yum for cygwin
本帖最后由 damcool 于 2014-04-03 19:26 编辑前些日子在用apt-cyg/cyg-apt来更新自己的cygwin安装包，太TMD让人心焦了。于是自己写了一个"yum for cygwin"，功能还行吧，我需要的都有了。分享一下。#!/bin/bash

YUM for cygwin is a shell script helping cygwin user to install/update/search
packages of cygwin in the manners of similar to redhat yum functions.
Usage: $PROGNAME
Commands:
check-updates List all possible updates of installed package(s)
for cygwin as of now.
clean Clean all cache files and refresh them with latest
data.
info Display the briefing information of the given package(s)
info installed Display the briefing information of installed package(s)
info updates Display the briefing information of updating package(s)
install Install the given package(s) with required package(s)
list List the detail information of the given package(s)
list installed List the detail information of the installed package(s)
list updates List the detail information of the updating package(s)
remove Remove the installed package(s) given by user as well
as the orphan package(s) relatives.
search key-word Search the package database for any package(s) relevant
the given keyword.
update Update all packages or the package(s) given by user.
full-cache Retrive all information from cygwin in cache, it takes
long time to complete while internet connection is slow.
Options:
-y, --yes Always say yes to queries
-h, --help Show current help message of the script usages
Please Report Script Bugs to $AUTHOR_MAIL
