PowerShell v2 Pipelining in 73 (make that 53) Characters

PowerShell Team

I started using Twitter and saw a request from Thomas Lee for help about pipelining in CTP3.  The thing about Twitter is that the messages have to be tiny so I wasn’t sure I could answer using it.  It turns out I can solve this problem AND give a usage example in 73 characters.  Here goes:

PS> function t{param([Parameter(ValueFromPipeline=1)]$t);process{$t}};1..10|t
1
2
3
4
5
6
7
8
9
10

Now if you put it into a file (which is actually what Thomas asked for), then it is only 53 characters:

PS> cat t.ps1
param([Parameter(ValueFromPipeline=1)]$t);process{$t}
PS> cat t.ps1 |Measure -Character

Lines              Words                      Characters Property
—–              —–                      ———- ——–
                                                      53

PS> 1..10 |.\t.ps1
1
2
3
4
5
6
7
8
9
10

Enjoy!
