我声明了一个变量： username=user2
测试json内容如下： { "name": "user1", "city": "Texas" }
我想用变量用户名替换 name 的值，即 user1 我尝试了以下命令： sed -i 's/"name": "user1"/"name": $username/g'
输出是：
{“名称”：$用户名，“城市”：“德克萨斯州”}
预期输出为：
{“名称”：“user2”，“城市”：“德克萨斯州”}
如何才能实现这一目标？提前致谢
我正在尝试从此 Youtube 文件名中删除表情符号：
وسائل الاتصال الحديث٩ٌ ? & ? ? -eYrBcHOx2Jf.mp4
我正在使用perl -p -e 's/[^[:ascii:]]//g'但tr -dc '[:print:]'得到了这个；
&-eYrBcHOx2Jf.mp4
如何删除表情并保留阿拉伯字符？
我有一些文件需要清理一些名称。
例如：
GCA_940670685.1_Clostridium_sp_chr 3757330
GCA_940677205.1_Clostridium_colinum_chr 2035557

GCA_943169635.1_Fenollaria_sp_chr 3260126
GCA_943169825.1_Varibaculum_sp_chr 4423380
GCA_943736995.1_Sporosarcina_sp_chr 3771420
我需要一些这样的：
GCA_940670685.1 3757330
GCA_940677205.1 2035557
GCA_942548115.1 3463989
GCA_943169635.1 3260126
GCA_943169825.1 4423380
GCA_943736995.1 3771420
我尝试使用：
sed 's/_[A-Za-z]+_//gI' Terrabacteria_chr_lengths.tsv
sed 's/\w+_\w+_chr//gI' Terrabacteria_chr_lengths.tsv
find Results/Lengths/Bacteria -type f -exec sed -i 's/_\w+_\w+_chr//g' {} \;
但似乎没有任何效果，我认为由于我在正则表达式方面的技能不佳，例如。\w+ \w+_chr。
任何建议将不胜感激。谢谢你。
保罗
我想将文件中的一行替换为包含“某事某事”的另一行。我尝试通过 sed 并使用反斜杠来实现这一点，但它没有用。我尝试了 's/original/'something something'' 我在每个 (') 之前插入了一个反斜杠，但它不起作用。
任何想法？如果我无法使用 sed 实现这一点，我很乐意尝试不同的工具。
我只是想知道如何使用 sed 提取特定列？（我的系统已经安装了 sed，所以不幸的是没有 awk :(）。我得到了一个如下文本文件：

文件中有很多行还有更多行，但我猜这已经足够了。现在我需要提取 Business Name 列中的信息。所以我尝试了：
sed -n '^[^,]*,{1}p' $1
其中 $1 是从用户输入读取的文件名。我也试过：
sed -n '\^\[\^,\]*,{1}p' $1
我更熟悉 grep RE，这就是为什么它们看起来像 grep RE 而不是 sed 的原因。最近才开始使用 sed。
我需要输入cat温度值/sys/class/hwmon/hwmon[0-9]/temp[0-9]_input并将它们附加到给定文件中的相应名称。
帮助 ！
我使用 sed 显示文件 'sed.txt' 的前 2 行，但它不起作用：文件 sed.txt 就像：
$cat sed.txt
1
2
3
4
使用 sed 命令：
$sed -e '1,2p' sed.txt
1
1
2
2
3
4
第 3 行和第 4 行也打印出来了，为什么？
作为我的 Bash 服务器设置脚本的一部分，我试图锁定默认的 apache www 网站。
我想转换这个：
<Directory /var/www>
Options Indexes FollowSymLinks
对此：
<Directory /var/www>
Options -Indexes -FollowSymLinks -ExecCGI
由于Options Indexes FollowSymLinks在文件中多次提到，我需要搜索和替换以包含上一行。
我尝试了以下sed命令，使用反斜杠来转义斜杠，但它不会替换任何内容：
cat /etc/apache2/apache2.conf | sed 's/[<Directory \/var\/www\/>]\n Options Indexes FollowSymLinks/[<Directory \/var\/www\/>]\n Options -Indexes -FollowSymLinks -ExecCGI/;P;D'
我试过把东西放在引号和方括号里。该命令似乎也不喜欢这些选项卡。
任何想法，将不胜感激。
我有一个包含如下数据的文件。xyz可以是任何东西，所以我想替换它。
variable "azure_spoke_gateways" {
default = {
spoke1 = {
name = "xyz"
size = "max"
vpc = "azure_spoke1_vnet"
},
}
}
variable "google_spoke_gateways" {
default = {
spoke1 = {
name = "xyz"
size = "max"
vpc = "azure_spoke1_vnet"
},
}
}
我只想替换variable azure_spoke_gateways's 的值name。所需的输出是：
variable "azure_spoke_gateways" {
default = {
spoke1 = {
name = "MYSTRING"
size = "max"
vpc = "azure_spoke1_vnet"
},
}
}
好的，考虑这个示例文件：
#!/usr/bin/env bash
cat > example_file.txt <<EOL
group, , price
1, S_BRN_, 3.21
1, S_WBS_BRN_, 4.11
1, S_WBS_BRN, 1.22
2, S_BRN_WBS, 9.2
2, F_WBS_BRN_, 2.11
2, F_BRN_, 2.11
2, F_BRN_WBS_, 2.11
EOL
我想要所有包含字符串“F_BRN_”或“S_BRN_”的行。我执行以下 sed：
sed -n '/S_BRN_\|F_BRN_/p' example_file.txt
我得到：
1, S_BRN_, 3.21
1, S_WBS_BRN_, 4.11
2, S_BRN_WBS, 9.2
2, F_WBS_BRN_, 2.11
2, F_BRN_, 2.11
2, F_BRN_WBS_, 2.11
我的问题是：如何防止部分匹配？例如 F_WBS_BRN_ 不包含子字符串 F_BRN_，因此不应返回它。
