Any answer for this question?

radoulov · #7 (**permalink**) 05-16-2008

Code:

perl -nle'm|([^/]*)$| and print $1' input
perl -nle'm|([^/]*)/[^/]*$| and print $1' input
perl -nle'm|/([^/]*/){2}(([^/]*/){2}[^/]*)| and print $2' input

Or just:

Code:

perl -F\/ -anle'print $F[-1]' input
perl -F\/ -anle'print $F[-2]' input
perl -F\/ -anle'print join "/", @F[3..5]' input

Thanks Radoulov
I was looking for only simple RE string not perl. something like:
[^\n\r]*/([^/\n\r]*)/[^/\n\r]*

What's the reason? What are you trying to achieve?

I'm given a text files & i'm required to extract specific fields or directories from each line in the file and it must be extracted using regular expressions.
