I tried extracting this pattern using grep but it did not work.
What I have is a file which has contents like this:
Now what I want to do is to extract all http, https, and file patterns or lines and get rid of IMG, My Yahoo!, Yahoo! News etc. This means my final output should like this:
Doing:
extracts lines containing "http". But I want to extract all the three patterns by somehow nesting grep. I even tried this:
But it did not work. I am using Linux with Bash.
Sample input:

System
Networking in Nature

unzip
UNZIP(1) BSD General Commands Manual UNZIP(1)NAME
unzip -- extract files from a ZIP archive
SYNOPSIS
unzip [-aCcfjLlnopqtuv] [-d dir] zipfile
DESCRIPTION
The following options are available:
-a When extracting a text file, convert DOS-style line endings to Unix-style line endings.
-C Match file names case-insensitively.
-c Extract to stdout/screen. When extracting files from the zipfile, they are written to stdout. This is similar to -p, but does
not suppress normal output.
-d dir Extract files into the specified directory rather than the current directory.
-f Update existing. Extract only files from the zipfile if a file with the same name already exists on disk and is older than the
former. Otherwise, the file is silently skipped.
-j Ignore directories stored in the zipfile; instead, extract all files directly into the extraction directory.
-L Convert the names of the extracted files and directories to lowercase.
-l List, rather than extract, the contents of the zipfile.
-n No overwrite. When extracting a file from the zipfile, if a file with the same name already exists on disk, the file is silently
skipped.
-o Overwrite. When extracting a file from the zipfile, if a file with the same name already exists on disk, the existing file is
replaced with the file from the zipfile.
-p Extract to stdout. When extracting files from the zipfile, they are written to stdout. The normal output is suppressed as if -q
was specified.
-q Quiet: print less information while extracting.
-t Test: do not extract anything, but verify the checksum of every file in the archive.
-u Update. When extracting a file from the zipfile, if a file with the same name already exists on disk, the existing file is
replaced with the file from the zipfile if and only if the latter is newer than the former. Otherwise, the file is silently
skipped.
-v List verbosely, rather than extract, the contents of the zipfile. This differs from -l by using the long listing. Note that
most of the data is currently fake and does not reflect the content of the archive.
-x pattern Exclude files matching the pattern pattern.
-Z mode Emulate zipinfo(1L) mode. Enabling zipinfo(1L) mode changes the way in which additional arguments are parsed. Currently only
zipinfo(1L) mode 1 is supported, which lists the file names one per line.
Note that only one of -n, -o, and -u may be specified. If specified filename is "-", then data is read from stdin.
ENVIRONMENT
If the UNZIP_DEBUG environment variable is defined, the -q command-line option has no effect, and additional debugging information will be
printed to stderr.
COMPATIBILITY
The unzip utility aims to be sufficiently compatible with other implementations to serve as a drop-in replacement in the context of the
ports(7) system. No attempt has been made to replicate functionality which is not required for that purpose.
For compatibility reasons, command-line options will be recognized if they are listed not only before but also after the name of the zipfile.
Normally, the -a option should only affect files which are marked as text files in the zipfile's central directory. Since the archive(3)
library reads zipfiles sequentially, and does not use the central directory, that information is not available to the unzip utility.
Instead, the unzip utility will assume that a file is a text file if no non-ASCII characters are present within the first block of data
decompressed for that file. If non-ASCII characters appear in subsequent blocks of data, a warning will be issued.
The unzip utility is only able to process ZIP archives handled by libarchive(3). Depending on the installed version of libarchive, this may
or may not include self-extracting archives.

The unzip utility appeared in FreeBSD 8.0.
