scripts help

[Sir T S S]

hi ,
how to do a simple scripts when the scripts check for the today file based on today date, if exist and size > 0 then perform the processing.

any help is appreciated.

with the command find . -ctime -1 you can get the files which have been modified the last 24 hours .

You can also test if a file exists or not. Example:


if [ -r /etc/rc.config.d/samba ]
then . /etc/rc.config.d/samba
fi

Also you can get the size of a file:

ll | awk '{ print $5 }'

An addition to previous reply.
"find . -ctime 1" lists files that has their status changed
in last 24 hrs. To see file that were modified in last 24
hrs, use "-mtime" instead of ctime.

One key thing is, last 24hr is not necessarily today.
So you might want to get today's date (by using
date command) and search (using grep) for today's
date from the find output. This also handles files
created on same date one or more years back.

Try the script as,

for file in `find . ! -name . -ctime -1`
do
if [[ $(ls -s $file | awk '{ print $1 }') -gt 0 ]]
then
# operation $file
echo $file
fi
done

HTH.
