  • Filepath column data: basename

    From Sarat Sreepathi@21:1/5 to All on Fri Nov 20 16:18:07 2020
    Hello:

    I have a data file where one of the columns contains full path names. Is there a trick to getting a basename from that field? Any builtins for other transformations on that field?

    Appreciate any pointers.
    Thanks,
    Sarat.

    Recursion: ;)

    basen(fullp) = (a = strstrt(fullp,'\'), a == 0 ? fullp : basen( substr(fullp,a+1,strlen(fullp) ) ) )

    pr basen('helo')
    pr basen('helo\halo')
    pr basen('helo\halo\holo')

    In the same way you can delete (possibly multiple) .extensions from
    the filename.

    Can you use a function?
    e.g. f=system("basename ".fullpath)
