swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
4 random words are better than one obfuscated word

$ wget -qO - "http://www.google.com/dictionary/json?callback=dict_api.callbacks.id100&q=steering+wheel&sl=en&tl=en&restrict=pr,de&client=te"
this does the actual google dictionary query, returns a JSON string encapsulated in some fancy tag
$ sed 's/dict_api\.callbacks.id100.//'
here we remove the tag beginning
$ sed 's/,200,null)//'
and here the tag end
There are also some special characters which could cause problems with some JSON parsers, so if you get some errors, this is probably the case (sed is your friend).
I laso like to trim the "webDefinitions" part, because it (sometimes) contains misleading information.
$ sed 's/\,\"webDefinitions.*//'
(but remember to append a "}" at the end, because the JSON string will be invalid)
The output also contains links to mp3 files with pronounciation.
As of now, this is only usable in the English language. If you choose other than English, you will only get webDefinitions (which are crap).
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token.
This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use:
`awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'`
You must adapt the command line to include:
* $MFA_IDis ARN of the virtual MFA or serial number of the physical one
* TTL for the credentials
Uses inotifywait from inotify-tools ( http://wiki.github.com/rvoicilas/inotify-tools/ ), that is compatible only with linux.
Usefull when you work with files that have to be compiled.. latex, haml, c..
This lets you replace a file or directory and quickly revert if something goes wrong. For example, the current version of a website's files are in public_html. Put a new version of the site in public_html~ and execute the command. The names are swapped. If anything goes wrong, execute it again (up arrow or !!).
Many times I give the same commands in loop to find informations about a file. I use this as an alias to summarize that informations in a single command. Now with variables! :D
The 30 means start extracting frames from 30 seconds into the video. The 3 means extract the next 3 seconds from that point. The fps can be adjusted based on your preferences. The 320 is the width of the gif, the height will be calculated automatically.
input.mp4 is the video file, which can be any video file ffmpeg supports. The output.gif is the gif created.
