advice on shell script

Shell Programming and Scripting
1

Hello,
I have this script running on cron every 20 minutes.
By 12pm daily, our system is expecting all input files to be uploaded by the script.
After this cutoff time, the script would still be running though, but i need some kind of alerts/logs to know which input files weren't received for that day.

These daily input files will be sent to us in different timings:
INPUT_FUBX
INPUT_FSTV
INPUT_FGBR
INPUT_FJMT
INPUT_FWRP
INPUT_FQZN
INPUT_FPBT
INPUT_FMHQ
INPUT_FDGP

Below are some lines from my script:

DATE=`date +%Y%m%d_%H%M%S`
PATH=/my/home/directory/path/
ARCHIVE=/my/archive/directory/path/
LIST="INPUT_FUBX INPUT_FSTV INPUT_FGBR INPUT_FJMT INPUT_FWRP INPUT_FQZN INPUT_FPBT INPUT_FMHQ INPUT_FDGP"

for i in $LIST
do
if [[ ! -a $PATH/$i ]]
then
echo 'Input file '${i}' still missing.'
elif [[ -s $PATH/$i ]]
then
## Call upload processing functions here ##
mv $PATH/$i $ARCHIVE/$i_$DATE
fi
done

With the above, I was able to know which input files were still missing, but only during those certain time specified in cron timings.
I won't know which among the input files were missed out totally after the cutoff time for the day.
Any ideas here?

Also, is there a way to make this script flexible so as whenever we add to the list of input files, say add another file named INPUT_FTBS, I don't need to modify the LIST variable in the script everytime.

Appreciate it.
Thanks much.

(a) Much easier to read a script when you use codetags. After pasting in script text, highlight the script and select the '#' icon - which will maintain spacing of your script.

(b) You could store the variable names in a file, and then use the file to set all of the names. See the following

> cat sample2
INPUT_FUBX
INPUT_FSTV
INPUT_FGBR
INPUT_FJMT
INPUT_FWRP
INPUT_FQZN
INPUT_FPBT
INPUT_FMHQ
INPUT_FDGP
> cat sample2 | tr "\n" " "
INPUT_FUBX INPUT_FSTV INPUT_FGBR INPUT_FJMT INPUT_FWRP INPUT_FQZN INPUT_FPBT INPUT_FMHQ INPUT_FDGP  
> sample2x=$(cat sample2 | tr "\n" " ")
> echo $sample2x
INPUT_FUBX INPUT_FSTV INPUT_FGBR INPUT_FJMT INPUT_FWRP INPUT_FQZN INPUT_FPBT INPUT_FMHQ INPUT_FDGP

(c) Change the logic of your loop to read from the file [as you created in (b)]

while read zf
  do
  echo $zf  #showing the variable
  blah - blah
done <sample2
