I/O error, dev sda, sector 404664
failed command: READ DMA

The dmesg output is huge, how can I grep only the necessary?

Sometimes we DO need a ready made solution, and Akshay was much more helpful than anyone else in this thread.

It's amazing how some people think they know what's best for everyone.

Thank you...

I have no idea where to start.

I could do a big shellscript to do it, but I believe there's something much simpler that I'm missing.

I have a file "fruits" and one "colors"

File "colors" contains:

The problem was only that my file had CRLF terminators. Using fromdos solved it.

I want to add the character "<" to the end of each line of input using the & function in SED.

Something like:
sed 's/.*/&\</'

It's important to use the &, not another method, because I want...

I tried this option but it didn't work. It seems that this delay only applies when Wget receives an error.

I have a list of URLs that I need to download in a file.

I know I can use the -i option to load the URLs from the file, but how can I make Wget wait a couple secs between each URL download?

I have a list like this:

todu
todo
tofe
tafo

I want to grep only the lines where the 2nd and the 4th character are the same.
In this case I would get only "todo".

Thanks.

Thanks, this is almost good.

The problem is that it discards Country specific domains like
"bol.com.br" for example.
