Top Forums Shell Programming and Scripting sed, grep, awk, regex -- extracting a matched substring from a file/string Post 302074402 by vino on Tuesday 23rd of May 2006 07:58:39 AM

How about

Code:
sed -n -e "s_.*a href=.\([^\"]*[Tt][Aa][Ll][Kk][.]*[Bb][Aa][Cc][Kk].[Mm][Pp]3\).*_\1_p"

It says, capture everything within the quotes until you encounter .mp3 or .MP3 or anything similiar. It should handle "talk back", "talkback" and is case insensitive.

NORMALIZE-MP3(1)					      General Commands Manual						  NORMALIZE-MP3(1)

NAME
normalize-mp3 - adjust levels of mp3 or ogg files by running normalize-audio(1), then re-encoding SYNOPSIS
normalize-mp3 [OPTION]... [FILE]... normalize-ogg [OPTION]... [FILE]... DESCRIPTION
Normalize volume of mp3 or ogg files by decoding, running normalize, and re-encoding. This requires as much extra disk space as the largest mp3 or ogg file, decoded. Note that for batch and mix mode, all files must be decoded, so there must be enough disk space for the decoded copies of all specified mp3 and ogg files. --ogg Convert files to OGG, regardless of original format --mp3 Convert files to MP3, regardless of original format --bitrate BR Set bitrate of re-encoded file (default 128) --tmpdir TMP Put temporary WAV files in temp directory TMP --notags Do not copy ID3 or OGG tags to the output file The following four options may be used to set the encoder and decoder commands for mp3 and ogg vorbis. %m is expanded to the name of the mp3 or vorbis file, %w expands to the name of the temporary WAV file, and %b expands to the bitrate, as specified by the --bitrate option. Run normalize-mp3 with no arguments to see the default values. --mp3encode=X mp3 encoder --mp3decode=X mp3 decoder --oggencode=X ogg vorbis encoder --oggdecode=X ogg vorbis decoder -h Display this help and exit. -V Display version information and exit. These arguments are passed as arguments to normalize-audio. Run "normalize-audio --help" for more info. -a AMP -g ADJ -n -T THR -b -m -v -q REPORTING BUGS Report bugs to <chrisvaill@gmail.com>.
