while loop with 3 ifs

sigh2010 · #1 (**permalink**) 07-20-2009

im messing up somehwere...and can't seem to clean up the script...for it to work

objectives:

1. check for today's file, and sleep 30 secs between retries
2. only allow 5 tries before script should fail.
3. if today's file found, wait 30 seconds for it to process..

code:

Code:

count=0
while [ $count -lt 5 ]
do
    count=`expr $count + 1`
    echo "Try $count"
    RUNDATE=`date "+%h%e"`
    filedate=`ls -l file.xml | awk '{print $6,$7}`
    if [ $count -ge 5 ]
      echo "Too many retries"
      echo "Please check source why the file is not imported"
       exit 0
    else           
     if [ "$filedate" = "$RUNDATE" ] 
     echo "Today's file is ready for processing."
         echo "Sleeping 30 secs to allow it to process "
      sleep 30
           break
     fi
    fi
    if [ "$filedate" != "$RUNDATE" ]
      echo "File date in directory is $filedate and today's date is $RUNDATE. They don't match"
  echo "Sleeping 30 seconds and trying again; 5 tries is my limit"
          sleep 30
    fi
done

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

count=`expr $count + 1`

this is the if - else construct

Code:

if [ $count -eq 2 ]
then
echo "yes"
else
echo "no"
fi

missing ' then '

Code:

 if [ $count -ge 5 ]; then

is the correct syntax.

Btw, if you use sed -x to debug, life would be easy.

count will never get greater that 4, first if is not required.

$RUNDATE and $filedate will never match here, check why.
