如何在linux中检查目录是否存在。？

Question

给定文件路径（例如/src/com/mot ），如何检查mot是否存在，如果不使用Linux或shell脚本，则创建它？

Answer 1

With bash/sh/ksh, you can do:

if [ ! -d /directory/to/check ]; then
    mkdir -p /directory/toc/check
fi

For files, replace -d with -f , then you can do whatever operations you need on the non-existant file.

Answer 2

mkdir -p创建目录而不会出现错误（如果已存在）。

Answer 3

test -d /src/com/mot || mkdir /src/com/mot

Answer 4

Well, if you only check for the directory to create it if it does not exist, you might as well just use:

mkdir -p /src/com/mot

mkdir -p will create the directory if it does not exist, otherwise does nothing.

Answer 5

Check for directory exists

if [ -d "$DIRPATH" ]; then
    # Add code logic here 
fi

Check for directory does not exist

if [ ! -d "$DIRPATH" ]; then
    # Add code logic here
fi

Answer 6

This is baisc, but I think it works. You'll have to set a few variables if you're looking to have a dynamic list to cycle through and check.

if [ -d /src/com/mot ];
then
    echo Directory found
else
    mkdir /src/com/mot
fi

Hope that's what you were looking for...
