<span style="font-size:18px;">[xqzhang@PEKdev032 ~/NHT201507/test_git/vimconfig]$ git pull -recurse-submoduleserror: did you mean `--recurse-submodules` (with two dashes ?)[xqzhang@PEKdev032 ~/NHT201507/test_git/vimconfig]$ git pull --recurse-submodules</span>

【注】正常命令

git remote add origin https://github.com/zhchnchn/VimConfig.gitgit push -u origin master

4.vimrc配置文件路径 使用脚本自动替换

[xqzhang@PEKdev032 ~/NHT201507/test_git/vimconfig]$ sed -i "s/PATH_VIM/${PATH_VIMCONFIG}/g" vimrc
sed: -e expression #1, char 13: unknown option to `s'

改为：

[xqzhang@PEKdev032 ~/NHT201507/test_git/vimconfig]$ sed -i "s%PATH_VIM%${PATH_VIMCONFIG}%g" vimrc

【注】问题解决参考资料

<span style="font-size:18px;">百思不得其解之下，我做了一些尝试，终于发现，如果使用“%”而不是“/”来作为sed的替换操作的分隔符，就不会出错。代码如下：#!/bin/shPWD=`pwd`DEF_FILE="t1.def"cat $DEF_FILE | sed "s%WKDIR=.*%WKDIR=$PWD%g" #> $DEF_FILEexit 0最后终于发现，问题就出在这个“/”，因为路径里面包含有“/”作为分隔符，这会和sed的替换操作的分隔符“/”引起混淆；所以，只要不使用“/”做分隔符就可以解决这个问题。</span>
