  if [ $FILE1 -gt 0 ];
    then
    echo "File size has exceeded 1 GB" | mail -s "chetan.log" chetanp@moofwd.com  -c cchetans@moofwd.com
elif [ $FILE1 -gt 1073741 ];
then
rm -rf $CHETAN/chetan.log
  fi

fi

Mod Comment Please re-read the rules you agreed to when you opened your account on this forum.

Use CODE tags when you post sample input, sample output, and code segments.

Do not expect volunteers here to immediately solve all of your problems. Some of us have day jobs. Some of us like to sleep at night. Some of us have other things to do besides act as your personal problem solver. Demanding help twice in less than an hour after your initial post is a sure fire way to annoy volunteers who might be interested in helping you.

Instead of showing us a script and saying it doesn't work, tell us what the script is supposed to do, tell us what the script is doing (including showing us the input data it is processing), and tell us what the script is doing on your system showing us any output (standard output, files or mail messages created, and diagnostic messages produced), and show us the output you were hoping to get.

You have shown us that you're using bash as your shell. (Thank you.) It frequently also helps to know what OS you're using. Options and limits vary from system to system; if we know what system you're using, we have a much better chance of giving you advice that will work correctly in your environment.

Be patient bro, this is not a chat room Smilie
I think you want something like this (untested)
Code:
#!/bin/bash

#moofwd-rt.log check
CHETAN='/Users/ajit'

if [ -a $CHETAN/chetan.log ];
then # file exists
    FILE1=$(du -ks $CHETAN/chetan.log | awk '{print $1}') # get file size
    if [ $FILE1 -gt 1073741 ]; # file greater than ~1 GB
    then # send mail + delete file
    echo "File size has exceeded 1 GB" | mail -s "chetan.log" chetanp@moofwd.com -c cchetans@moofwd.com
    rm -rf $CHETAN/chetan.log
    else 
    echo "File size is under 1 GB"
    fi
else # file does not exist
    echo "chetan.log not found"
fi

Try this and let me know if it does what it should do
Code:
#!/bin/bash

#moofwd-rt.log check
CHETAN='/Users/ajit'

if [ -a $CHETAN/chetan.log ];
then # file exists
    FILE1=$(du -ks $CHETAN/chetan.log | awk '{print $1}') # get file size in K

    if [ $FILE1 -ge 2097152 ]; # file size is greater than or equal to 2 GB
    then # delete
        echo "File size >= 2 GB, deleting file"
        rm -rf $CHETAN/chetan.log
    elif [ $FILE1 -gt 1048576 ]; # file size is greater than 1 GB
    then # send mail
        echo "File size has exceeded 1 GB" | mail -s "chetan.log" chetanp@moofwd.com -c cchetans@moofwd.com
    else # file size did not reach 1 GB
        echo "File size is under 1 GB"
    fi

else # file does not exist
    echo "chetan.log not found"
fi

First up all Thank you.... I tried this



Code:
#!/bin/bash

#moofwd-rt.log check
CHETAN='/Users/ajit'

if [ -a $CHETAN/chetan.log ];
then # file exists
    FILE1=$(du -ks $CHETAN/chetan.log | awk '{print $1}') # get file size in K

    if [ $FILE1 -ge 2097152 ]; # file size is greater than or equal to 2 GB
    then # delete
        echo "File size >= 2 GB, deleting file"
        rm -rf $CHETAN/chetan.log
    elif [ $FILE1 -gt 1048576 ]; # file size is greater than 1 GB
    then # send mail
        echo "File size has exceeded 1 GB" | mail -s "chetan.log" chetanp@moofwd.com -c cchetans@moofwd.com
   # else # file size did not reach 1 GB
   # echo "File size is under 1 GB"
    fi

else # file does not exist
    echo "chetan.log not found"
fi



But no luck


I only want

1. Files size 1gb >> Send Email Notification
2. Files Size grater than 2 GB >> DELTE FIles
3. file does not exist

I only want this I disabled the above code as

# else # file size did not reach 1 GB
# echo "File size is under 1 GB"

I do not need this...Also tried with above code but e-mails notification are not getting...

Tahnk you in Advancee...plzzz

You haven't said what OS you're using. On some systems test -a file tests for the existence of any file named file; on others it is a binary and operator between two expressions. It would be safer to use test -e file to test for the existence of a file named file or test -f file to test whether or not file exists and is a regular file.

Removing a file won't necessarily free up any space on your file system. If there is a process that is keeping the log file open while writing to it over an extended period of time, the process writing to the log may continue writing to the old file that no longer has a name in the file system. (So, any messages written to the log will be lost forever. And, if you create a new log file with the same name, it may remain empty while messages continue to be written to the old, inaccessible file.) It would be safer to copy /dev/null to the log than to remove it if you want to free up space that had been allocated. But, you really need to be sure that any process that had the log open closes the log file before you remove or truncate it to be sure that future messages written to the log will not be written at a starting offset of 2+Gb.

Your file size calculations are assuming a certain filesystem type (such as with direct blocks, indirect blocks, and double indirect blocks). You might want to key off of the file size (from the stat or ls utilities) rather than the number of blocks allocated (from the du utility). The code junior-helper suggested assumes that all blocks reported by du contain data (i.e., there are no indirect blocks allocated). Whether this does what you want is again filesystem dependent.

Is the current file size greater than 1 GB Smilie Maybe the current file size is less than 1 GB right now...

Run this command on the command line (not in script!) and see if it will work:
Code:
echo "File size has exceeded 1 GB" | mail -s "chetan.log" chetanp@moofwd.com -c cchetans@moofwd.com
