Commands

Cmdlets

  • Select-String (sls): sls <pattern> <path>
  • Measure-Object (measure)
  • ForEach-Object (%)
  • Sort-Object -Unique (sort) ∙∙∙∙∙∙∙ Get-Unique (gu)
  • Out-String -Stream

Examples

$str -Match "<regex>"
$str | sls "<regex>"

sls -Path <./file.txt> -Pattern "<regex>" -CaseSensitive | Measure-Object
    # : Count occurences of <regex> (up to one per line)
sls "<regex>" <path/file> -AllMatches | % {$_.Matches.Value} | measure
    # : Count ALL <regex> in file using -AllMatches and foreach (%)
sls "\(\d{3}\)" ... | % {$_.Matches.Value} | sort -Unique | measure
    # : Count unique area codes in a list of phone numbers

Tips

  • Understand the raw output of each command in the pipeline. Does sls output only the matched text?
