powershell basic syntax question for select
Question
Background: Here the goal is to do some basic commands in powershell using select-string. For some reason, there are certain things that are not working as expected.
Assume the following:
$vfilter = 'c:/foo/bar/files/*.htm';
Select-String -path $vfilter -pattern ".*DOCTY.*" |
sort LineNumber |
where-object { $_.Filename -match "02" } |
format-list |
out-file c:/00junk.txt;
... where this is the output ...
IgnoreCase : True
LineNumber : 1
Line : <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "ht
tp://www.w3.org/TR/html4/loose.dtd">
Filename : 02junk.htm
Path : C:\ ... \02junk.htm
Pattern : .*DOCTY.*
Context :
Matches : {<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "h
ttp://www.w3.org/TR/html4/loose.dtd">}
Questions:
1) How can i prevent powershell from wrapping the text of "Line" and "Matches" properties. Since this is being sent to a text file, I do not care about console width and therefore I do not want any text wrapping to occur.
2) Suppose I want to do my own custom output with a multi-line string. In Ruby (for example) I could do it like this:
custom_string = '';
items.each{|myitem|
custom_string += %Q[
### begin output ###
HereIs::LineNumber! --> #{myitem['LineNumber']}
HereIs::Path! --> #{myitem['Path']}
This is the actual line (below):
#{myitem['Line']}
]
}
custom_string.tofile('c:/00junk.txt');
How can I get powershell to do the same or similar thing?
3) How could I do 2) above with a powershell here-string?

1) To prevent wrapping you can specify a huge width parameter for Out-File .
2) Use ForEach-Object (alias % ) to generate your string:
$vfilter = 'c:/foo/bar/files/*.htm';
Select-String -path $vfilter -pattern ".*DOCTY.*" |
sort LineNumber |
where-object { $_.Filename -match "02" } |
ForEach-Object {
@"
Line Number: $($_.LineNumber)
Path: $($_.Path)
This is the actual line (below):
$($_.Line)
"@
} |
out-file c:/00junk.txt;
