什么命令检查Bash shell脚本中是否存在目录?
当前回答
从脚本文件myScript.sh:
if [ -d /home/ec2-user/apache-tomcat-8.5.5/webapps/Gene\ Directory ]; then
echo "Directory exists!"
echo "Great"
fi
Or
if [ -d '/home/ec2-user/apache-tomcat-8.5.5/webapps/Gene Directory' ]; then
echo "Directory exists!"
echo "Great"
fi
其他回答
我发现双括号版本的测试使编写逻辑测试更自然:
if [[ -d "${DIRECTORY}" && ! -L "${DIRECTORY}" ]] ; then
echo "It's a bona-fide directory"
fi
或者对于完全无用的东西:
[ -d . ] || echo "No"
这个答案被包装成一个shell脚本
示例
$ is_dir ~
YES
$ is_dir /tmp
YES
$ is_dir ~/bin
YES
$ mkdir '/tmp/test me'
$ is_dir '/tmp/test me'
YES
$ is_dir /asdf/asdf
NO
# Example of calling it in another script
DIR=~/mydata
if [ $(is_dir $DIR) == "NO" ]
then
echo "Folder doesnt exist: $DIR";
exit;
fi
is目录
function show_help()
{
IT=$(CAT <<EOF
usage: DIR
output: YES or NO, depending on whether or not the directory exists.
)
echo "$IT"
exit
}
if [ "$1" == "help" ]
then
show_help
fi
if [ -z "$1" ]
then
show_help
fi
DIR=$1
if [ -d $DIR ]; then
echo "YES";
exit;
fi
echo "NO";
[ -d ~/Desktop/TEMPORAL/ ] && echo "DIRECTORY EXISTS" || echo "DIRECTORY DOES NOT EXIST"
要检查多个目录,请使用以下代码:
if [ -d "$DIRECTORY1" ] && [ -d "$DIRECTORY2" ] then
# Things to do
fi
