Question

I have text that start with lines like:

[1] some text
[2] another text
[56] third

I need to remove the square brackets (only at the beginning of the lines) and leave the number and text as is, like:

1 some text
2 another text
56 third

I use notepad++

Answer 1

Search for

^\[(\d+)\]

and replace with

\1

• ^ is an anchor for the start of the row

• You have to escape the square brackets, since they have a special meaning in regex

• \d+ is at least one digit

• Because of the brackets around \d+, the number is stored in \1 so you need \1 as replace text.
