Is there a simple way of modifying a file?

[Andreas Sinz]

Modifying in the sense of changing line by line?

[mike_shysh]

yeah, I want to remove prefix of the string in each line

[Andreas Sinz]

@mike_shysh then I'd go with https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.io/java.io.-file/read-lines.html, remove the prefix and write the lines back into the file

[mike_shysh]

seems to me it requires a temporary file
