Retrieve text from a file in ps script - powershell

Question

I have a text file containing some data as follows:
test|wdthe$muce
check|muce6um#%
How can I check for a particular string like test and retrieve the text after the | symbol to a variable in a PowerShell script?
And also,
If Suppose there is variable $from=test#abc.com and how to search the file by splitting the text before "#" ?

Answer 1

this may be one possible solution
$filecontents = #'
test|wdthe$muce
check|muce6um#%
'#.split("`n")
# instead of the above, you would use this with the path of the file
# $filecontents = get-content 'c:\temp\file.txt'
$hash = #{}
$filecontents | ? {$_ -notmatch '^(?:\s+)?$'} | % {
$split = $_.Split('|')
$hash.Add($split[0], $split[1])
}
$result = [pscustomobject]$hash
$result
# and to get just what is inside 'test'
$result.test
*note: this may only work if there is only one of each line in the file. if you get an error, try this other method
$search = 'test'
$filecontents | ? {$_ -match "^$search\|"} | % {
$_.split('|')[1]
}

Answer 2

First you need to read the text from the file.
$content = Get-Content "c:\temp\myfile.txt"
Then you want to grab the post-pipe portion of each matching line.
$postPipePortion = $content | Foreach-Object {$_.Substring($_.IndexOf("|") + 1)}
And because it's PowerShell you could also daisy-chain it together instead of using variables:
Get-Content "C:\temp\myfile.txt" | Foreach-Object {$_.Substring($_.IndexOf("|") + 1)}
The above assumes that you happen to know every line will include a | character. If this is not the case, you need to select out only the lines that do have the character, like this:
Get-Content "C:\temp\myfile.txt" | Select-String "|" | Foreach-Object {$_.Line.Substring($_.Line.IndexOf("|") + 1)}
(You need to use the $_.Line instead of just $_ now because Select-String returns MatchInfo objects rather than strings.)
Hope that helps. Good luck.

gc input.txt |? {$_ -match '^test'} |% { $_.split('|') | select -Index 1 }
or
sls '^test' -Path input.txt |% { $_.Line.Split('|') | select -Index 1 }
or
sls '^test' input.txt |% { $_ -split '\|' | select -Ind 1 }
or
(gc input.txt).Where{$_ -match '^test'} -replace '.*\|'
or
# Borrowing #Anthony Stringer's answer shape, but different
# code, and guessing names for what you're doing:
$users = #{}
Get-Content .\input.txt | ForEach {
if ($_ -match "(?<user>.*)\|(?<pwd>.*)") {
$users[$matches.user]=$matches.pwd
}
}
$users = [pscustomobject]$users
