How can I use regular expressions in Textpad to remove anything, line by
line, after specified characters?
Suppose I have the following text in Textpad:
kwejkewrjl:ksajdlakj
e833ekjh:skdjkahak
2098e123809:ksjdkas
dkjwhfdkjqhio:skjddksjal
98a09asfdsaok:kwqjeo912ui
I would like to remove all characters from each line that occur after the
colon. The new text should be:
kwejkewrjl:
e833ekjh:
2098e123809:
dkjwhfdkjqhio:
98a09asfdsaok:
