Render man page in *temporary* PDF (works in Gnome)

Yeah yeah, another "render man page in pdf", but this time it creates a temporary PDF that stays resident in memory for viewing, but is eliminated on the filesystem. Replace evince with your PDF viewer of choice.

Generate random sensible passwords, and copy them to the clipboard

Use the excellent sensiblepasswords.com to a generate random (yet easy-to-remember) password every second, and copy it to the clipboard. Useful for generating a list of passwords and pasting them into a spreadsheet. This script uses "madebynathan"'s "cb" function (http://madebynathan.com/2011/10/04/a-nicer-way-to-use-xclip/); you could also replace "cb" with xclip -selection c Remove "while true; do" and "; done" to generate and copy only 1 password.

Makes mplayer show file played through libnotify, 140 characters

Will finish automagically when mplayer quits. Can be run from any directory. It seems to finish by it self rarely, probably because of some timing issue? There's probably a way around that which I can't think of right now Show Sample Output

Poor man's watch: Repeat a command every N seconds

Usage: watch ls -l Basic but usable replacement for the "watch" command for those systems which don't have it (e.g. the Solaris I'm trapped on). Type Ctrl+V to escape the following Ctrl+L which clears the screen. It will be displayed as "^L".

Matrix Style

A tweak using Patola's code as a base, this full-width green matrix display has all the frills (and all the printable characters). You don't need the surrounding parens if you don't care about losing globbing capabilities. Z-shell (/bin/zsh) needs neither the parens nor the `set -o noglob` Screen shot (animated): http://desmond.imageshack.us/Himg32/scaled.php?server=32&filename=matrixh.gif&res=landing If it's too slow, try lowering the `sleep 0.05` or even replacing it with `true` (which is faster than `sleep 0`). I squashed it as narrow as I could to conserve space, though somebody could probably squeeze a char or two out. Enjoy!

Notify by text-message when command completes

Replace "4158575309@txt.att.net" with your carrier's SMS gateway identifier. The one in the sample is for AT&T. More here https://en.wikipedia.org/wiki/List_of_SMS_gateways. Helpful for getting notifications about long running commands. ";" executes regardless of exit status of last command. && will only notify you if the command succeeds.

repeat a command every x seconds

For use when you can't use "watch" (user-defined functions, aliases). This isn't mine - its an alternate posted in the comments by flatcap, and is the shortest and easiest to remember.

Display CPU usage in percentage

Using the output of 'ps' to determine CPU usage is misleading, as the CPU column in 'ps' shows CPU usage per process over the entire lifetime of the process. In order to get *current* CPU usage (without scraping a top screen) you need to pull some numbers from /proc/stat. Here, we take two readings, once second apart, determine how much IDLE time was spent across all CPUs, divide by the number of CPUs, and then subtract from 100 to get non-idle time. Show Sample Output

```
1.84% CPU Usage

avoid ssh hangs using jobs

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system. Maybe there's an easier way to set a timeout in the ssh options...

delete a line from your shell history

Change every instance of OLD to NEW in file FILE

Very quick way to change a word in a file. I use it all the time to change variable names in my PHP scripts (sed -i 's/$oldvar/$newvar/g' index.php)

using tee to echo to a system file with sudo privileges

We sometimes need to change kernel parameters by echoing the file . This needs root privilege and if we do it using sudo like this , it fails $ sudo echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor -bash: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: Permission denied We can achieve this with the tee command by just doing sudo without logging as root user http://www.zaman4linux.in/2010/09/using-tee-to-echo-to-system-file-with.html

Anti Syn Ddos

Ddos syn attack

Run bash on top of a vi session (saved or not saved), run multiple commands, instead of one at a time with :!(bashcommand), type exit and [enter] to get back to where you left off in vi.

Helps when I'm editing a script and want to double check some commands without having to exit out of vi multiple times or having to use another terminal session.
