对于tcsh，您可以使用:h变量修饰符来检索路径。

需要注意的是，如果脚本作为tcsh myscript执行。Csh，那么您将只获得脚本名称。一个解决方法是验证路径，如下所示。

#!/bin/tcsh

set SCRIPT_PATH = $0:h
if ( $SCRIPT_PATH == $0 ) then
        set SCRIPT_PATH = "."
endif

$SCRIPT_PATH/compile.csh > $SCRIPT_PATH/results.txt

这应该能奏效:

echo `pwd`/`dirname $0`

它可能看起来很丑，这取决于它是如何被调用和cwd，但应该得到你需要去的地方(或者你可以调整字符串，如果你关心它的外观)。

So many answers, all plausible, each with pro's and con's & slightly differeing objectives (which should probably be stated for each). Here's another solution that meets a primary objective of both being clear and working across all systems, on all bash (no assumptions about bash versions, or readlink or pwd options), and reasonably does what you'd expect to happen (eg, resolving symlinks is an interesting problem, but isn't usually what you actually want), handle edge cases like spaces in paths, etc., ignores any errors and uses a sane default if there are any issues.

每个组件都存储在一个单独的变量中，您可以单独使用:

# script path, filename, directory
PROG_PATH=${BASH_SOURCE[0]}      # this script's name
PROG_NAME=${PROG_PATH##*/}       # basename of script (strip path)
PROG_DIR="$(cd "$(dirname "${PROG_PATH:-$PWD}")" 2>/dev/null 1>&2 && pwd)"

cd $(dirname $(readlink -f $0))

灵感来自blueyed的回答

read < <(readlink -f $0 | xargs dirname)
cd $REPLY

基本版:

dir=$(dirname $0)

如果脚本可以通过$PATH调用，那么:

dir=$(dirname $(which $0))

如果脚本可能像这样调用:bash script.sh，那么:

dir=$(dirname $(which $0 2>/dev/null || realpath ./$0))

如果你感到极度不安全，那么:

dir="$(dirname -- "$(which -- "$0" 2>/dev/null || realpath -- "./$0")")"
