和
Get-Content [filename] | Select-Object -Last 10
对我来说,第一种选择是不允许的,第二种选择很慢.有谁知道 PowerShell 的 tail 的有效实现.
For me, it is not allowed to use the first alternative, and the second alternative is slow. Does anyone know of an efficient implementation of tail for PowerShell.
推荐答案
将 -wait
参数与 Get-Content 一起使用,这会显示添加到文件中的行.此功能出现在 PowerShell v1 中,但由于某些原因在 v2 中没有很好地记录.
Use the -wait
parameter with Get-Content, which displays lines as they are added to the file. This feature was present in PowerShell v1, but for some reason not documented well in v2.
这是一个例子
Get-Content -Path "C:\scripts\test.txt" -Wait
运行后,更新并保存文件,您将在控制台上看到更改.
Once you run this, update and save the file and you will see the changes on the console.
