Once, when generating commands for configuring the OLT, I needed to take part of the configuration of a working device and remove 2 characters from the end of each line.
As always, thanks to Notepad++, such tasks are done very quickly. Open the search with CTRL+H, select “Regular Expressions” in the Search Mode at the bottom, and enter the following in the Find field:
..$
Leave the “Replace with” field empty and click “Replace all”.
The number of dots indicates the number of characters, and $ indicates the end of the line.
