Bash脚本，git和空格的文件名 [英] Bash scripting, git and filenames with spaces

问题描述

我试图用bash脚本自动化一些与git的交互。要做到这一点，我有一个脚本，将SSH和列出所有的存储库，然后克隆它们。部分脚本显示在这里

  DIRS =`ssh $ uls $ p`; $ DIR $中的
;做
 echossh：// $ u $ p $ DIR
 echogit clone ssh：// $ u $ p $ DIR; 
 git clone ssh：// $ u $ p $ DIR 
完成
  

示例参数为

  -u用户@主机
  

和

  -p / cygdrive / c / Documents \ and\设置/ somePath 
  

这对于名称中带有空格的文件路径来说很好，直到git clone部分关于太多空间的错误。如果我复制并粘贴由

  echogit clone ssh：// $ u $ p $ DIR回显的部分; 
  

然后克隆就好了。我试图用引号括起来，但是它引发了一个错误。

 看起来不是git仓库
  

我做错了什么？

使用时的错误克隆ssh：// $ u $ p $ DIR是

 致命：'/ cygdrive / c / Documents \ and\ Settings / somePath / repo1'似乎不是一个git仓库
致命：远程端挂了出乎意料
  

解决方案

我使用了 Gilles 和 ANTAK的答案找到一个解决方案，以及对和 w.com/questions/4937792/using-variables-inside-a-bash-heredoc\">在bash heredoc中使用变量。

正如Gilles我避免使用 ls ，并且我使用Antak建议使用 IFS = $'\\\
'
避免在换行符中使用空格和分隔参数的多个参数。

我最终解决的代码是

  DIRS =`ssh$ u<< ENDSSH 
 cd$ p
 eval'for file in *;做echo \\ $文件;完成'
 ENDSSH` 
 
 IFS = $'\ n'
用于DIR中的$ DIRS; 
 do 
 echossh：// $ u $ p / $ DIR
 done 
 unset IFS 
  

I am trying to automate some of my interactions with git using bash scripts. To do so I have a script that will ssh and list all the repositories and then clone them. Part of the script is shown here

DIRS=`ssh $u "ls $p"`;
for DIR in $DIRS; do
    echo "ssh://$u$p$DIR"
    echo "git clone ssh://$u$p$DIR";  
    git clone ssh://$u$p$DIR
done

Example arguments are

-u user@host

and

-p /cygdrive/c/Documents\ and\ Settings/somePath

This work fine for filepaths with spaces in their names up until the git clone part where it throws an error about too many spaces. If I copy and pasted the part echoed by

echo "git clone ssh://$u$p$DIR";

then it clones just fine. I have tried to surround this in quotes but it throws an error

does not appear to be a git repository

What am I doing wrong?

Edit 1

The errors when using git clone "ssh://$u$p$DIR" is

fatal: '/cygdrive/c/Documents\ and\ Settings/somePath/repo1' does not appear to be a git repository
fatal: The remote end hung up unexpectedly

解决方案

I've used information from Gilles's and Antak's answer to find a solution as well as some other posts on running ssh on a remote machine and using variables in a bash heredoc.

As suggested by Gilles I avoided using ls and I've used Antak's suggestion of using IFS=$'\n' to avoid multiple arguments from spaces and split arguments on line breaks.

The final code I've settled on is

DIRS=`ssh "$u" << ENDSSH
    cd "$p"
    eval 'for file in *; do echo \\$file; done'
ENDSSH`

IFS=$'\n'
for DIR in $DIRS;
    do
    echo "ssh://$u$p/$DIR"
done
unset IFS
