Can someone explain what this does step by step? I found this script on stackoverflow and want to customize it for personal use in downloading jpg images from a website.
Code:
# get all pages
curl 'http://domain.com/id/[1-151468]' -o '#1.html'
# get all images
grep -oh 'http://pics.domain.com/pics/original/.*jpg' *.html >urls.txt
# download all images
sort -u urls.txt | wget -i-
1. What I think the first like does is download the pages of domain with curl but what does the '#1.html' mean?
2. Why in .*jpg is the * after the '.'? Also what is this trying to do? I attempted altering this using a different website but there's an error grep: *.html: No such file or directory even though the first command is downloading the html files just fine.
3. I think the third option is just organizing the results and wget goes to the jpg's website and downloads the jpgs.

Not sure if this is the right place to be posting this. If not, let me know where it fits. I am running RedHat Linux 8.0. I've recently acquired a Sony Mavica digital camera.

Using Lynx, when I try to download a .rar, it confirms I want to download and its got it as an appication/rar file.
However, split archives that end in .r## (.r00, .r01 ...) are not recognized as an appication/rar file and it reads the file like a .txt or .html.
How can I fix this?
Thanks! (2 Replies)
Dear colleagues,
One of my friend have a problem with c code. While compiling a c program it displays a message like
"array type has incomplete element type". Any body can provide a solution for it.

PUZZLE-DIFF(1)PUZZLE-DIFF(1)NAME
puzzle-diff - Compare pictures with libpuzzle
SYNOPSIS
[-b <contrast barrier for cropping>] [-c] [-C <max cropping ratio>] [-e] [-E <similarity threshold>] [-h] [-H <max height>] [-l <lambdas>]
[-n <noise cutoff>] [-p <p ratio>] [-t] [-W <max width>] <file 1> <file 2>
DESCRIPTION
puzzle-diff compares two pictures and outputs the normalized distance.
Try puzzle-diff -h for more info.
EXAMPLES
Output distance between two images:
$ puzzle-diff pic-a-0.jpg pics-a-1.jpg

Compare two images, exit with 10 if they look the same, exit with 20 if they don't (may be useful for scripts):
$ puzzle-diff -e pic-a-0.jpg pics-a-1.jpg
$ echo $?
10
