Programming :: Extract A Substring Using Regular Expression With SED
May 7, 2011I've spent most of the evening browsing the web, trying many things I've found on various forums, but nothing seems to work.
I have a test.txt file containing many lines like the following ones :
...
<insert_random_text>228.00 €<insert_more_random_text>
<insert_random_text>17.50 €<insert_more_random_text>
<insert_random_text>1238.13 €<insert_more_random_text>
...
And I want to extract :
...
228.00
17.50
1238.13
...
There is always one occurrence of € in each line. I want the numeric value that precedes this € occurrence. The random text (before and after) may contain numbers too, so the € may be important to parse, in order to correctly identify the number to return. The last character that precedes the number to extract is always a ">" (coming from an HTML tag).

General :: Using 'dd' To Extract Files From DataPlow FS?
Jun 19, 2010I haven't been to this site in quite a while, since it changed from LNO in fact. Good to see this place is still around, albeit under a newer name.
I'll get on with the problem. I've got a Netgear SC101T that I was using to store my files on. Some of you may know it uses the DataPlow SAN file system. It worked fine until I installed a firmware update which, for some reason, broke the mirror array. I've hated this POS ever since and want to pull the data from the drives and toss the box. The problem is, linux doesn't have support for this particular file system scheme.
What I'm wondering is, how does 'dd' work, in regards to keeping the file system. Does it simply copy files and disregards the structure, or does it make an exact copy, DataPlow FS and all? Anyone else ran into this conundrum?

General :: Extract The First Word Following A String?
Aug 22, 2010I need a bash script that can read a file, say example.txt search for the string "This is my example string" and save whatever word/number comes immediately after it to a variable, var.
Example:
blah blah
blah This is my example string extracthere is a very nice word.
blah blah
There are two constraints:1. This needs to assume as little as possible about the nature of the known string "This is my example string" and the word that follows it. I am trying to keep my code adaptable.2. Speed is valuable. This shell will be executed dozens if not hundreds of times so speed is very desirable. I thought I read that some commands are faster than others.

General :: Any Way To Diagnose Tar When Files Missing On Extract?
Aug 3, 2010I have tar files where I archive about 250 files, each about 80 Mb, without compression. In a few cases tar is only returning some of the files. For example, when doing an extract of the file using:
tar -xvf 356.tar
I got only 103 files, when it should return 255 files, but tar does not give me an error. Furthermore, the tar archive is 15.8 Gb while the extracted folder is just 6.4 Gb. The tar files were created using:
tar -cvf 356.tar 356
where 356 is the name of the folder. All the steps where done in the same machines, under Ubuntu 6 and newer. Any ideas if there is a way to recover the files that are not being extracted?
