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.

mrename - program to rename files
SYNOPSIS
mrename 'pattern' prefix [option]
DESCRIPTION
This manual page documents briefly the mrename command. This manual page was written for the Debian GNU/Linux distribution because the
original program does not have a manual page.
mrename is a tool for easy and automatic renaming of many files. The 'pattern' is the pattern to search files to rename (quoted to avoid
that bash resolve it), and prefix is the prefix that will be added to the name of each file. The two alternative options for copying or
moving files in the new name are explained below. All parameters are needed, and you have to stay and launch the script in the same direc-
tory of the files to be renamed. The program should be able to write in this directory.
OPTIONS
There are only the following three options.
-c The option -c will copy each file with the new filename.
-m The option -m will move each file in the new filename.
-h Display help.
EXAMPLE
If you have a directory with two jpeg images prof.jpg and forp.jpg and you want to add them a prefix like item0, item1 etc.. (that is
item0prof.jpg, item1forp.jpg etc..) do this:
cd /path/to/the/images
mrename '*.jpg' item -c
to copy each matching file into another with the new name
mrename '*.jpg' item -m
to rename each file without keeping a copy with the previous name
