the good:

Server: Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu5.4 with Suhosin-Patch

the bad:

Server: Microsoft-IIS/6.0

and the ugly:

Server: Apache/2.2.10 (Win32) mod_ssl/2.2.10 OpenSSL/0.9.8i PHP/5.2.6

This is the result of a several week venture without X. I found myself totally happy without X (and by extension without flash) and was able to do just about anything but watch YouTube videos... so this a the solution I came up with for that. I am sure this can be done better but this does indeed work... and tends to work far better than YouTube's ghetto proprietary flash player ;-)

Replace $i with any YouTube ID you want and this will scrape the site for the _real_ URL to the full quality .FLV file on Youtube's server and will then will hand that over to mplayer (or vlc or whatever you want) to be streamed.

In some browsers you can replace $i with just a % or put this in a shell script so all YouTube IDs can be handed directly off to your media player of choice for true streaming without the need for Flash or a downloader like clive. (I do however fully recommend clive if you wish to archive videos instead of streaming them)

If any interest is shown I would be more than happy to provide similar commands for other sites. Most streaming flash players use similar logic to YouTube.

Edit: 05/03/2011 -

Updated line to work with current YouTube. It could be a lot prettier but I will probably follow up with another update when I figure out how to get rid of that pesky Grep. Sed should take that syntax... but it doesn't.

Original (no longer working) command:

mplayer -fs $(echo "http://youtube.com/get_video.php?$(curl -s $youtube_url | sed -n "/watch_fullscreen/s;.*\(video_id.\+\)&title.*;\1;p")")

Suppose you made a backup of your hard disk with dd:

dd if=/dev/sda of=/mnt/disk/backup.img

This command enables you to mount a partition from inside this image, so you can access your files directly.

Substitute PARTITION=1 with the number of the partition you want to mount (returned from sfdisk -d yourfile.img).

The large context number (-C 1000) is a bit of a hack, but in most of my use cases, it makes sure I'll see the whole log output.

grep 'HOME.*' data.txt | awk '{print $2}' | awk '{FS="/"}{print $NF}'

OR

awk '/HOME/ {print $2}' data.txt | awk -F'/' '{print $NF}'

In this example, we are having a text file that is having several entries like:

---

c1 c2 c3 c4

this is some data

HOME /dir1/dir2/.../dirN/somefile1.xml

HOME /dir1/dir2/somefile2.xml

some more data

---

for lines starting with HOME, we are extracting the second field that is a 'file path with file name', and from that we need to get the filename only and ignore the slash delimited path.

The output would be:

somefile1.xml

somefile2.xml

(In case you give a -ive - pls give the reasons as well and enlighten the souls :-) )

exclude-dir option requires grep 2.5.3

Explanation:

* The date command evaluated to today's date with blank padded on the left if single digit

* The grep command search and highlight today's date

* The --before-context and --after-context flags displays up to 6 lines before and after the line containing today's date; thus completes the calendar.

I have tested this command on Mac OS X Leopard and Xubuntu 8.10

recursively traverse the directory structure from . down, look for string "oldstring" in all files, and replace it with "newstring", wherever found

also:

This command kills all processes with 'SomeCommand' in the process name. There are other more elegant ways to extract the process names from ps but they are hard to remember and not portable across platforms. Use this command with caution as you could accidentally kill other matching processes!

xargs is particularly handy in this case because it makes it easy to feed the process IDs to kill and it also ensures that you don't try to feed too many PIDs to kill at once and overflow the command-line buffer.

Note that if you are attempting to kill many thousands of runaway processes at once you should use 'kill -9'. Otherwise the system will try to bring each process into memory before killing it and you could run out of memory. Typically when you want to kill many processes at once it is because you are already in a low memory situation so if you don't 'kill -9' you will make things worse

These part of the command:

svn status | grep '^\?' => find new file or directory on working copy

sed -e 's/^\?//g' => remove "^" character on the first character of file name

xargs svn add => add file to subversion repository

You can modify above command to other circumtances, like revert addition files or commit files that have been modified. ^_^

Output: Version 3.2-0 (for example if you type # aptitude show bash | grep Vers

Depends on the language of your distribution, because the name of the word "Version" in other languages may be different.

This command will list a CSV list of infected files detected by clamav through squidclamav redirector.

Show only the subdirectories in the current directory. In the example above, /lib has 135 files and directories. With this command, the 9 dirs jump out.

rpm, sometimes, is not wildcard friendly. To search files installed from package this could be useful.

change PACKAGENAME to any package do you want to search

This command gives a model information of a computer. Also useful in determining the host is a VM machine or actual physical machine.

Useful in scripts while you just need an IP address in a variable.

I've had this as mute.sh in my ~/bin/ for some time.

greps for search word in directory and below (defaults to cd).

-i case insensitive

-n shows line number

-H shows file name

Note that the file at the given path will have the contents of the (still) deleted file, but it is a new file with a new node number; in other words, this restores the data, but it does not actually "undelete" the old file.

I posted a function declaration encapsulating this functionality to http://www.reddit.com/r/programming/comments/7yx6f/how_to_undelete_any_open_deleted_file_in_linux/c07sqwe (please excuse the crap formatting).
