This will take a .txt file and insert :
at position 2 & 10 on every line and output it to a .txt file. 这将获取一个.txt文件,并在每行的2和10位置插入
:
,然后将其输出到.txt文件。
Get-Content -Path C:\YourTextFile.txt `
| ForEach-Object { $_.Insert(2,":").Insert(11,":") } `
| Out-File -FilePath C:\YourOutPutFile.txt -Append
Use a regular expression: 使用正则表达式:
(Get-Content 'C:\path\to\input.txt') -replace '^(.{2})(.{8})', '$1:$2:' |
Set-Content 'C:\path\to\output.txt'
^(.{2})(.{8})
matches the first 2 and the next 8 characters at the beginning of a string ( ^
), and captures them in two groups, so they can be referenced as $1
and $2
in the replacement. ^(.{2})(.{8})
匹配字符串( ^
)开头的前2个字符和后8个字符,并将它们捕获为两组,因此可以在字符串中将它们分别称为$1
和$2
。替代。
