read num > ./st/file1
i did not get any error but still the num value is not sotred in file1

can u plz help me with this !!

no one can help me !!

The code is correct if you're using bash.

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.
