linux Oops: I deleted an improtant file, can I undelete?
Linux does not offer a file undelete or unerase mechanism, especially in command line.
To undelete a really deleted file, it take guru’s work like in

This is the last thing one can do. However, if you take a few precautions, you may save yourself easily.
There is a small package named ptrash, which can be found at http://pjp.dgplug.org/tools/, and has been included in plenty of linux repos.
You can just try
yum install ptrash
to see if it is in your repo. If not, go to the website for a tar ball.
When installed, you may still forget using the nice new command “ptrash” for delete. To avoid this, you need to add a line in your ~/.bashrc as
alias rm=”echo file will be sent to \.trash\, use ptrash -d to purge.; ptrash -iv”
This will first remind you that your file will be moved to
~/.trash
folder, instead of being silently deleted.
In case you did it wrong, you can either move them back or use ptrash’s undelete option. The echo remind you that ptrash is the magic key.
Then log off and log in again to have a try. It also work on folders and wildcards.
For purging the ~/.trash folder, you can either setting up a cron job or leave it to yourself.
Enjoy.

Yet another thing to mention is that an online business administration training course is designed for learners to be able to easily proceed to bachelor’s degree courses. The Ninety credit education meets the lower bachelor college degree requirements and once you earn your associate of arts in BA online, you should have access to up to date technologies within this field. Several reasons why students need to get their associate degree in business is because they’re interested in the field and want to get the general instruction necessary previous to jumping to a bachelor diploma program. Thanks alot : ) for the tips you really provide in your blog.
What you posted made a ton of sense. However, what about this? what if you were to create a awesome headline? I mean, I don’t wish to tell you how to run your website, however suppose you added something that makes people want more? I mean Dao’s BLOG is kinda plain. You could glance at Yahoo’s home page and watch how they create post titles to get viewers to click. You might add a related video or a related pic or two to grab people interested about what you’ve written. In my opinion, it might make your blog a little bit more interesting.
Write more, thats all I have to say. Literally, it seems as though you relied on the video to make your point. You obviously know what youre talking about, why waste your intelligence on just posting videos to your blog when you could be giving us something enlightening to read?

Thanks for the points you have contributed here. Something important I would like to convey is that computer memory needs generally increase along with other advancements in the technological know-how. For instance, whenever new generations of processors are introduced to the market, there is certainly usually a similar increase in the type preferences of both laptop or computer memory plus hard drive space. This is because the software operated simply by these processors will inevitably increase in power to use the new technological know-how.

You need think about it. Despite the emails, the overwhelming evidence showing global warming is happening hasn’t changed.
“The e-mails do nothing to undermine the very strong scientific consensus . . . that tells us the Earth is warming, that warming is largely a result of human activity,” Jane Lubchenco, who heads the National Oceanic and Atmospheric Administration, told a House committee. She said that the e-mails don’t cover data from NOAA and NASA, whose independent climate records show dramatic warming.
I enjoyed your blog.
Great post!
