Hi All:

I am a newbie for ksh scripting.My code doesn't work. Can someone help?
I am trying to automate the process of file read from a directory. The files older than 3 days are supposed to be archived. If they are in the three day limit, then they can be processed as a comand lien to a C program.
Here is the script:

#!/usr/bin/ksh
checkduration=259200 # 3 days in seconds
cur_timestamp=`date +%s` #current time in seconds

cd /home/roab/toc/; # change dir
for i in /home/roab/toc/*; do
if [ -f $i ]; then # if the file is there
filename=${i#/home/roab/toc};# get file name
last_mod=$(stat -c "%Y" ${i#/home/roab/toc}); # get last mod time of file in seconds last_mod=$(stat -c "%Y" filename)
#above line gathers file modified time in seconds from epoch

if [ $last_mod ]
then
time_diff=`expr $cur_timestamp - $last_mod`; #cal time difference 3 days or more
if [ $time_diff -lt $checkduration ] # file modified three days or less back
then
mv ${i#/home/roab/toc} /home/roab/old_data; #if more then move to a new folder
else
/root/home/source/programs/abc.out filename; # if not call c program with filename as argument
cat filename>>log; #append this file name to log sheet
fi
fi
fi

the following are the errors:
stat: cannot stat `/22018-000181': No such file or directory
stat: cannot stat `/22018-000182': No such file or directory
stat: cannot stat `/22018-000183': No such file or directory
stat: cannot stat `/22018-000184': No such file or directory

stat: cannot stat `/22018-000186': No such file or directory
stat: cannot stat `/22018-000187': No such file or directory

Please help.
