How to install tofrodos in Yosemite via Homebrew?
The tofrodos package doesn't have a tofrodos command line tool. It provides two command line tools: fromdos and todos. You can see them in the package directory after Homebrew installs the package locally:

IanCsiMac:~ |ruby-2.1.2|
&gt; ls /usr/local/Cellar/tofrodos/1.7.13
COPYING              INSTALL_RECEIPT.json bin                  readme.txt           share

IanCsiMac:~ |ruby-2.1.2|
&gt; ls /usr/local/Cellar/tofrodos/1.7.13/bin
fromdos todos

IanCsiMac:~ |ruby-2.1.2|
&gt; which fromdos
/usr/local/bin/fromdos

IanCsiMac:~ |ruby-2.1.2|
&gt; which todos
/usr/local/bin/todos


You need to look for fromdos and todos in your PATH, not tofrodos -- there is no tofrodos command. Similarly, the man pages are for those commands, not tofrodos.
