Deletes thousands of files at one go, I'm not able to recall the exact # of files that rm can delete at one go(apprx. around 7000.)

plays with bash arrays. instead of storing the list of files in a temp file, this stores the list in ram, retrieves the last element in the array (the last html file), then removes it.

Strips comments from at least bash and php scripts. Normal # and // as well as php block comments

removes all of the:

empty/blank lines

lines beginning with #

lines beginning with //

lines beginning with /*

lines beginning with a space and then *

lines beginning with */

It also deletes the lines if there's whitespace before any of the above.

Add an alias to use in .bashrc like this:

Change YOUR TEXT HERE to the text you want.

On figlet -f banner, you can change it to any figlet font you have installed.

One variant for Star Wars fans could be this:

NOTICE: You need to install figlet.

On Ubuntu, this command is:

On Debian, this command is:

Displays SuSE release information

Like the http://www.commandlinefu.com/commands/view/6327/open-file-with-sudo-when-there-is-no-write-permission, but works (in zsh; my commandlinefu is not strong enough to understand why bash don't like it) with vim options, like -O, and many input files.

There could be other mistakes.

Usage: jd dir

Requires globstar. To set globstar use:

Valid JSON is a subset of YAML; no transformation is necessary; however, YAML has many syntax features that are not valid JSON, so you can't do the reverse as easily.

Create a shortcut on your desktop and insert the above command.

I don't know if you've used sqsh before. But it has a handy feature that allows you to switch into vim to complete editing of whatever complicated SQL statement you are trying to run.

But I got to thinking -- why doesn't bash have that? Well, it does. It's called '|'!

Jk.

Seriously, I'm pretty sure this flow of commands will revolutionize how I administer files. And b/c everything is a file on *nx based distros, well, it's handy.

First, if your ls is aliased to ls --color=auto, then create another alias in your .bashrc:

alias lsp='ls --color=none'

Now, let's say you want to rename all files that begin with the prefix 'ras' to files that begin with a 'raster' prefix.

You could do it with some bash substitution. But who remembers that? I remember vim macros because I can remember to press 'qa' and how to move around in vim. Plus, it's more incremental. You can check things along the way. That is the secret to development and probably the universe. So type something like:

lsp | grep ras

Are those all the files you need to move? If not, modify and re-grep. If so, pipe it to vim.

lsp | grep ras | vim -

Now run your vim macros to modify the first line. Assuming you use 'w' and 'b' to move around, etc., it should work for all lines. Hold down '@@', etc., until your list of files has been modified from

ras_a.h

ras_a.cpp

ras_b.h

ras_b.cpp

to:

mv ras_a.h raster_a.h

mv ras_a.cpp raster_a.cpp

mv ras_b.h raster_b.h

mv ras_b.h raster_b.cpp

then run :%!bash

then run :q!

then be like, whaaaaa? as you realize your workflow got a little more continuous. maybe. YMMV.

Could use your ssh bash history if your known_hosts are hashed and you want to keep it hashed

-d, --delete

Delete a user?s password (make it empty). This is a quick way to disable a password for an account. It will set the named account passwordless.

it recursively searches your project's directories and sum the lines of every source [.c or .h]. Then it gives you the total.

It is an easy method unzip a file and copy it to remote machine. No unziped file on local hard drive

Every 20 minutes test if host with IP 192.168.0.14 is 'dead' or not reachable.

The line should be put in your crontab file.

Get windows version with servicepack and hostname

Paste what you previously wrote in INSERT MODE, for example:

1. Write 'foo' in INSERT MODE

2. Return to NORMAL MODE

3. Press "." and it will paste 'foo'

Get external IP of the current machine via http://cmyip.com

when you can do it , avoid pipe

A script that checks if your environment is correctly configured for using cobbler.

doesnt require knowing the password to pdf

Also works with files:

Hello world

SGVsbG8gd29ybGQK

To decrypt use the -d option:

Hello world

Kills all processes owned by user MYWIFE (replace MYWIFE with username or ID of your choice)
