Hi,
I want separate the following string by "-" but unfortunately QRegExp doesn't match it
rg
(.*) - (.....) (.*)replace
\1 - \2 - \3string
KÜÇÜK OTOBÜS TAYO - S01E12 GEL ARKADAŞ OLALIMI expect to get
KÜÇÜK OTOBÜS TAYO - S01E12 - GEL ARKADAŞ OLALIMHi @mbnoimi,
The problem is that you don't have enough dots in the inner group - you have 5 dots, which matches 5 characters, but the input has 6 characters
S01E12.# Doesn't work... paul@paul-XPS-13-9343:~$ echo 'KÜÇÜK OTOBÜS TAYO - S01E12 GEL ARKADAŞ OLALIM' | sed -re 's/(.*) - (.....) (.*)/\1 - \2 - \3/' KÜÇÜK OTOBÜS TAYO - S01E12 GEL ARKADAŞ OLALIM # Add another '.' and all is good :) paul@paul-XPS-13-9343:~$ echo 'KÜÇÜK OTOBÜS TAYO - S01E12 GEL ARKADAŞ OLALIM' | sed -re 's/(.*) - (......) (.*)/\1 - \2 - \3/' KÜÇÜK OTOBÜS TAYO - S01E12 - GEL ARKADAŞ OLALIMCheers.

Indeed! Thanks

side notes:
- if you are using Qt5, do not use QRegExp, use QRegularExpression
.{6}is safer and faster than......- be careful with the greediness of
*operators here
