Just put this line in a file that resides in your /etc/cron.d/ folder, and you're set.

The -q option is used to suppress php headers.

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.

sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d' /a/file/with/comments

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:

alias stripcomments="sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d'"

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:

while [ 1 ]; do clear; echo 'Star Wars' | figlet -f starwars -t | while IFS="\n" read l; do echo "$l"; sleep 0.01; done; done

NOTICE: You need to install figlet.

On Ubuntu, this command is:

sudo apt-get install figlet

On Debian, this command is:

aptitude install figlet

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.

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.

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.

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'
