下面是易于记住的脚本:

DIR="$( dirname -- "${BASH_SOURCE[0]}"; )";   # Get the directory name
DIR="$( realpath -e -- "$DIR"; )";    # Resolve its full path if need be

我想确保剧本在其目录中运行。

cd $(dirname $(which $0) )

接下来,如果你真的想知道你在哪里运行,然后运行下面的命令。

DIR=$(/usr/bin/pwd)

使用“0”字母:

#!/usr/bin/env bash

echo "The script you are running has basename $( basename -- "$0"; ), dirname $( dirname -- "$0"; )";
echo "The present working directory is $( pwd; )";

使用 pwd 单独不会工作,如果您不从它包含的目录中运行脚本。

[matt@server1 ~]$ pwd
/home/matt
[matt@server1 ~]$ ./test2.sh
The script you are running has basename test2.sh, dirname .
The present working directory is /home/matt
[matt@server1 ~]$ cd /tmp
[matt@server1 tmp]$ ~/test2.sh
The script you are running has basename test2.sh, dirname /home/matt
The present working directory is /tmp

這是我多年來創造的,用作我的Bash寫作的標題:

## BASE BRAIN - Get where you're from and who you are.
MYPID=$$
ORIGINAL_DIR="$(pwd)" # This is not a hot air balloon ride..
fa="$0" # First Assumption
ta= # Temporary Assumption
wa= # Weighed Assumption
while true; do
    [ "${fa:0:1}" = "/" ] && wa=$0 && break
    [ "${fa:0:2}" = "./" ] && ta="${ORIGINAL_DIR}/${fa:2}" && [ -e "$ta" ] && wa="$ta" && break
    ta="${ORIGINAL_DIR}/${fa}" && [ -e "$ta" ] && wa="$ta" && break
done
SW="$wa"
SWDIR="$(dirname "$wa")"
SWBIN="$(basename "$wa")"
unset ta fa wa
( [ ! -e "$SWDIR/$SWBIN" ] || [ -z "$SW" ] ) && echo "I could not find my way around :( possible bug in the TOP script" && exit 1

此时此刻,您的变量 SW、SWDIR 和 SWBIN 包含您需要的内容。

$0 不是一个可靠的方式来获得当前的脚本路径. 例如,这是我的.xprofile:

#!/bin/bash
echo "$0 $1 $2"
echo "${BASH_SOURCE[0]}"
# $dir/my_script.sh &

cd /tmp && ~/.xprofile && 来源 ~/.xprofile

/home/puchuu/.xprofile
/home/puchuu/.xprofile
-bash
/home/puchuu/.xprofile

因此,请使用 BASH_SURCE 代替。

這是解決方案 e-satis 和 3bcdnlklvc04a 在他們的答案中指出的輕微改訂:

SCRIPT_DIR=''
pushd "$(dirname "$(readlink -f "$BASH_SOURCE")")" > /dev/null && {
    SCRIPT_DIR="$PWD"
    popd > /dev/null
}

这应该在他们列出的所有情况下仍然有效。

这将防止一个失败的冲动之后的Popd. 感谢控制台。
