The option _netdev should be added to the /etc/fstab lines.
Mount will then wait until network is running before mounting.

I had problems writing/saving remote files through ex emacs but by passing the direct_io in the -o switch it works.

“curlftpfs -o allow_other,direct_io ftp://...”

Have you ever piped output through firefox to a file? Would use lynx but its an unsupported browser for the webpage I’m trying to copy down.

Comment on sometimes, grep alone is enough to do the task by doobiest

I dont think there’s anything wrong with cat file|grep “search term” under certain circumstances. If you’re going to continually grep the same file for various things it’s easier to cat it to a grep, it’s easier because you can change the search string faster as it’s at the end of the line instead of in the middle.

If I was going to grep various files for one search term I would use grep “search term” filename, because now the filename is at the end. It’s all about context and the type of repetition.

Thanks! I was searching how to get images from a website, which haven’t got correct extensions… Using urllib, re and writing a binary file gives me quite useful effect. :)

Comment on open multiple files in tabs, vim 7 can do that. by graywh

Actually, if you just “:set hidden” you can change buffers without saving first. There’s no need to use one buffer per tabpage.

That is an awesome tip. I was going to write an Perl script to extract stuff like this, but figure I should check Grep’s awesome utility first. Thanks!!
