Another neat trick I keep forgetting. If you want to search your shell history, just type in control-r and then your search query. You can browse through the search results by repeatedly pressing control-r. A big time saver if you ask me.

This is quick tip week. Have you ever wanted to preview a file on OSX with quick view without leaving the console. Well here is how:

qlmanage -p file

So if you wanted to preview the file image.png you would type:

qlmanage -p image.png

If you want to see the thumbnail preview of a file instead, just use -t instead of -p.
To close the window either click the cross on the upper right corner or hit control-c to cancel the process. Happy previewing!

Just in case you want to flush the DNS cache on an OSX system for whatever reason, this command gets the job done:

    dscacheutil -flushcache
