There isn't official documentation for the command line arguments as of redis-cli.  If you type --help for the command line arguments you get the following smorin$ ./redis-2.2.4//src/redis-cli --help redis-cli 2.2.4 Usage: redis-cli [OPTIONS] [cmd [arg [arg ...]]]   -h    Server hostname (default: 127.0.0.1)   -p        Server port (default: 6379)   -s      Server socket (overrides hostname and port)   -a    Password to use when connecting to the server   -r      Execute specified command N times   -n          Database number   -x               Read last argument from STDIN   -d   Multi-bulk delimiter in for raw formatting (default: \n)   --raw            Use raw formatting for replies (default when STDOUT is not a tty)   --help     ...

There is only one argument for redis-server.  It's the path to the redis.conf file.  There is a example of this file in the redis src base.  There isn't a official documentation page as of 6/2011 $redis-server /path/to/redis/config/redis.conf

Quoted from Stackoverflow - Original Link Below ( love this post, these three are my biggest emacs annoyences) Hi there, I am currently playing around with emacs and happy with most of the concepts. But I really adored the convenience of the three vim commands: dd,o,O Hopefully you can tell me how to mirror them in emacs :) dd  - deletes whole line, including newline, no matter where the cursor is. I found something similar to do the trick: C-a C-k C-k While  C-a  moves the cursor to the beginning of the line, the first  C-k  kills the text, the second one kills the newline. The only problem is that this is not working on empty lines where I only need to type C-k  which is quite inconvenient as I have to use different commands for the same task: killing a line. o / O  - creates a new empty line below / above cursor and moves cursor to the new line, indented correctly Well,  C-a C-o  is nearly like  O , just the idention is missing....

Multiline strings can be assigned in bash using one of these two examples. $ String='foo1 foo2 foobar2' STRING=$( cat <<EOF foo1 foo2 foobar2 EOF )

Editing binary files   Edit Use the  -b  option to set binary mode before editing a binary file, for example: vim -b myfile.bin If wanted, you can display nonprintable characters in hex, and you can wrap lines: :setlocal display=uhex :setlocal wrap In normal mode, type  g  then Ctrl-G to display the byte number at the cursor, or type a byte number then  go  to jump to that byte (for example,  123go  will jump to byte number 123). The first byte in the file has byte number 1. The following command replaces the buffer with a hex dump: :%!xxd You can edit the hex bytes, then convert the file back to binary with the command: :%!xxd -r The above command reverses the hex dump by converting the hex bytes to binary (the printable text in the right column is ignored). http://vim.wikia.com/wiki/Hex_dump
