wget and run/remove bash script in one line
提问by amanada.williams
wget http://sitehere.com/install.sh -v -O install.sh; rm -rf install.sh
That runs the script after download right and then removes it?
下载后运行脚本然后删除它？

I like to pipe it into sh. No need to create and remove file locally.
我喜欢用管道将它导入 sh。无需在本地创建和删除文件。
wget http://sitehere.com/install.sh -O - | sh
wget http://sitehere.com/install.sh -O - | sh

I think you might need to actually execute it:
我认为您可能需要实际执行它：
wget http://sitehere.com/install.sh -v -O install.sh; ./install.sh; rm -rf install.sh
Also, if you want a little more robustness, you can use &&to separate commands, which will only attempt to execute the next command if the previous one succeeds:
另外，如果你想要更健壮一点，你可以使用&&分隔命令，如果前一个命令成功，它只会尝试执行下一个命令：
wget http://sitehere.com/install.sh -v -O install.sh && ./install.sh; rm -rf install.sh

I think this is the best way to do it:
我认为这是最好的方法：
wget -Nnv http://sitehere.com/install.sh && bash install.sh; rm -f install.sh
Breakdown:
分解：
-Nor--timestampingwill only download the file if it is newer on the server-nvor--no-verboseminimizes output, or-q/--quietfor no "wget" output at all&&will only execute the second command if the first succeeds- use
bash(orsh) to execute the script assuming it is a script (or shell script); no need tochmod +x rm -f(or--force) the file regardless of what happens (even if it's not there)- It's not necessary to use the
-Ooption withwgetin this scenario. It is redundant unless you would like to use a different temporary file name thaninstall.sh
-N或者--timestamping只下载服务器上较新的文件-nv或--no-verbose最小化输出，或-q/--quiet根本没有 "wget" 输出&&如果第一个命令成功，只会执行第二个命令- 使用
bash(或sh) 执行脚本，假设它是一个脚本（或 shell 脚本）；没有必要chmod +x rm -f（或--force）无论发生什么的文件（即使它不存在）- 在这种情况下，没有必要使用
-Owith 选项wget。它是多余的，除非您想使用不同的临时文件名install.sh

You are downloading in the first statement and removing in the last statement. You need to add a line to excute the file by adding :
您正在第一个语句中下载并在最后一个语句中删除。您需要添加一行以通过添加以下内容来执行文件：
./install.sh
