    alias lsd="ls -ltrF | grep ^d"

Helps me quickly list only directories. Any better alternatives ?

Using `find` is nice to get just directories:

$ find . -type d -maxdepth 1

edit: for the same output as your command you can use:

  dir -l

Dunno what "better" means, but this also works:

find -maxdepth 1 -type d

faucet 80 --in cat This is useful for creating a connection for receiving the input of what you get... e.g. running faucet 80 --in cat and later curl http://127.0.0.1:80 will deliver to you console : GET / HTTP/1.1 User-Agent: curl/7.21.4 (i686-pc-linux-gnu) libcurl/7.21.4 OpenSSL/0.9.8n zlib/1.2.5 libidn/1.19 Host: 127.0.0.1:900 Accept: /

Alternatively you could do

  netcat -l -p 80

I have this in my .bashrc:

function lc() { if [[ "$#" -gt 1 ]]; then for DIR in "$@"; do echo -n "$DIR - " ; ls -AU1 $DIR | wc -l ; done ; else ls -AU1 "$@" | wc -l ; fi; }

So, "lc /dir" will count the number of files in /dir and "lc /dir/*" will count the files in subdirectories of /dir. This is useful if you're working in an environment where you may have thousands of files in a directory, and a regular "ls -l" will lock your terminal while it eats your entire scrollback buffer.
