Do you need to exit vim?
Yes, i need to save the file content as well exit from current vi screen.

Quote:
But try to correct the workflow first and use other tools not editors in scripts in such way...
Can you show the code, perhaps a better way can be devised to make entire processing.
Considered the below sample codes did same as the real environment.
In real script i didn't have permission to change the file, so i am not able to change the workflow.
The script do lot of checks and finally create file by using vi command.
Currently the end user must type :wq! to save and exit the file, So the script move on next iteration.
I expected to find some solution to send keys to close that file and complete the script without manual intervention

Code:
#!/usr/bin/perl

### script name as test.pl and we doesn't have permission to modify that file.
### considered file1.txt is new file and it default text populated 
system("vi file1.txt");
### User manually save the file by using of :wq!. so it moves to next instruction in script

### considered file2.txt is new file and it default text populated 
system("vi file2.txt");
### User manually save the file by using of :wq!. so it moves to next instruction in script


### iteration going on Nth term
### considered file_n.txt is new file and it default text populated 
system("vi file_n.txt");
### User manually save the file by using of :wq!
