我正在尝试编写一个请求目录的bash脚本,然后在确认后删除该目录。我还需要它告诉用户目录是否为空,并询问他们是否要删除它。
我想我会使用rmdir并检查返回值以确保删除目录,如果不是为什么,但到目前为止我不知道返回值等于EEXIST或ENOTEMPTY。到目前为止,我唯一的错误值是1。
如果目录中有文件,返回值应该是多少?

单独检查。不完美,但一个开始
if [ ! -e "$DIR" ]
then
echo "ERROR: $DIR does not exist" >&2
elif [ ! -d "$DIR" ]
then
echo "ERROR: $DIR is not a directory" >&2
elif [ ! -r "$DIR" ]
then
echo "ERROR: $DIR cannot be read" >&2
elif [ $(ls -a $DIR | wc -l) -gt 2 ]
then
echo "ERROR: $DIR is not empty" >&2
else
rmdir $DIR
fi
注意:rmdir
仍可能失败。我想到的是您对$DIR
的父目录没有写权限。

您可以尝试使用此代码:
#!/bin/bash
check_path() {
if [ "x$1" = "x" ]
then
echo "ERROR: You have to specify a valid path."
exit 1
fi
if ! [ -d "$1" ]
then
echo "ERROR: The specified path does not exists or it's not a directory"
exit 1
fi
X="`find \"$1\" -maxdepth 1 | tail -n 2 | wc -l`"
if [ $X -gt 1 ]
then
X="R"
else
X=""
fi
while [[ "x$X" != "x" && ("x$X" != "xs" && "x$X" != "xn") ]]
do
echo "The specified path ($1) is not empty. Are you sure you want to delete it anyway? (S/n)"
stty -echo
read X
stty echo
done
if [ "x$X" == "xn" ]
then
echo "Operation interrupted by the user."
exit 0
fi
}
echo -n "Please insert the path to delete: "
stty -echo
read DIRNAME
stty echo
echo
check_path "$DIRNAME"
echo "Removing path $1"
echo rm -fr "$DIRNAME"
