txt文件删除网址到最后一个“ /”以获取文件

Question

I have txt file contaning one url per row each url as:

://url/files.php?file=parent/children/file.pdf
://url/files.php?file=parent/children2/childrenofchildren2/file2.txt
......etc

I need help to cut everythink before last / in a row. That is what I used in notepad++ regex mode (it doesnt work):

^.+[/](.*)$

To get:

file.pdf
file2.txt

But I am open to all waysof solving.

Answer 1

Replace your line from left including / by nothing:

sed 's/.*\///' file

or

sed 's|.*/||' file

Output:

file.pdf
file2.txt

Answer 2

This solution may be more complicated than it needs to be, but it works!

A purely regex-based approach could be as follows: (([^\\/])*)((\\n)|($))/g

Basically, it matches any number of non-newline and non \\ characters (([^\\/])*) and then stops when it either encounters a new line \\n or the end of the sequence $ . The global /g is also set, to allow it to match more than one instance!

I hope this helped!
