Need help, Cant access html file from lynx, even though its readable by other
commands.
$ ls -l "test bay#, wwid"
-rw-r--r--+ 1 test Users 50999 Nov 17 03:22 test bay#, wwid
$ file "test bay#, wwid"
test bay#, wwid: HTML document, ASCII text, with very long lines
$ head -2 "test bay#, wwid"
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
>
$ lynx -dump "test bay#, wwid"
Can't Access `file://localhost/cygdrive/e/test%20bay#,%20wwid'
Alert!: Unable to access document.
lynx: Can't access startfile
Played around and found that if i create any file with "#, " lynx cant
understand it.
Its on win-7; do not know if there is any other special character that lynx
has problem with.
Can't even check in the script for a valid filename since shell commands
recognize this file well.
Appreciate your help.

Few more tests: seems lynx dont like #
$ mv "test bay#, wwid" "test # abc"
$ lynx -dump "test # abc"
Can't Access `file://localhost/cygdrive/e/test%20#%20abc'
Alert!: Unable to access document.
lynx: Can't access startfile
$ mv "test # abc" "test# a"
$ lynx -dump "test# a"
Looking up test
Making HTTP connection to test
Alert!: Unable to connect to remote host. <<
lynx: Can't access startfile http://test/#%20a
$ head -1 "test# a"
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"

So, just changing the filename gives completely different results.

A "#" marks a separator in a URL between the URI part and the anchor within
the page to load up the display at. I think lynx is applying the same syntax
to local file URLs; for example, if you have a local file "index.html", you
can append any arbitrary # anchor to it:

So I think it's a limitation of the URL format that it's ambiguous between a
filename with an actual # in it and a filename followed by "#" and an anchor,
and there's probably not much lynx can do about it. Your best bet, if you
absolutely have to use lynx on files with hash signs in their names, would be
to use lynx's -stdin option and redirect the input from the file, so that lynx
doesn't ever see the filename at all:
> $ lynx -dump "index.html # abc"
>
> Can't Access `file://localhost/tmp/lynx/index.html%20#%20abc'

Apart from that, all non-graphical characters in an URL are converted to
the %xx syntax. Therefore, the URL "test # abc" is converted to
"file://[$PWD]/test%20#%20abc" *before* trying to find the file. So
lynx tries to access the file "test%20#%20abc" in the current directory,
which obviously doesn't exist.
