为啥搞这个
我的项目比较复杂，又好多个材料，时期，组学的数据，公司回来的结果五花八门，特别是result里面的文件名字更是又臭又长。之前老写类似：
for i in `ls *xxx*; do mv $i `echo $i | gsed 's/aaa/bbb/g'`;done
单行确实很方便。
不过前几天玩了玩R的getopt现在又想练习下shell的getopts,就把这个替换文件名字符写成了个小脚本。当然现在还很傻瓜，以后估计会完善... 练练手吧，可能是把简单问题复杂化了...
脚本
#! /bin/bash
set -e ## 报错打断，防止一直错下去
## 帮助内容
func(){
echo "Usage:"
echo "changName.sh [-c conf] [-s string] [-r replace] [-b backup] "
echo "Description"
echo "[-c]:conf, The file name list in one config file, one file per line"
echo "[-s]:string, The string in your file name you want to remove"
echo "[-r]:replace, The string in your file name you want to add"
echo "[-b]:backup, Do you want backup for you original files?"
exit -1
}
## 是否备份原始文件，如果不写-b默认不备份
backup="no"
## 设置各个参数
while getopts 'h:c:s:r:b' OPT;
do
case $OPT in
c) conf="$OPTARG";;
s) string=`echo "$OPTARG"`;;
b) backup="yes";;
r) replace=`echo "$OPTARG"`;;
h) func;;
?) func;;
esac
done
## 提示你的参数设置
echo "Your setting:"
echo "The strings you want remove:" ${string}
echo "The strings you want to replace the removed strings:" ${replace}
echo "The original file was retained:" ${backup}
while read id
do
file=$(basename $id)
old=`echo $file` ## 这里要提取的是字符，echo你上面文件名赋值的结果就是stirng
new=`echo $old | gsed "s/$string/${replace}/g"` ## 你改后的文件名 linux的话把gsed改成sed，如果sed中有变量的话需要双引号
echo "The old filename" "##"$old"##" "has been replaced as" "##"$new"##"
## 执行
if [[ $backup == "yes" ]]; then
#do not backup
cp ${file} ${new}; else
#backup
mv ${file} ${new}
fi
done<$conf
嗯 本来一行的事写了这来长ಥ_ಥ....不过这里多了个是否备份的选项...毕竟我之前干过一下把文件搞丢了的情况.... bash下一顿操作很可能让你的文件找不到了...所以新手还是加上-b吧。
## 写个快捷方式
echo "alias cname='sh ~/08.MyScript/shell/changeName.sh'" >> ~/.bash_alias
source ~/.bash_alias
## 看下帮助
cname -h
/Users/sirus/08.MyScript/shell/changeName.sh: option requires an argument -- h
Usage:
changName.sh [-c conf] [-s string] [-r replace] [-b backup]
Description
[-c]:conf, The file name list in one config file, one file per line
[-s]:string, The string in your file name you want to remove
[-r]:replace, The string in your file name you want to add
[-b]:backup, Do you want backup for you original files?
## 结构
tree
.
├── adf.xxx.xls
├── ba.xxx.xls
├── qwed.xxx.xls
├── wed.xxx.xls
└── wesd.xxx.xls
实际操作
## 将xxx换成yyy并且保留原始文件
ls *xxx* >config ## 做一个配置文件
cname -c config -s 'xxx' -r 'yyy' -b
Your setting:
The strings you want remove: xxx
The strings you want to replace the removed strings: yyy
The original file was retained: yes
The old filename ##adf.xxx.xls## has been replaced as ##adf.yyy.xls##
The old filename ##ba.xxx.xls## has been replaced as ##ba.yyy.xls##
The old filename ##qwed.xxx.xls## has been replaced as ##qwed.yyy.xls##
The old filename ##wed.xxx.xls## has been replaced as ##wed.yyy.xls##
The old filename ##wesd.xxx.xls## has been replaced as ##wesd.yyy.xls##
看下结果

├── qwed.yyy.xls
├── wed.xxx.xls
├── wed.yyy.xls
├── wesd.xxx.xls
└── wesd.yyy.xls
## 将xxx删掉，而且不保留原始文件
cname -c config -s 'xxx' -r '' -b
tree
Your setting:
The strings you want remove: xxx
The strings you want to replace the removed strings:
The original file was retained: no
The old filename ##adf.xxx.xls## has been replaced as ##adf..xls##
The old filename ##ba.xxx.xls## has been replaced as ##ba..xls##
The old filename ##qwed.xxx.xls## has been replaced as ##qwed..xls##
The old filename ##wed.xxx.xls## has been replaced as ##wed..xls##
The old filename ##wesd.xxx.xls## has been replaced as ##wesd..xls##
当然是支持正则表达式的。就不举例子了。可以自己玩一下
