UNIX for Dummies Questions & Answers

Hi,

I have a script that finds the application logs from the previous day and sends it to another server via ftp.
The code is something like this:
yest_date=`TZ=CST+24 date "+%b %d"`
logdir=/app/logs
logs=app*.log
tmpdir=/tmp
cd $logdir
for i in `ls -1 $logs`
do
chkstr=`ls -1l $i | grep "$yest_date"
if [ "$chkstr" != "" ]
then
tar -cvf $tmp/$yest_date-logs.tar $file



The script works fine when ran manually and via cron. But when ran through a job scheduler, UC4, the script fails every 15th - 20th of the month! Consistently! It looks like from the script log, the code just did not execute. The log shows that it cannot find the .tar file when it attempted to ftp.
My OS is AIX and shell is Korn shell. The job scheduler uses the same login as when I execute the script manually or when ran thru cron. The AIX admins found no processes/jobs that could affect the script execution. What else could I check? Any ideas is much appreciated!

how many log files are in there? lots and lots and lots?

if so:

for i in `ls -1 $logs`

might be giving "arglist too long error"

are you seeing any errors in the UC4 execution logs?

If not - - - then the problem is probably NOT your script and
is most likely something in UC4.

chkstr=`ls -1l $i | grep "$yest_date"`
There is a backtick missing on this line.

Design point: Does the filename contain the date (MMM DD) , or are you looking for the date in the directory listing? ls minus one .. or ls minus ell ?


There are many continuity and syntax errors in the script as posted.

It sets $tmpdir , then uses $tmp .
Where is $file set ?
for ... do ... done
if ... then ... fi
Variable $i will not work if the filename(s) contain spaces.

Please post the actual script !
