grep for searching

[ejonesss]

i was wondering what is the grep i would need to find all occurrences of a word that begins with

ftp://ftp.scene.org/pub/demos/artists/0xf/drunkchessboard.zip


for example i want to find all lines who has file of “.zip" and begins with “d"

drunkchessboard.zip

i got the finding .zip part ok that is how i extracted all the zips from a massive 600000 line list

now the tricky part is detecting the “/d” part

I’m on my phone so I can’t test it but:

d\w+\.zip

Find:

(?<=/)(?:d([^\s/]|\\\x20)*?\.zip)\b

Or commented:

(?x)                (?# Use multi-line and comments)
(?<=/)              (?# Look behind a slash not including it in the match)
(                   (?# Start of capture \1)
    d               (?# Literal 'd')
    (?:             (?# Start non capturing parentheses)
        [^\s/]      (?# NOT [whitespace or slash] character)
    |               (?# or)
        \\\x20      (?# Backslash escaped space)
    )               (?# End non capturing parentheses)
    *?              (?# Match 0 or more greedily)
    \.              (?# Literal '.')
    zip             (?# Literal 'zip')
)                   (?# End of capture \1)
\b                  (?# Word boundary)

Should match:
ftp://ftp.scene.org/pub/demos/artists/0xf/drunkchessboard.zip
ftp://ftp.scene.org/pub/demos/artists/0xf/d.zip
"ftp://ftp.scene.org/pub/demos/artists/0xf/d0xf+==&amp;.zip"
/path/to/unicode/files/d你好.zip
/path/to/document\ with_escaped_space.zip

Should NOT match:
ftp://ftp.scene.org/pub/demos/artists/0xf/d.zipped      -- Wrong extension.
/path/to/document with_unescaped_space.zip              -- Has unescaped space.
document.zip                                            -- Missing /.
