如何获得文件的完整路径?

是否有一种简单的方法可以打印file.txt的完整路径?

file.txt = /nfs/an/disks/jj/home/dir/file.txt

<命令>

dir> <command> file.txt

应该打印

/nfs/an/disks/jj/home/dir/file.txt

当前回答

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

这将为您提供文件的绝对路径:

find / -name file.txt

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}

创建一个如下所示的函数(使用pwd回显文件的绝对路径，并将文件添加到路径的末尾:
