Cygwin自用脚本programs,列出自己定义的函数(主要用于快速运行Windows程序)和alias别名,并实现简单查找

作者:互联网

#!/bin/bash
#查询在/v/bin/aliaswinapp中已经定义的Win程序快捷方式
. /v/bin/aliaswinapp
programs=$(declare -F|awk "{print \$NF}"|grep -vE "^_")

#echo "programs: $programs"

##仿ls,横向列出
if [ $# -lt 1 ] || ([ $# -eq 1 ] && ([[ "$1" == "ls" ]] || [[ "$1" == "-s" ]]));then
	#echo -e "$programs"|tr '\n' '\t'
	str=$(echo -e "$programs"|tr '\n' '\t'|sed -r 's/[ \t]*$//g')
	#借助python格式化输出列表
	/usr/bin/env python3 /v/bin/python-formater.py "${str}"
	exit 0
##仿ls -l,纵向列出
elif [ $# -eq 1 ] && ([[ "$1" == "ll" ]] || [[ "$1" == "-l" ]]);then
	echo "$programs"
	exit 0
##列出全部,包括所有alias定义定义的值
elif [ $# -eq 1 ] && ([[ "$1" == "all" ]] || [[ "$1" == "-a" ]]);then
	. ~/.bash_profile >/dev/null
	allAlias=$(alias -p|grep -iE '^alias '|awk -F '[ =]' '{print $2}')
	programs=$(echo -e "$programs\n$allAlias"|sort -d)
	echo "$programs"
	exit 0
##列出全部,包括所有alias定义定义的值,并且以关键字查找,$2为要查找的关键字
##本功能和-A分支的区别在于本分支还提供 whereis 查找,另本分支查找参数可省略(省略时列出全部),不支持grep原生选项
## -A 分支查找参数是必须的,且提供grep原生接口,可以实现正则表达式查找等其他功能;
elif [ $# -eq 2 ] && ([[ "$1" == "all" ]] || [[ "$1" == "find" ]] || [[ "$1" == "-a" ]]) && [ ! -z "$2" ];then
	. ~/.bash_profile >/dev/null
	allAlias=$(alias -p|grep -iE '^alias '|awk -F '[ =]' '{print $2}')
	programs=$(echo -e "$programs\n$allAlias"|sort -d)
	programFind=$(echo "$programs"|grep -i "$2")
	#如果aliaswinapp和alias均未找到结果,则通过whereis再次查找
	if [ -z "$programFind" ];then
		whereis $2
	else
		echo "$programFind"
	fi
	exit 0
##查找aliaswinapp中具名function的定义
elif [ $# -eq 2 ] && ([[ "$1" == "-d" ]] || [[ "$1" == "define" ]] || [[ "$1" == "-f" ]]) && [ ! -z "$2" ];then
	fn_defined=$(declare -f $2)
	#如果 aliaswinapp 找不到已有定义,则更深一步去查询 alias 记录
	[ -z "${fn_defined}" ] && {
		. ~/.bash_profile >/dev/null
		. ~/.bashrc >/dev/null
		alias $2 2>/dev/null
		exit 0
	}
	echo "${fn_defined}"
	exit 0
##关键词查找,不区分大小写
elif [ $# -eq 1 ] && [[ ! "$1" =~ ^\-[a-zA-Z]$ ]];then
	programFind=$(echo "$programs"|grep -i "$1")
	#如果aliaswinapp未找到结果,则通过whereis再次查找
	if [ -z "$programFind" ];then
		echo -e "not found in /v/bin/aliaswinapp;"
		whereis $1
	else
		#echo "$programFind"
		#借助python格式化输出列表
		/usr/bin/env python3 /v/bin/python-formater.py "`echo "$programFind"|tr '\n' '\t'`"
	fi
	exit 0
elif [[ "$1" == "-L" ]] || [[ "$1" == "-F" ]];then
	#列出所有的函数和alias详细内容,并尽可能按合理顺序排序,grep时同时也在alias内容中查找
	#妙用1:programs -L alias.*wget
	#妙用2:programs -L alias.*ssh
	shift
	. ~/.bash_profile >/dev/null
	. ~/.bashrc >/dev/null
	allAlias=$(alias -p|grep -iE '^alias ')
	programs=$(echo -e "$programs"|sed 's/^/function=/g')
	programs=$(echo -e "$programs\n$allAlias"|sort -t '=' -k 2 -d|sed -r '/^[!a-zA-Z]/!d'|sed 's/^function=//')
	if [ $# -eq 0 ];then
		echo "$programs"
	elif [ $# -eq 1 ];then
		echo "$programs"|grep -i $1
	else
		echo "$programs"|grep $@
	fi
	exit 0
##以下情况向grep直接传递参数,直接接收grep原生各项参数
elif [[ "$1" == "-A" ]];then
	##查询所有,包含aliaswinapp内函数定义和用户alias别名,查找参数必不可少,grep时仅仅在alias名称中查找
	##注意区分和-a(小写a)分支的区别
	shift
	. ~/.bash_profile >/dev/null
	. ~/.bashrc >/dev/null
	allAlias=$(alias -p|grep -iE '^alias '|awk -F '[ =]' '{print $2}')
	programs=$(echo -e "$programs\n$allAlias"|sort -d)
	echo "$programs"|grep $@
	exit 0
else
	#仅列出/v/bin/aliaswinapp中函数定义,并供grep原生参数查找
	echo "$programs"|grep $@
fi
