當(dāng)你分析文本日志或篩選不通類型的信息時(shí)，你通常要使用 Where-Object。這里有一個(gè)通用腳本來(lái)說(shuō)明復(fù)合篩選：
# logical AND filter for ALL keywords
Get-Content -Path C:\windows\WindowsUpdate.log |
Where-Object { $_ -like '*successfully installed*' } |
Where-Object { $_ -like '*framework*' } |
Out-GridView
# above example can also be written in one line
# by using the -and operator
# the resulting code is NOT faster, though, just harder to read
Get-Content -Path C:\windows\WindowsUpdate.log |
Where-Object { ($_ -like '*successfully installed*') -and ($_ -like '*framework*') } |
Out-GridView
# logical -or (either condition is met) can only be applied in one line
Get-Content -Path C:\windows\WindowsUpdate.log |
Where-Object { ($_ -like '*successfully installed*') -or ($_ -like '*framework*') } |
Out-GridView
