我正在尝试在Ubuntu中编写一个极其简单的脚本,它将允许我传递它一个文件名或目录,并且能够在它是一个文件时做一些特定的事情,当它是一个目录时做一些其他的事情。我遇到的问题是,当目录名,或可能文件,有空格或其他可转义字符在名称中。

下面是我的基本代码,还有几个测试。

#!/bin/bash

PASSED=$1

if [ -d "${PASSED}" ] ; then
    echo "$PASSED is a directory";
else
    if [ -f "${PASSED}" ]; then
        echo "${PASSED} is a file";
    else
        echo "${PASSED} is not valid";
        exit 1
    fi
fi

这是输出:

andy@server~ $ ./scripts/testmove.sh /home/andy/
/home/andy/ is a directory

andy@server~ $ ./scripts/testmove.sh /home/andy/blah.txt
/home/andy/blah.txt is a file

andy@server~ $ ./scripts/testmove.sh /home/andy/blah\ with\ a\ space.txt
/home/andy/blah with a space.txt is not valid

andy@server~ $ ./scripts/testmove.sh /home/andy\ with\ a\ space/
/home/andy with a space/ is not valid

所有这些路径都是有效的,并且存在。

if test -f $filename                                                                                      
then                                                                                                      
        echo "this is a file"                                                                             
else

fi 

在/bin/test上使用-f和-d开关:

F_NAME="${1}"

if test -f "${F_NAME}"
then                                   
   echo "${F_NAME} is a file"
elif test -d "${F_NAME}"
then
   echo "${F_NAME} is a directory"
else                                   
   echo "${F_NAME} is not valid"
fi

更优雅的解决方案

echo "Enter the file name"
read x
if [ -f $x ]
then
    echo "This is a regular file"
else
    echo "This is a directory"
fi

一个衬套

touch bob; test -d bob && echo 'dir' || (test -f bob && echo 'file')

结果为真(0)(dir)或真(0)(file)或假(1)(两者都不是)

这应该可以工作:

#!/bin/bash

echo "Enter your Path:"
read a

if [[ -d $a ]]; then 
    echo "$a is a Dir" 
elif [[ -f $a ]]; then 
    echo "$a is the File" 
else 
    echo "Invalid path" 
fi
