用点创建的目录名，使用 shell 脚本

Question

I am using Cygwin Terminal to run shell to execute shell scripts of my Windows 7 system. I am creating directory , but it is getting created with a dot in name.

test.sh

#!/bin/bash
echo "Hello World"
temp=$(date '+%d%m%Y')
dirName="Test_$temp"
dirPath=/cygdrive/c/MyFolder/"$dirName"
echo "$dirName"
echo "$dirPath"
mkdir -m 777 $dirPath

on executing sh test.sh its creating folder as Test_26062015 while expectation is Test_26062015 .Why are these 3 special charterers coming , how can I correct it

Answer 1

Double quote the $dirPath in the last command and add -p to ignore mkdir failures when the directory already exists: mkdir -m 777 -p "$dirPath" . Besides this, take care when combining variables and strings: dirName="Test_${temp}" looks better than dirName="Test_$temp" .

Also, use this for static analysis of your scripts.

UPDATE: By analyzing the debug output of sh -x , the issue appeared due to DOS-style line-endings in the OP's script. Converting the file to UNIX format solved the problem.
