Auto checking a file for growth
- Thread starter icu812
- Start date
icu812,
Crudely, you could do.....
#!/bin/ksh
size=`ls -l /<path to file> |awk '{print $5}'`
if [ ${size} != "0" ];
then
echo "size is not zero"
else
echo "size is zero"
fi
Run this from the cron every 5 mins or whatever and replace the echo "size is not zero" with the command you wish to run
Hope that helps

The -s option is "file has a size greater than zero".
Put in your script to page you if return code is anything other than 1.
[ -s filename ];print $?
Your return code $? should be 1 if it is still at zero byte size. Your return code $? will be 0 if it has grown.
if [ -s filename ]
then
mail -s "filename has grown" you@company.com < filename
else
exit
This will include the contents of filename in your email text. Remember, amateurs built the Ark, professionals built the Titanic.

If you wanted something a bit more instant, then you could knock up a script ( say, myscript ) which reads from stdinput, and mails you a message as soon as it reads a line of input.
Then all you'd need to do is run a background task similar to the following:
tail -f logfilename | myscript
Something else to consider

The find command could be used as well. As in:
find {PATH} -name {FILE} -size +0 -exec {NOTIFY} \;
which I believe will only search the PATH for the FILE and will only run the NOTIFY command when the size is greater than zero. You could put that in a cron script described by PSD above. The benefits that find has over ls | awk are only a single command instead of two, and it would use less resources (I may be wrong - but calling awk for a simple one line check is wasteful).
Anyhow, I hope you find your answer.
