This is useful for sending data between 2 computers that you have shell access to. Uses tar compression during transfer. Files are compressed & uncompressed automatically. Note the trailing dash on the listening side that makes netcat listen to stdin for data.

on the listening side:

explanation: open netcat to -l listen on -p port 2022, take the data stream and pipe to tar -x extract, -v verbose, -f using file filename - means "stdin"

on the sending side:

explanation: compress all files in current dir using tar -c create, -v verbose, -f using file, - filename - here means "stdout" because we're tar -c instead of tar -x, -w3 wait 3 seconds on stream termination and then end the connection to the listening host name_of_listening_host, on port 2022

Turns regular quotes into curly quotes, also converts hyphens to dashes using a heuristic and outputs the result as UTF-8, suitable to copy/paste into wordprocessor.

requires: http://daringfireball.net/projects/smartypants/ (which does most of the work)

(I renamed smartypants.pl to smartypants before adding it to my $PATH)

Also requrires PHP with the multibyte module installed (its installed by default with PHP, but the sysadmin on one server I use disabled it... presumadly to increase performance or something).

over works like 'more' or 'less', but it pretty print the source code

Benefit is that it doesn't make you keep the terminal open.

Look search for lines in a file that beginning with a given string.

Same as $ grep ^n /etc/passwd

Add an entry to Microsoft Forefront's "Excluded file and locations". Replace C:\temp\evil.exe with desired folder to exclude. Requires administrative privileges.

Examples:

%SystemRoot%\system32\evil.exe

C:\*.exe

C:\

C:\temp\*.*

\\remotesvr\share

\\remotesvr\share\evil.exe

\\remotesvr\share\folder\evil.exe

Some servers don't have ssh-copy-id, this works in those cases.

It will ask for the destination server, this can be IP, hostname, or user@hostname if different from current user.

Ssh keygen will let you know if a pubkey already exists on your system and you can opt to not overwrite it.

This was tested on Ubuntu 12.04 (Precise) LTS Server. It returns the name of the symlink within /dev/disk/by-id for the physical drive you specify. Change /dev/sda to the one you want, and replace ata- with scsi- or the appropriate type for your drive.

I used this to pre-configure grub-pc during a non-interactive install because I had to tell it which disk to install grub on, and physical disks don't have a UUID such as that blkid provides.

Random Cyanide and Happiness comics from explosm.net. I use this command http://www.commandlinefu.com/commands/view/3477/random-xkcd-comic and update it for explosm.net

--edit : modification for *.jpeg files + guest authors

This command produces the output of "du -sk testfile" in every 10 seconds. You can change the command to be whatever you want.

The magic is performed by the parameter -t

I had a file named " " (one space) and needed a way to see what the real filename was so I could remove it. sed to the rescue.

Run program as root by SSH key forwarding instead of sudoers.

Put this alias line in .bashrc or wherever you like. Alias arguments might need extra escaping.

You might wonder about security. But you'd block out root login as much as possible of course. In sshd_config you put this:

PermitRootLogin no

Match Address 127.0.0.1

  PermitRootLogin without-password

alternatives:

xinit $(which gnome-awesome-session)

with cat /usr/local/bin/gnome-awesome-session:

#!/bin/bash

exec gnome-session --session awesome "$@"
