The code is correct if you're using bash.
# 4  
i'm using sh command to run my script...

If the file is exists before,,, and im trying to overwrite it , the code is still valid or i have to change something !!!

because i used the same code in another place trying to write a value in a file just created and it works fine..

i appreciate your reply 'redoubtable'

Generally sh is just a symbolic link to your real shell. In my case /bin/sh points to bash.

Show me where your /bin/sh points to (ls -l /bin/sh)

here u go

I'm afraid that didn't show the actual shell you're using. Which OS/distro are you running?

Possible workarounds are installing bash or revising if the file where you're executing that code has something else other than that code. There's no ':' in your code that could provoke that error.
