如何在 Powershell 中执行 head、tail、more、less、sed 的操作? [英] How to do what head, tail, more, less, sed do in Powershell?

问题描述

在windows上，使用Powershell，linux的head、tail、more、less等价命令有哪些> 和 sed?

解决方案

Get-Content(别名:gc)是读取文本文件的常用选项.然后您可以进一步过滤:

gc log.txt |select -first 10 # 头gc -TotalCount 10 log.txt # 也是头gc 日志.txt |select -last 10 # 尾gc -Tail 10 log.txt # 也是 tail (自 PSv3)，也比上面的选项快得多gc 日志.txt |如果您安装了它，则更多 # 或更少gc 日志.txt |%{ $_ -replace '\d+', '($0)' } # sed

这对于小文件来说已经足够了，大文件(超过几个 MiB)可能有点慢.

PowerShell 社区扩展 包括一些用于专门文件内容(例如 Get-FileTail)的 cmdlet.>

On windows, using Powershell, what are the equivalent commands to linux's head, tail, more, less and sed?

解决方案

Get-Content (alias: gc) is your usual option for reading a text file. You can then filter further:

gc log.txt | select -first 10 # head
gc -TotalCount 10 log.txt     # also head
gc log.txt | select -last 10  # tail
gc -Tail 10 log.txt           # also tail (since PSv3), also much faster than above option
gc log.txt | more             # or less if you have it installed
gc log.txt | %{ $_ -replace '\d+', '($0)' }         # sed

This works well enough for small files, larger ones (more than a few MiB) are probably a bit slow.

The PowerShell Community Extensions include some cmdlets for specialised file stuff (e.g. Get-FileTail).
