Applies (or removes) an advisory lock on a specified file
Although it doesn't have feature-parity, the script is compatible with flock(1).
The script was created because, although the OS has the relevant API (i.e. flock(2)), Mac OS doesn't have the flock cli utility.
This script provides a (mostly) drop-in cross-platform option.
The script only supports acquiring exclusive locks (in blocking or non-blocking mode)
The find command accepts and -exec argument, allowing you to pass matching files into an arbitrary command.
It's pretty useful, but sometimes you want to be able to have it invoke a custom function, which it can't do without a little bit of tweaking
This snippet details how to have find invoke a custom shell function against each matching result, the example uses BASH but the same should be possible with ZSH, DASH, ASH, KSH etc
Flux's stdlib provides the function StateDuration() which adds a column with an incrementing counter for as long as the data matches the provided predicate (i.e. indicates a specific state).
However, this counter resets when the state changes, so the duration column only tells you how long each instance of the state lasted and because the counter is added to each row, you cannot simply sum() it to calculate the total time spent in that state (say a switch being on)
However, it's possible to calculate the total amount of time spent in a state using the elapsed()function with a map().
This snippet details how to define a set of predicate based states for a stream of data and then calculate the total time spent in each of those states
Nowadays, most sites will find that the majority of their traffic arrives as the result of someone else sharing or "likeing" the content on Social Media. As a result, it's desirable to make the act of sharing as easy as possible.
The various social networks often provide "share this" widgets that can be embedded into sites. However, these involve the user's browser requesting resources from the social network, and these requests are known to be data-mined in order to track users across the web and profile their browsing habits (to better sell ads).
However, most social media networks do make it possible to create a share button which works via a simply hyperlink.
