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}

我发现最简单的方法是:

for i in `ls`; do echo "`pwd`/$i"; done

这对我来说很有效。

这适用于Linux和Mac OSX:

echo $(pwd)$/$(ls file.txt)

适用于Mac, Linux， *nix:

这将为您提供当前目录下所有文件的引用csv:

ls | xargs -I {} echo "$(pwd -P)/{}" | xargs | sed 's/ /","/g'

输出可以很容易地复制到python列表或任何类似的数据结构中。

除了"readlink -f"，还有一个常用的命令:

$find /the/long/path/but/I/can/use/TAB/to/auto/it/to/ -name myfile /the/long/path/but/I/can/use/TAB/to/auto/it/to/myfile $

这也给出了控制台的完整路径和文件名

跑题:这种方法只给出相对链接，而不是绝对链接。readlink -f命令是正确的。

使用指向:

readlink -f file.txt
