How to read from input file and pass to script

Question

 How can I get rid of the hard coded PATH statement and feed script based upon text file input.
   Input is contained in a file..
'C:\cntprocess\   called sistemfolder.txt that has 2 fields folder
then shortname.
example:
 C:\cntprocess\REW1___1~Rew1
 C:\cntprocess\REW2___1~Rew2
 I want the first part in each record passed to script for processing
C:\cntprocess\REW1___1
C:\cntprocess\REW2___1
Pass those values to this Script: I want values from above passed to the $Path
$path='C:\Sistemi\'
get-childitem -path $path *.spx | % {
" Starting File Process....." >> $path\sistem.log
$PDate = get-date
$date = get-date -uformat "_%d_%m_%Y_%H%M%S.bak"
#"Set backup date to $date" >> $path\sistem.log
$newname=($_.fullname -replace ".spx",$date)
$file = [System.IO.Path]::GetFileNameWithoutExtension($_.fullname)
"File backup name is $newname" >> $path\sistem.log
Rename-Item $_.fullname $newname
"Renamed file to $newname" >> $path\sistem.log
$lines = get-content $newname
foreach ($line in $lines)
$line + " " + [System.IO.Path]::GetFileNameWithoutExtension($_.fullname) | Out-File "$path\sistem.csv" -append
Write-Host $_.fullname
"Files Processed on $PDate are $newname " >> $path\sistem.log
Thanks.

OK, I was mistaken a bit on what I originally told you. After you run the command of
$myFile = Import-Csv -Delimiter '~' -Path $path -Header Path, ShortName
$myFile is actually an array of PSCustomObjects, so you cannot access it like $myFile.Path, you will actually have to loop through the $myFile first, so try changing your script to be the following and see if that helps any
param
[string]$path
$myFiles = Import-Csv -Delimiter '~' -Path $path -Header Path, ShortName
# Then you can call it like so
$myFiles.Path #Returns just the path
$myFiles.ShortName # Returns the shortname
$path='C:\AreaSistemi1\'
foreach ($myFile in $myFiles)
get-childitem -path $myFile.Path *.spx | % {
" Starting File Process....." >> $myFile.Pathsistem.log
$PDate = get-date
$date = get-date -uformat "_%d_%m_%Y_%H%M%S.bak"
#"Set backup date to $date" >> $path\sistem.log
$newname=($_.fullname -replace ".spx",$date)
$file = [System.IO.Path]::GetFileNameWithoutExtension($_.fullname)
"File backup name is $newname" >> $myFile.Pathsistem.log
Rename-Item $_.fullname $newname
"Renamed file to $newname" >> $myFile.Pathsistem.log
$lines = get-content $newname
foreach ($line in $lines)
$line + " " + $myFile.ShortName | Out-File "$path\sistem.csv" -append
Write-Host $_.fullname
"Files Processed on $PDate are $newname " >> $path\sistem.log
Also looking at your script, you said your text file contained the format of <filePath>~<shortname> but I see you doing a $myFile.Pathisstem.log, where does the Pathisstem.log come from?
