Shell Programming and Scripting

In my script, I am creating a file ----> then writting one line (i.e. Timestamp) ----> then FTP'ing. The same script can be executed by many other users.
While other users executing this script, they couldn't Over write this one line (i.e. Timestamp)

My expectation
So I wanted to create a file with full permission(_rwxrwxrwx). Not by chmod.

Code

Code:

dt=`date +%m_%d_%y`
Tablename=$1

Filename=$Tablename"_"$dt.dmp
FlgFile=$Tablename.flg
 
echo $Filename > $FlgFile
chmod 777 $FlgFile

Error
When other user executing this script they are getting an error chmod: changing permissions of .FlgFile. "Operation not permitted"

Thanks in advance

You can set umask 000 for the dir where the file will be created.

If your colleagues and you are in same unix group, umask 002 is enough.
