urlencode/urldecode[1]

$ alias urldecode='python -c "import sys, urllib as ul; \    print ul.unquote_plus(sys.argv[1])"'$ alias urlencode='python -c "import sys, urllib as ul; \    print ul.quote_plus(sys.argv[1])"'$ urlencode 'lalala啦啦啦'lalala%E5%95%A6%E5%95%A6%E5%95%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(1).# 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 $0-/bin/zsh$ echo $SHELL/bin/zsh$ env|grep SHELLSHELL=/bin/zsh
