Another example: imagine you've found a great command on the internet with a large number of parameters, such as a mencode command for converting a video file. Due to the web page presentation, when you copy and paste the command, it ends up over 20 lines. Instead of going through and removing all newline characters, simply start Nano with nano -r1000. Paste the text in (Shift+Insert works in many X terminals), hit Ctrl+J and it'll be folded into one neat line that you can paste into a terminal. Alt+J justifies all paragraphs in the file at once.
Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.
