The command you have provided is incomplete. The `ne` operator requires a comparison value to be specified. For example, if you want to check if the exit status of the previous command is not equal to 0, you can use the following command:
```
if [ $? -ne 0 ]; then
echo "Previous command failed"
fi
```
This code checks if the exit status of the previous command (represented by `$?`) is not equal to 0, and if so, it prints a message indicating that the previous command failed.
