linux - Unable to run the cronjob in ubuntu 10.10 server, EC2 instance

I have a AWS EC2 instance with ubuntu 10.10 server.
I am trying to add a cron job to the list. But the cron job is not being executed.

I am actually uploading a particular file to aws s3 using s3cmd visit s3tools.org

What will be in the problem and also the solution.

Kindly help me out

Here is the bash script which has to be run

s3cmd put file-name s3://bucket_name/foder_name/file-name 

Here is the job

* * * * * bash /path/to/file.sh 

Answer

I was able to figure out the solution for this. The problem was I need to specify absolute path thats /usr/local/bin/s3cmd .
