UNIX for Dummies Questions & Answers

Here is an example of the case statement: Note that the double semi colons are required after each case in the statement. the * is the default case.

Code:

case ${cont} in 
Y|y) commands to execute 
 when value matches pattern1 
 ;; 
N|n) commands to execute 
 when value matches pattern2 
 ;; 
... 
*) default commands to execute 
 when value matches patternn 
 ;; 
esac

Thanks for the patients!

I didn't try you script but just want to ask few questions on your script.

From the beginning, you 'cd to $SSM_IN_DIR' and then store this path to $fail_path. After this, you 'cd $fail_path | ls -lsf'. Why don't simply use ls -lsf?

Code:

elif [[ ${batch_count} -lt 2 ]]

If the batah_count is 0, I think it also pass this code. So you may make a code at the beginning:

batch_count=`ls | wc -w` #No need to sort in your case
if [[ $batch_count = 0 ]]; then
echo "There are no failed files in the ${fail_path} directory.
exit
fi

It is used to replace your code where in the last part. I think that if nothing to do. Quit from the script earlier rather than read through all content but do nothing.

Code:

elif [[ ${batch_count2} -lt 1 ]]

Actually I didn't know the useful of batch_count2. Because in your script I just found three cases.
batch_count = 0 No remove
"batch_count = 1" and "batch_count > 1" Both remove file but only different in echo message.

So "batch_count2 -lt 1" actually same as "batch_count = 0"

From your script, "batch_count2 -gt 1" might not work because if batch_count is 2.

Agree with google, using 'case' may more convenience in your case.
