PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc. This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root filesystem, making files accessible somewhere else in the filesystem hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can use PRoot as a generic Linux process instrumentation engine thanks to its extension mechanism, see CARE for an example. Technically PRoot relies on ptrace, an unprivileged system-call available in every Linux kernel.

Securely stream a file from a remote server (and save it locally).

Useful if you're impatient and want to watch a movie immediately and download it at the same time without using extra bandwidth.

This is an extension of snipertyler's idea.

Note: This command uses an encrypted connection, unlike the original.

cat file | paste -s -d'%' - | sed 's/\(^\|$\)/"/g;s/%/","/g'
while true; do date; (curl -s -o 1.html http://www.biglion.ru/deals/ebay-80/ &); sleep 5; cat 1.html | grep "&#1082;&#1091;&#1087;&#1086;&#1085;&#1086;&#1074;" | awk -F"<div>" '{print $2}' | awk -F"<span>" '{print $1}'; done

Processes biglion quantity of sold ebay coupons/bonus codes, so you can know approximate count of users who buyed the coupons and when sales are come up again.

You can change sleep parameter so script will work slowly or faster (default is 5 seconds).

Additional requirements: curl

Standart tools used: awk, date, cat, grep (bash)

"find ./ ..." could be replaced with "find $PWD ..." to display absolute path instead of relative path.

This command is used to verify a sha256sum-formatted file hash list on IBM AIX or any other UNIX-like OS that has openssl but doesn't have sha256sum by default. Steps:

1: Save to the filesystem a script that:

A: Receives as arguments the two parts of one line of a sha256sum listing

B: Feeds a file into openssl on SHA256 standard input hash calculation mode, and saves the result

C: Compares the calculated hash against the one received as argument

D: Outputs the result in a sha256sum-like format

2: Make the script runnable

3: Feed the sha256sum listing to xargs, running the aforementioned script and passing 2 arguments at a time

Exactly the same effect with 3 less characters ;-) (Removes all files/filesystems of a harddisk. It removes EVERYTHING of your hard disk. Be careful when to select a device.)

You can press Ctrl + C after few seconds

The first sort is necessary for ips in a list to be actually unique.

Useful for when you download movies split into < 700mb parts.

mencoder is generally included with mplayer.

MacPorts:

sudo port install mplayer

After splitting a file, put them all back together a lot faster then doing

cat file1 file2 file3 file4 file5 > mainfile

or

for i in {0..5}; do cat file$i > mainfile; done

When splitting, be sure to do split -d

for getting numbers instead of letters

Count your source and header file's line numbers. This ignores blank lines, C++ style comments, single line C style comments.

This will not ignore blank lines with tabs or multiline C style comments.

Where filein is the source file, destination.com is the ssh server im copying the file to, -c arcfour,blowfish-cbc is selecting the fastest encryption engines, -C is for online compressions and decompression when it comes off the line - supposed to speed up tx in some cases, then the /tmp/fileout is how the file is saved...

I talk more about it on my site, where there is more room to talk about this:

Or, if you have restricted access for sftp only, I think you can still do this:
