Never been to CodeSnippets before?

Snippets is a public source code repository. Easily build up your personal collection of code snippets, categorize them with tags / keywords, and share them with the world (or not, you can keep them private!)

Redirect all output to a single file (See related posts)

Shell commands often output to both standard output and standard error. If you want to send *all* of this to a log file, use the following.

your_shell_script >> /path/to/logfile 2>&1


The 2>&1 bit is the part that redirects standard error to standard out, allowing you to capture both.
