "The database is not accepting connections..."
  sleep 30
 
fi
 
done

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.
