我的任务是编写一个 Unix shell 脚本,它询问用户目录的名称,然后像find
.
这是我到目前为止所拥有的:
#!/bin/bash
dir_lister()
{
cd "$1"
echo "$1"
list=$(ls -l ${1})
nolines=$(echo "$list" | awk 'END{printf "%d",NF}')
if [ $nolines -eq 2 ]
then
echo "$1"
return
fi
filelist=$(echo "$list" | grep ^-.*)
dirlist=$(echo "$list" | grep ^d.*)
filename=$(echo "$filelist"| awk '{printf "%s\n",$NF}')
present=$(pwd)
echo "$filename"| awk -v pres=$present '{printf "%s/%s\n",pres,$0}'
dirlist2=$(echo "$dirlist" | awk '{printf "%s\n",$NF}')
echo "$dirlist2" | while IFS= read -r line;
do
nextCall=$(echo "$present/$line");
dir_lister $nextCall;
cd ".."
done
cd ".."
}
read -p "Enter the name of the direcotry: " dName
dir_lister $dName
问题是,在三个目录的深度之后,这个脚本进入了一个无限循环,我不明白为什么。
编辑:
这是我在查看您的答案后提出的代码,它的目录深度仍然不超过 1:
#!/bin/bash
shopt -s dotglob # don't miss "hidden files"
shopt -s nullglob # don't fail on empty directories
list_directory()
{
cd "$2"
cd "$1"
##echo -e "I am called \t $1 \t $2"
for fileName in "$1/"*
do
##echo -e "hello \t $fileName"
if [ -d "$fileName" ];
then
echo "$fileName"
list_directory $fileName $2
else
echo "$fileName"
fi
done
}
read -p "Enter the direcotory Name: " dirName
var=$(pwd)
list_directory $dirName $var
