you@you:~/test$ ls
file
you@you:~/test$ path="`pwd`/`ls`"
you@you:~/test$ echo $path
/home/you/test/file

这将适用于文件和文件夹:

getAbsolutePath(){
    [[ -d $1 ]] && { cd "$1"; echo "$(pwd -P)"; } || 
    { cd "$(dirname "$1")" || exit 1; echo "$(pwd -P)/$(basename "$1")"; }
}

fp () {
PHYS_DIR=`pwd -P`
RESULT=$PHYS_DIR/$1
echo $RESULT | pbcopy
echo $RESULT
}

将文本复制到剪贴板并在终端窗口上显示文本。

(我从另一个堆栈溢出的答案复制了一些代码，但再也找不到答案了)

我知道这是一个老问题了，但在这里补充一下信息:

Linux命令，可用于查找命令文件的文件路径。

$ which ls
/bin/ls

这里有一些注意事项;请参见https://www.cyberciti.biz/faq/how-do-i-find-the-path-to-a-command-file/。

这很天真，但是我必须使它与POSIX兼容。需要进入文件目录的cd权限。

#!/bin/sh
if [ ${#} = 0 ]; then
  echo "Error: 0 args. need 1" >&2
  exit 1
fi


if [ -d ${1} ]; then


  # Directory


  base=$( cd ${1}; echo ${PWD##*/} )
  dir=$( cd ${1}; echo ${PWD%${base}} )

  if [ ${dir} = / ]; then
    parentPath=${dir}
  else
    parentPath=${dir%/}
  fi

  if [ -z ${base} ] || [ -z ${parentPath} ]; then
    if [ -n ${1} ]; then
      fullPath=$( cd ${1}; echo ${PWD} )
    else
      echo "Error: unsupported scenario 1" >&2
      exit 1
    fi
  fi

elif [ ${1%/*} = ${1} ]; then

  if [ -f ./${1} ]; then


    # File in current directory

    base=$( echo ${1##*/} )
    parentPath=$( echo ${PWD} )

  else
    echo "Error: unsupported scenario 2" >&2
    exit 1
  fi
elif [ -f ${1} ] && [ -d ${1%/*} ]; then


  # File in directory

  base=$( echo ${1##*/} )
  parentPath=$( cd ${1%/*}; echo ${PWD} )

else
  echo "Error: not file or directory" >&2
  exit 1
fi

if [ ${parentPath} = / ]; then
  fullPath=${fullPath:-${parentPath}${base}}
fi

fullPath=${fullPath:-${parentPath}/${base}}

if [ ! -e ${fullPath} ]; then
  echo "Error: does not exist" >&2
  exit 1
fi

echo ${fullPath}

我知道有一个更简单的方法，但如果我能找到它…

jcomeau@intrepid:~$ python -c 'import os; print(os.path.abspath("cat.wav"))'
/home/jcomeau/cat.wav

jcomeau@intrepid:~$ ls $PWD/cat.wav
