Hello fellow scripters!
Hello,
I've come across weird regex like this: (.{4}).(.{21}).(.{3})..(.{3}).
(.{10}).(.{9}).
Has anyone any idea about the syntax of these regex? Thank you for
your help.
The period (.) matches any character except the newline character unless the
/s option is used and then it matches any character including the newline
character.
So that expression matches 4 characters and stores them in $1 then matches 1
character then matches 21 characters and stores them in $2 then matches 1
character then matches 3 characters and stores them in $3 then matches 2
characters then matches 3 characters and stores them in $4 then matches 1
character then matches 10 characters and stores them in $5 then matches 1
character then matches 9 characters and stores them in $6 then matches 1
character.
