我有一堆文件，每个文件都在自己的子目录中。我需要编写一个脚本来重命名每个文件，使其与其目录具有相同的名称：例如，给出：
./1111/1234.pdf
./2222/2345.pdf
./1234/3214.pdf
我需要将它们重命名为：
./1111/1111.pdf
./2222/2222.pdf
./1234/1234.pdf
我怎样才能做到这一点？
我正在尝试与一个不受我管理的系统交互，该系统正在执行一些 Unix 命令脚本和命令以轻松执行作业。
有一个变量替换不起作用，我想知道是否可以编写一个命令来避免这种情况。有很多变量需要设置，我希望有机会输入一个空变量。问题在于系统没有传递空变量并且根本没有设置该变量。我明白了
${option.VARIABLE}：错误替换
我尝试设置类似的东西但不起作用。
if [ -z ${option.VARIABLE} ]; 然后 option.VARIABLE=""; 菲；
任何想法？
我被分配生成一个脚本，该脚本可以禁用 ssh 服务的密码登录。知道我可以通过编辑 /etc/sshd_config 文件来执行此操作，但我的导师提到我应该查看的文件是 /etc/password 文件。这是我执行此任务的提示。这就是我所做的，我删除了用户中的“x”符号。我相信该字段是为散列密码保留的。
原本的
pi:x:1000:1000:,,,:/home/pi:/bin/bash
编辑后：
pi::1000:1000:,,,:/home/pi:/bin/bash
结果：没有密钥，我只能重新输入传递窗口。
为清晰起见更新：该脚本应用于回复公钥和私钥，以便登录 pi 服务器。换句话说，我尝试使用无密码登录，使其成为加强安全性的功能。
我是 bash 脚本的新手，我在命令的聚合方面遇到了问题。正是在这行代码中：
timeout -s 9 1 echo $var | nc localhost port
我正在尝试通过 netcat 将变量 var 的数据发送到特定端口中的 localhost，并且我想将该命令超时 1 秒。阅读 timeout 的手册页我明白它应该被用作：
timeout -s SIGNAL TIME COMMAND
我的问题是如何用管道命令 echo $var | 替换 COMMAND nc localhost 端口并进一步了解如何正确编写以下情况：
COMMAND1 | (COMMAND2 | COMMAND3)
和
(COMMAND1 | COMMAND2) | COMMAND3
如果我是对的，第二个例子相当于
COMMAND1 | COMMAND2 | COMMAND3
但我不知道如何写第一个。
我正在尝试搜索具有 pattern 的文件FW。从这些过滤后的文件中，我试图搜索 pattern chmod.*archive|archive.*chmod，然后列出它们。
我尝试使用以下命令，但它没有给我所需的输出。需要帮助来解决这个问题。
find . -name '*FW*' -exec sh -c "cat {}|grep -iEq 'chmod.*archive|archive.*chmod'|ls" \;|more
我想将内容添加到当前目录中每个文件的开头。我需要学习如何一次从当前工作目录中获取所有文件名并将它们作为参数；我不需要通过手动指定每个文件作为脚本的参数来做到这一点。我想将这些新知识用于进一步的脚本。我不需要横向或不同的解决方案。我需要学习如何获取命令 ( ls) 输出并将其作为参数。我尝试过但失败了：
./file-edit.sh $(ls)
./file-edit.sh `ls`
这是我的脚本，它有效：
#!/bin/bash
lineno=2 # Append from line 2
BAD_ARGS=85 # Error code
string0="###################################################################"
string2="#Description :"
string3="#Date :`date +%d-%B-%Y`"
string4="#Author :Milos Stojanovic"
string5="#Contact: :https://www.linkedin.com/in/xxx/"
string6="###################################################################"
# Can be any other strings
if [ ! -f $1 ]; then
echo "Please specify at least 1 filename as an argument!"
exit $BAD_ARGS
fi
until [ -z "$1" ]
do
string1="#Script Name :$1"
file=$1;
sed -i ""$lineno"i $string0\n$string1\n$string2\n$string3\n$string4\n$string5\n$string6" $file
echo "File "\'$file\'" altered at line …我想编写一个 shell 命令，stdout用空格替换匹配特定正则表达式的所有段落中的所有换行符。在这里，我将一个段落定义为以两个或多个新行结尾的任何文本。
具体来说，我想找到所有不以(or开头的文本段落，$并去除所有换行符的这些段落。
例如，运行我的脚本
Aliquam erat volutpat. Nunc ( eleifend leo vitae magna. In (i)yd erat non orci
commodo lobortis. Proin $ neque massa, cursus ut, gravida ut, lobortis eget,
lacus. Sed diam.
Hello world.
(Nullam tristique diam
non turpis.
Hello
$again!
$foo
bar
应该导致
Aliquam erat volutpat. Nunc ( eleifend leo vitae magna. In (i)yd erat non orci commodo lobortis. Proin $ neque massa, cursus ut, gravida ut, lobortis eget, lacus. Sed …如何检索像smam和这样的终端设置的状态rmam？
原因是我设置rmam的：
tput rmam
在脚本中，然后smam在退出时继续设置：
tput smam
但是如果终端rmam在脚本启动时设置，我不想smam在退出时设置。
如何才能做到这一点？
我想在循环中执行一个命令，直到它以退出代码退出0，所以我尝试了：
$ while/until $?; do $command; done
但until/while似乎只接受布尔值true/false而不是0/1.
我是否错过了类似的[[ ]]东西或其他东西？
我正在编写一个脚本来准备一个包含第 5、6、7、8、10 和 13 列的 csv 文件；取第 44 列上等于 7 的行，同时也满足第 3 列上等于 1 的行。
