linux – mv包含shell脚本空格的文件

mv "$onam" "$dnam"

基本上,在包含可能包含空格的文件名的变量周围使用引号.但是,除非文件名或目录名本身包含引号,否则这些值本身不应包含引号.

不幸的是,我不能立即想到一个简单的方法来使用像$1这样的值和硬编码的引号.你必须弄乱eval或其他地方.

SSCCE(Short,Self-Contained,Correct Example)

此代码与您显示的代码同构,但实际上更多.运行和清理自己也是安全的.它假设您正在使用bash.请注意,带空格的名称在一行中包含多个空格;如果您尝试使用包含单个空格的名称,很容易被误导为虚假的安全感.

#!/bin/bash
testdir=test.$$
mkdir "$testdir" || exit 1

trap "rm -fr '$testdir'; exit 1" 0 1 2 3 13 15

(
    set -x
    x=$'nn'
    cd test.$$

    basedir="$PWD"
    sub1dir="rename  test"
    sub2dir="Test   Folder"
    subdir="$sub1dir/$sub2dir"

    mkdir -p "$basedir/$subdir"

    oldfile="test   file"

    cp /etc/group "$basedir/$subdir/$oldfile"

    echo "$x"
    ls -lR .

    echo "$x"
    newfile=$(echo "$oldfile" | sed 's/ /-/g')
    mv "$basedir/$subdir/$oldfile" "$basedir/$subdir/$newfile"
    ls -lR .

    echo "$x"
    new2dir=$(echo "$sub2dir" | sed 's/ /-/g')
    mv "$basedir/$subdir"  "$basedir/$sub1dir/$new2dir"

    new1dir=$(echo "$sub1dir" | sed 's/ /-/g')
    mv "$basedir/$sub1dir" "$basedir/$new1dir"

#Ideas?

你必须要小心;请注意我是如何从片段中建立名称并对其进行分解等的.但是要小心,它可以完成.

示例输出

使用bash -x运行,但你可以只用bash运行它,你只需跳过一点输出,因为它在子shell代码中包含一个set -x.
