Shell 脚本当前目录？

Question

What is current directory of shell script? I this current directory from which I called it? Or this directory where script located?

Answer 1

As already mentioned, the location will be where the script was called from. If you wish to have the script reference it's installed location, it's quite simple. Below is a snippet that will print the PWD and the installed directory:

#!/bin/bash
echo "Script executed from: ${PWD}"

BASEDIR=$(dirname $0)
echo "Script location: ${BASEDIR}"

Answer 2

Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.

DIR="$( cd "$( dirname "$0" )" && pwd )"

By switching directories in a subshell, we can then call pwd and get the correct path of the script regardless of context.

You can then use $DIR as "$DIR/path/to/file"

Answer 3

shell 脚本的当前（初始）目录是您从中调用脚本的目录。

Answer 4

You could do this yourself by checking the output from pwd when running it. This will print the directory you are currently in . Not the script.

If your script does not switch directories, it'll print the directory you ran it from .

Answer 5

要打印当前的工作目录，即 pwd，只需键入如下命令：

echo "the PWD is : ${pwd}"

Answer 6

you could also do it completely using posix shell script

#!/bin/sh

get_current_directory() {
    current_file="${PWD}/${0}"
    echo "${current_file%/*}"
}

CWD=$(get_current_directory)
echo "$CWD"

Answer 7

Adding to mnabil 's comment I think most optimized and logic way is:

realpath `dirname $0`

or with $(), if you don't mind.
