Alias to play flash videos with mplayer. You can replace mplayer with your favorite video player.
This alias supports Chrome & Firefox's way of handling the flash plugin. It will play all the videos in the cache. Note that certain videos might never make it to the cache, if the publisher ask for them not to: they will just be loaded in RAM.
A variant if you're just interested in playing the audio, for example for a music :
alias flashmusic="mplayer -vo null \$(find /proc/\$(pgrep -f 'libgcfl|libflashplayer')/fd/ -printf '%p %l\n' |grep FlashXX | cut -d\ -f1)"
requires a gmail account, it opens Google tasks in a self contain window, to write your todo list and have it sync online yay =)
Syntax outside of an alias would be printf %b \\033c. This clears the screen and removes scrollback. Works on gnome-terminal and the XFCE's Terminal, and XTerm. It does clear the screen in Konsole and the Mac Terminal, but does not clear scrollback.
Uses printf command to resize terminal.
So far, this is tested to NOT work in Konsole. Works with Mac Terminal, XFCE Terminal, XTerm, gnome-terminal.
Creates an alias that reports your hostname and IP for you computer. Getting the quotes in an alias with awk commands can be a painful. Need uname and ifconfig--both are included in most unix distributions, I believe. Hope it is useful.
I put this line in my ~/.bashrc file (which I source via ~/.bash_profile). Now, when I need to install a package, I typed *install* instead of the longer version.
use python as calculator, press ctrl+d to exit
reminder: when doing factions add atleast one decimal number like so
22.0/7 or 22/7.0
Prints out the list of date(1) format codes, for quick easy reference.
Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) )
This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.
cn stands for "Cat Null"
The idea is that sometimes you run across something on maybe a webpage - like commandlinefu - that you want to try out on your terminal. You could put a '#' in and then paste it, but what if it is several lines?
This command will echo the pasted characters to the screen and divert them to the bit bucket.
Put this simple alias in your .bashrc, hit cn, paste away, and hit a ctrl+c or a ctrl+d when you are done to get your prompt back.
another formatting/oneliner for lsof User - Process - Port
This alias is meant to append n (here is n=10) most recently used cd commands to the bottom of history file. This way you can easily change to one of previous visited directories simply by hitting 1-10 times arrow up key.
Hint: You can make more aliases implying the same rule for any set of frequently used long and complex commands like: mkisof, rdesktop, gpg...
Put the function in your .bashrc and use "map [alias]" to create the alias you want. Just be careful to not override an existing alias.
google query_with_spaces "
so, make sure to end your query with a double quote
Create an alias to list all contents of the current directory in "reverse" time order. Thus the last modified file will appear just above your next prompt. Useful for remembering where you left off modifying files in a folder or just noting recent changes.
csh format but bash syntax similar
it's a mixed environment where I work, and since we still use WINS services, this is often a quick and dirty way for me to obtain a mac-address for a hostname. please note that nmblookup is part of the samba suite. Just another one of those nearly useless commands that is super cool when and only when you need it.
1. Get name of task by task=$(basename "$(pwd)")
2. Check whether "$task.c" exists as a file
3. open "$task.c", "$task.in", "task.out" in vim with such layout.
| | $task.in |
| | |
| | $task.out |

Personally I think line wrap in default df command is annoying for scripting & seeing. So I overwrite it. Maybe more work should be done if wrapped line is over 2...
