Shell Programming and Scripting

Hi,

Am working in a filenet domain where we are using AIX as our terminal to run the jobs and schedule the shell scripts to run . In my previous post regarding the "Log modification with finding errors" https://www.unix.com/shell-programmin...nt-time-2.html Gabriel has helped me thoroughly to complete the entire script. Thanks for the help Gab. The script was sent to my leads to get their reviews. Will keep you posted there if i get any updates.

The next thing which i started here to begin our conversation is - In filenet there are 4 image services HPII COLD POST BES.

When we give ps -ef|grep HPII , it will display a output ending with ./HPII_import and ./HPII_val.

When we give ps -ef|grep cold , it will display a output ending with ./cold_daily.ksh and COLD_3770.

When we give ps -ef|grep bes_commit , it will display a output ending with bes_commit 1 and bes_commit 2

When we give ps -ef|grep post , it will display a output ending with
./postindex_daily.ksh

I need to use a IF condition added with the above ps statements, if the resulting output comes it should send us a status , for HPII - " HPII is running fine without any issues ". for post - "POST Index services is fine" . same for other too.

Could some one help me out with this IF conditional statement added with PS . I should schedule this script for every 1 hour. NOTE: This should work in AIX terminal.

Use -q (quiet option of grep):

Code:

ps -ef | if grep -q '[H]PII'
then
   echo "HPII is running fine without any issues"
fi

Note square brackets avoid grep matching it's own arguments in the ps listing.

Thanks for the reply,

So do i need to add the script by square brackets as you said
ps -ef | if grep -q '[H]PII' then echo "HPII is running fine without any issues" fi
ps -ef | if grep -q '[p]ost' then echo "HPII is running fine without any issues" fips -ef | if grep -q '[b]es_commit' then echo "BES is running fine without any issues" fips -ef | if grep -q '[c]old' then echo "COLD is running fine without any issues" fi

Please wrap your code in [code] tags! (At the top of the WIKI editor.)

Square brackets is a trick only for ps -ef | grep, so YES in this case. pgrep is a smart alternative on many platforms.
--
I would use if at the beginning of the command block, aligned with the fi at the end of the command block.
Either #1

Code:

ps -ef |
if grep -q ...
then
 ...
fi

Or #2

Code:

if ps -ef | grep -q ...
then
 ...
fi

I wonder if there is any functional difference between #1 and #2, because in #2 the resulting exit status is from the last command in the pipe.
In fact I am used to #2.

I'd be surprised if ps -ef|grep cold yielded COLD_3770 (unless GREP_OPTIONS is set).
And, for HPII to be considered running fine, do you need both processes (_import and _val)? Then you should test for both of them. Same is valid for the other applications.

Thanks for the reply ,

Yeah when i give ps -ef|grep cold it shows the output of cold_3770 (sorry its not COLD_3770). And of course i need to validate 2 HPII process (HPII_val and HPII_import). Could you please help me out with this.

Try

Code:

ps -ef|
awk     '/HPII_val/     {HPV=1}
         /HPII_imp/     {HPI=1}
         /cold_dai/     {CDD=1}
         /cold_377/     {CD7=1}
         /bes_commit 1/ {BC1=1}
         /bes_commit 2/ {BC2=1}
         /post_ind/     {POI=1}
         END            {if (HPV && HPI) print "HPII is running fine without any issues"
                         if (CDD && CD7) print "COLD is running fine without any issues"
                         if (BC1 && BC2) print "BES is running fine without any issues" 
                         if (POI)        print "POST Index services is fine"
                        }
        '

and report back.
