我在solaris上尝试了以下命令但失败了：

错误输出：

wladmin@remhost:$ sed -n '/<Resource/{:a; N; /DB01/!ba; s/.*password="\([^"]*\)".*/\1/p}' /web/bea_apps/perf/Tomcat_Home_v9.0.56/TomcatNode01/conf/server.xml
Label too long: /<Resource/{:a; N; /DB01/!ba; s/.*password="\([^"]*\)".*/\1/p}

期望的结果：

        VEL_CAN_WEB_USER
        host36db06v.mybank.com:1521:DB01

我最终会将解决方案交给ansible。

请协助。

列出 zip 文件的内容如下：

wladmin@solarishost:/tmp$ unzip -l -q /tmp/package-391.zip | awk '{ print $4 }' | sed -n '3,$p' | grep -v '^$'
myapp/src/stage/bras.war
myapp-configuration/src/config/dev/bras.war
myapp-configuration/src/config/dev/deployfiles/acid.properties
myapp-configuration/src/config/perf/deployfiles/acid.properties
myapp-configuration/src/config/prod/deployfiles/acid.properties
myapp-configuration/src/config/qa/deployfiles/acid.properties
myapp-configuration/src/config/uat/deployfiles/acid.properties

从上面我希望通过获取所有具有deployfile和不具有的文件名来创建删除文件列表DEV，我可以使用下面的方法来做到这一点。

wladmin@solarishost:/tmp$ unzip -l -q /tmp/package-391.zip | awk '{ print $4 }' | sed -n '3,$p' | grep -v '^$' | grep deployfiles | grep -v -i DEV
myapp-configuration/src/config/perf/deployfiles/acid.properties
myapp-configuration/src/config/prod/deployfiles/acid.properties
myapp-configuration/src/config/qa/deployfiles/acid.properties
myapp-configuration/src/config/uat/deployfiles/acid.properties

从剩下的东西即

myapp/src/stage/bras.war
myapp-configuration/src/config/dev/bras.war
myapp-configuration/src/config/dev/deployfiles/acid.properties

从剩余的输出中，我希望获得任何出现多次的文件名，即

myapp-configuration/src/config/dev/bras.war

并将其添加到删除文件列表中

最终期望的输出：

myapp-configuration/src/config/perf/deployfiles/acid.properties
myapp-configuration/src/config/prod/deployfiles/acid.properties
myapp-configuration/src/config/qa/deployfiles/acid.properties
myapp-configuration/src/config/uat/deployfiles/acid.properties
myapp-configuration/src/config/dev/bras.war

最终目标是我将使用最终所需的输出列表从 zip 中删除这些文件并仅使用以下 2 个文件重建 zip：

myapp/src/stage/bras.war
myapp-configuration/src/config/dev/deployfiles/acid.properties

请建议。

crontab -l

####Cron to auto restart MYAPP
###*/15 * * * * ansible-playbook  /web/playbooks/detectMYAPP/va_action.yml | tee -a /web/playbooks/detectMYAPP/cron.out

sed -i '/^#.*MYAPP/Is/^[#]*//' /web/playbooks/cronenabledisable/wladmin.cron
crontab /web/playbooks/cronenabledisable/wladmin.cron

不幸的是，它取消了注释部分的注释，即####Cron to auto restart MYAPP无法安装 cron。

有问题的电流输出：

预期输出：

####Cron to auto restart MYAPP
*/15 * * * * ansible-playbook  /web/playbooks/detectMYAPP/va_action.yml | tee -a /web/playbooks/detectMYAPP/cron.out

注意：我希望保留MYAPP在评论部分 ie####Cron to auto restart MYAPP并且我不能为了命名约定而简单地删除它

我希望结合以下两个命令：

ps -ef| grep -v grep|grep java | awk ' {print "PID is:" $2}';

下面的 rsync 工作并帮助将远程目录复制到本地主机

我的问题只是我试图解决的一个更大问题的一小部分。

该问题始于rsync非常复杂且由 ansible 构建且不起作用的命令......此处报告：

它复制的是远程是一个文件，但如果远程是一个目录则失败。

你能建议吗？

下面的 sed 命令有助于将文本添加Hello到输入的每一行的末尾

<complex_query> | sed "s,$,Hello,"
Output:
myvar1: Hello
myvar2: Hello

我现在希望输出grep wow data.txt | cut -d: -f2代替Hello

这怎么可能？

以下是我尝试过但不起作用的东西。

<complex_query> | sed "s,$,(grep wow data.txt  | cut -d: -f2),"

预期的期望输出：

myvar1: <output of grep wow data.txt  | cut -d: -f2 command>
myvar2: <output of grep wow data.txt  | cut -d: -f2 command>

我使用 vi 编辑器修改了一个UTF-8编码的 xml 文件并保存了它。

我在 Redhat Linux 7.9

我检查了更改后的文件编码，发现它是us-ascii

file --mime-encoding tmpfiles/08/config/jdbc/jdbc.xml
tmpfiles/08/config/jdbc/jdbc.xml: us-ascii

我决定将编码改回UTF-8使用以下命令：

iconv -f us-ascii -t UTF-8 tmpfiles/08/config/jdbc/jdbc.xml >tmpfiles/08/config/jdbc/jdbc.xmlenc

echo $?
0

但是，新文件的编码jdbc.xmlenc并未更改为UTF-8并保持不变。请参阅下面的输出：

file --mime-encoding tmpfiles/08/config/jdbc/jdbc.xmlenc
tmpfiles/08/config/jdbc/jdbc.xmlenc: us-ascii

您能否建议我如何将文件编码更改为UTF-8？

以下是示例文件内容：

猫样本.txt

-server -XX:+UseParallelGC -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+AggressiveHeap -XX:+PrintHeapAtGC -Djava.util.logging.FileHandler.limit=12908998 -XX:ParallelGCThreads=4 -Xms1536m -Xmx1536m -Xmn512m -Xss4m -XX:LargePageSizeInBytes=4m -XX:-BindGCTaskThreadsToCPUs -XX:PermSize=256m -XX:MaxPermSize=512m -XX:MaxTenuringThreshold=3 -XX:SurvivorRatio=20 -Dweblogic.SocketReaders=10

在一个单独的映射文件中，我得到了一个字符串列表，其中一个是-Djava.util.logging.FileHandler.limit. 如果找到此字符串，则应将其连同其值一起删除。

因此，我希望删除整个条目（连同它的值）-Djava.util.logging.FileHandler.limit=12908998

我可以-Djava.util.logging.FileHandler.limit通过替换-Djava.util.logging.FileHandler.limit为 null 来删除，如下所示：

sed -e s/-Djava.util.logging.FileHandler.limit//g -i sample.txt

由于正则表达式\S*\s让我尝试了用空格分隔的整个字符串，但以下尝试失败了：

sed -e s/-Djava.util.logging.FileHandler.limit\S*\s//g -i sample.txt

但我不确定如何删除它的价值，即-Djava.util.logging.FileHandler.limit=12908998

期望的输出：

猫样本.txt

-server -XX:+UseParallelGC -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+AggressiveHeap -XX:+PrintHeapAtGC -XX:ParallelGCThreads=4 -Xms1536m -Xmx1536m -Xmn512m -Xss4m -XX:LargePageSizeInBytes=4m -XX:-BindGCTaskThreadsToCPUs -XX:PermSize=256m -XX:MaxPermSize=512m -XX:MaxTenuringThreshold=3 -XX:SurvivorRatio=20 -Dweblogic.SocketReaders=10

我有一个有几行的文件。

我希望更新文件，同时确保文件每一行的最后一个可见字符是单引号'。如果没有，那么我们应该在每行的末尾添加单引号。

如果单引号是一行中的最后一个字符，则保持原样。

猫测试.txt

fahsjhjkhkjhjhajkhjf
afasfsfsfffsfasf'
aaffa' sfff
wfafsfsaffs'
fsafsfs'afffafsasf

预期输出：

fahsjhjkhkjhjhajkhjf'
afasfsfsfffsfasf'
aaffa' sfff'
wfafsfsaffs'
fsafsfs'afffafsasf'

我想要一个非 perl 解决方案，我应该能够'在文件的最后一个可见（非转义字符）行附加一个单引号并将其保存回文件。

猫示例.txt

var1: 'funn'
var2: 'weee'
var3: 'youuuu

   

预期产出

猫示例.txt

var1: 'funn'
var2: 'weee'
var3: 'youuuu'

我知道如何使用打印最后一行awk以及如何在每行末尾附加一个字符，但无法通过仅将单引号附加到最后一行并更新文件来更新文件。

我有一个文件，其条目key: value格式如下：

猫数据.txt

name: 'tom'
tom_age: '31'
status_tom_mar: 'yes'
school: 'anne'
fd_year_anne: '1987'
name: 'hmz'
hmz_age: '21'
status_hmz_mar: 'no'
school: 'svp'
fd_year_svp: '1982'
name: 'toli'
toli_age: '41'

同样...

我只需要查找并打印那些key: value具有重复键的单个条目。

下面的代码让我得到了重复的键

cat data.txt | awk '{ print $1 }' | sort  | uniq -d
name:
school:

但是，我想要在一行中连接重复键的值的输出。

预期输出：

name: ['tom', 'hmz', 'toli']
school: ['anne', 'svp']
tom_age: '31'
status_tom_mar: 'yes'
fd_year_anne: '1987'
hmz_age: '21'
status_hmz_mar: 'no'
fd_year_svp: '1982'
toli_age: '41'

你能建议吗？

我知道如何替换字符串；例如，将文件中的连字符替换为下划线。

但是，对于给定文件中尖括号内的所有文本，我希望用下划线替换所有连字符。

例如，下面的文件：

<charset-params> 
    <input-charset> 
        <resource-path>/*</resource-path> 
        <java-charset-name>UTF-8</java-charset-name> 
    </input-charset> 
</charset-params>

应改为：

<charset_params> 
    <input_charset> 
        <resource_path>/*</resource_path> 
        <java_charset_name>UTF-8</java_charset_name> 
    </input_charset> 
</charset_params>

请注意，UTF-8它没有改变，因为它不在尖括号内。我怎样才能做到这一点？

我可以在本地远程登录到 mysql 进程，如下所示：

我还通过bind-address = 0.0.0.0如下设置确保 MySQL 进程正在侦听所有 IP：

root@localhost:~# netstat -plutn | grep mysql
tcp        0      0 0.0.0.0:33060           0.0.0.0:*               LISTEN      39288/mysqld
tcp        0      0 0.0.0.0:7306            0.0.0.0:*               LISTEN      39288/mysqld

和

root@localhost:~# telnet 82.165.32.59 7306
Trying 82.165.32.59...
Connected to 82.165.32.59.
Escape character is '^]'.
>Host 'linux' is not allowed to connect to this MySQL serverConnection closed by foreign host

我打开防火墙端口 7306 并使用以下命令重新加载防火墙：

root@localhost:~# firewall-cmd --zone=public --permanent --add-port=7306/tcp
Warning: ALREADY_ENABLED: 7306:tcp
success
root@localhost:~#  firewall-cmd --reload
success
root@localhost:~# firewall-cmd --list-all

  ports: 443/tcp 80/tcp 7306/tcp
  protocols:
  masquerade: no
  forward-ports:
  source-ports:
  icmp-blocks:
  rich rules:

但是，当从远程主机 telnet 失败时，如下所示：

$ telnet 82.165.32.59 7306
Trying 82.165.32.59...

telnet: connect to address 82.165.32.59: Connection timed out

我的操作系统是：

root@localhost:~# uname -a
Linux localhost 5.4.0-89-generic #100-Ubuntu SMP Fri Sep 24 14:50:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

我尝试重新启动防火墙服务，如下所示：

root@localhost:~# systemctl restart firewalld

我还使用以下脚本刷新了 IPTABLES，但没有帮助：

root@localhost:~# cat fw.stop
#!/bin/sh
echo "Stopping IPv4 firewall and allowing everyone..."
ipt="/sbin/iptables"
## Failsafe - die if /sbin/iptables not found
[ ! -x "$ipt" ] && { echo "$0: \"${ipt}\" command not found."; exit 1; }
$ipt -P INPUT ACCEPT
$ipt -P FORWARD ACCEPT
$ipt -P OUTPUT ACCEPT
$ipt -F
$ipt -X
$ipt -t nat -F
$ipt -t nat -X
$ipt -t mangle -F
$ipt -t mangle -X
$ipt -t raw -F
$ipt -t raw -X

我还使用以下网站检查了端口 7306 是否对外界开放，但它也说Port 7306 is closed on 82.165.32.59.

然而，下面是输出iptables -L，我没有理解它的专业知识。
