创建自动运行脚本用来备份文件

基础

  • 输出到文件
1
echo "$1" > $logFile
  • 输出到文件:尾部插入
1
echo "$1" >> $logFile
  • 输出到文件:某行插入

# 格式 ni代表第n行前插入,na代表第n行后插入
sed -i '' 'ni\
something
' $logFile

# 双引号才可以调用变量,格式如下
sed -i '' "1i\\
\\${1}\\
" $logFile

# 多行建议这样使用
file="filePath"
multiLineCode="\
\\
line 1 \\
line 2 \\
line 3 \\
\\"

sed -i '' "1i\\
${multiLineCode}
" $file
  • 删除文件/文件夹
1
2
rm -f someFile
rm -rf someDir
  • 复制文件/文件夹
1
2
cp -f aFile bFile
cp -rf aDir bDir
  • 遍历数组
1
2
3
4
for dir in $SubFolderArray
do
echo $dir
done
  • 倒序遍历数组
1
2
3
4
5
for (( i=${ArrayLength}-1; i>=0; i-- ));
do
dir=${SubFolderArray[$i]}
echo $dir
done
  • 判断字符串是否以xxx开头
1
2
3
if [[ $dir == .svn_* ]]; then
...
fi
  • 判断字符串是否包含子串
1
2
3
if [[ $dir == *svn_* ]]; then
...
fi
  • 判断数字大于xx等
1
2
3
if (( ${TotalBack} > 10 )); then
...
fi
