openssl命令可以简单写：

openssl sha1

openssl sha -sha256

openssl md5

openssl base64

openssl base64 -d

urlencode/urldecode[1]

$ alias urldecode='python -c "import sys, urllib as ul; \

    print ul.unquote_plus(sys.argv[])"'

$ alias urlencode='python -c "import sys, urllib as ul; \

    print ul.quote_plus(sys.argv[])"'

$ urlencode 'lalala啦啦啦'

lalala%E5%%A6%E5%%A6%E5%%A6

$ urldecode 'alala%E5%95%A6%E5%95%A6%E5%95%A6'

alala啦啦啦

可以将alias个语句放到.bashrc或者其他shell的启动rc文件里（如：.zshrc），用source载入。

已安装的shell和当前shell：

$ cat /etc/shells

# List of acceptable shells for chpass().

# Ftpd will not allow users to connect who are not using

# one of these shells.

/bin/bash

/bin/csh

/bin/ksh

/bin/sh

/bin/tcsh

/bin/zsh

$ echo $

-/bin/zsh

$ echo $SHELL

/bin/zsh

$ env|grep SHELL

SHELL=/bin/zsh
