+One can sometimes see people using <code>$| = 1;</code> to perform
+<a xlink:href="http://stackoverflow.com/questions/4538767/how-flush-file-in-perl">autoflushing
+to their filehandles</a>. However, this way is cryptic and is more errorprone
+then doing something like:
+</p>
+<code_blk syntax="perl">
+use IO::Handle;
+
+STDOUT->autoflush(1);
+</code_blk>
+<p>
+This makes the intent clearer and is clearer.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
