Question

我有一个名为＆＃34; test.sh＆＃34;这将在名为＆＃34; D1＆＃34;的目录中创建24个备份文件。扩展名为.txt~，.bak和以＃开头的12个文件。在这个测试工具中，我必须调用另一个名为＆＃34; clean.sh＆＃34;这将删除给定目录中的所有文件（在本例中为D1）。

这是我的test.sh：

#!/bin/bash
#Create new directory called D1
mkdir D1

#cd into D1
cd ./D1

#Create 12 backup files .bak in D1 (using for loop)
for i in `seq 1 12`;
do
        #echo $I
        touch file$i.bak D1
done

#Create 12 backup files .txt~ in D1 (using set)
touch {a..l}.txt~ D1

#Create 12 files prefix # in D1 (using while loop)
COUNTER=0
while [ $COUNTER -lt 12 ]; do
        touch \#$COUNTER.txt D1
        let COUNTER=COUNTER+1
done

#Once finished creating backup files in all 3 categories, do an ls -l
ls -l

#Invoke clean method here
./cleanUp.sh

#Do final ls - l
ls - l

这是clean.sh：

#!/bin/bash

#Need to pass a directory in as argument
for i in "$@"
do
        echo file is: $I
done

我不确定如何将目录作为参数传入，并且在另一种方法中调用方法会让人感到困惑。谢谢！

你的脚本是个不错的开始 touch命令可以不带参数D1，你的cleanup.sh调用需要一个参数。参数$ {PWD}由shell给出，在这种情况下很容易。（你也可以给出像/ home / mina / test2 / D1这样的参数。）

脚本看起来像

!/bin/bash
#Create new directory called D1
mkdir D1

#cd into D1
cd ./D1

#Create 12 backup files .bak in D1 (using for loop)
for i in `seq 1 12`;
do
        #echo $I
        touch file$i.bak
done

#Create 12 backup files .txt~ in D1 (using set)
touch {a..l}.txt~

#Create 12 files prefix # in D1 (using while loop)
COUNTER=0
while [ $COUNTER -lt 12 ]; do
        touch \#$COUNTER.txt
        let COUNTER=COUNTER+1
done

#Once finished creating backup files in all 3 categories, do an ls -l
ls -l

#Invoke clean method here
./cleanUp.sh ${PWD}

#Do final ls - l
ls - l

现在是清理脚本首先将$I更改为$i，变量名称区分大小写使用for i in "$@"循环访问参数（仅限dir的名称），并且您想要浏览不同的文件名请尝试以下替代方案：

# Let Unix expand the * variable
for i in $1/*; do

# Use a subshell
for i in $(ls "$@"); do

# use a while-loop
ls $@ | while read i; do

# use find and while
find "$1" -type f | while read i; do

# use find and -exec
find "$1" -type f -exec echo File is {} \;

# use find and xargs
find "$1" -type f | xargs echo File is

Bash脚本删除给定目录中的备份文件＆amp;在另一个方法中调用该脚本？
