In linux, how do I do something like
echo 'hello world' > log.txt
but instead of overwriting the contents of log.txt, it appends to the end of of log.txt?

In Linux you can also use the useful HERE TAG for multiline append :

hello word 1
hello word 2

While shell may be more powerful than cmd.exe, I would argue it's not more powerful than powershell.– GregDAug 14, 2010 at 23:13

2PowerShell is a Scripting language and for this need to be compared with another scripting language for example Perl then Perl is more more powerful than PowerShell . ;) :D– alerootAug 15, 2010 at 6:50
