This is an automation of a command to SQLPlus 12c on Linux from Windows 18_3 version on PowerShell 5.1 with Microsoft modules loaded.
I need to clean out the whitespace of the string to input wildcard data on an automation Select script (the final script will find a missing TIFF image and reinsert it).
I am UNABLE to remove the white space before the tee.
The latest attempts are in the post but I have tried Trim, Split, Replace, Remove, Substring, >>, Write-Host -NoNewline,... I am SO close.
When I Write-Host -NoNewline I succeeded in removing the CRLF but not so as I can Tee, Write-Out, or Out-File the content that way.
#Add-Type -AssemblyName System.Data.OracleClient
$filefolder = "C:\EMSCadre\iGateway\clint\Input_Images\"
$Files = Get-ChildItem $FileFolder -Name -File
$longname = $Files.Get(2)
$shortname = $longname.Replace("_tiff","").Replace("cns","").Substring(9).Split('".tif"')
echo "select LD_CASE_NUMBER FROM LOG_data where ld_message_3 like %$shortname%" |
tee -Verbose c:\scripts\input\lockedout_test.sql
type c:\scripts\input\lockedout_test.sql
#Failed attempts
#echo "select LD_CASE_NUMBER FROM LOG_data where ld_message_3 like %($shortname1.TrimEnd('_',"")%" |
# tee -Verbose c:\scripts\input\lockedout_test.sql
Latest Results showing Whitespaces before last %:
select LD_CASE_NUMBER FROM LOG_data where ld_message_3 like %100838953_180130001 %
select LD_CASE_NUMBER FROM LOG_data where ld_message_3 like %100838953_180130001 %
Details to help troubleshoot:
PS C:\scripts> $Files
2823910000.tif
2823910002.tif

exposureworks-dynamic-range-test-f16-graded-TIFF-RGB-parade.jpg
PS C:\scripts> $shortname
100838953_180130001
Looks to me like the last step (Split()) of the statement
$longname.Replace("_tiff","").Replace("cns","").Substring(9).Split('".tif"')
is supposed to remove the extension from the file name. That is not how Split() works. The method interprets the string ".tif" as a character array and splits the given string at any of those characters (", ., f, i, t). Splitting the string 100838953_180130001.tif that way gives you an array with 5 elements, the last 4 of which are empty strings:
[ '100838953_180130001', '', '', '', '' ]
Putting the variable with that array into a string mangles the array into a string by concatenating its elements using the output field separator ($OFS), which by default is a single space, thus producing the trailing spaces you observed.
To remove the prefix cns..._ and the substring _tiff as well as the extension .tif from the file name use the following:
$shortname = $longname -replace '^cns\d*_|_tiff|\.tif$'
That regular expression replacement will remove the substring "cns" followed by any number of digits and an underscore from the beginning of a string (^), the substring "_tiff" from anywhere in a string, and the substring ".tif" from the end of a string ($).

My powershell command below
$BUILD_SOURCEVERSIONMESSAGE= (Get-Item Env:\BUILD_SOURCEVERSIONMESSAGE)
returns output in this format
2018-10-26T01:08:44.7409834Z BUILD_SOURCEVERSIONMESSAGE Merge 569594f057e2c4bd0320159855e81e14216ca66f into 41107d0f0db5ef2986831db2182280e0c...
I am trying to parse the string 569594f057e2c4bd0320159855e81e14216ca66f from the output above.
I tried converting the output to a string, splitting it on whitespace, and accessing the second element of the array as follows. However, I get empty string. How can I access the required string?
echo $BUILD_SOURCEVERSIONMESSAGE
$out = $BUILD_SOURCEVERSIONMESSAGE | Out-String
$out1 = $out.split()
echo $out1[1]
The concise equivalent of command Get-Item Env:\BUILD_SOURCEVERSIONMESSAGE - i.e., retrieving the value of environment variable BUILD_SOURCEVERSIONMESSAGE - is the expression $env:BUILD_SOURCEVERSIONMESSAGE.
Using the unary form of Powershell's -split operator, which splits the input by any nonempty run of whitespace (while stripping leading and trailing whitespace), you can get the desired output as follows:
PS> (-split $env:BUILD_SOURCEVERSIONMESSAGE)[3]
569594f057e2c4bd0320159855e81e14216ca66f
Index 3 extracts the 4th token resulting from the tokenization via -split.
If you want to use string interpolation with the result:
$prefix = 'before<'; $postfix = '>after'
$val = (-split $env:BUILD_SOURCEVERSIONMESSAGE)[3]
# Output a synthesized string that applies a pre- and postfix, using
# {...} to enclose variable names to avoid ambiguity.
"${prefix}${val}${postfix}"
The above yields:
before<569594f057e2c4bd0320159855e81e14216ca66f>after
I have a script I am running in Powershell, and I want to be able to put a line in my resulting text file output between the ccript name and the script content itself.
Currently, from the below, the line $str_msg = $file,[System.IO.File]::ReadAllText($file.FullName) is what I need, but I need a line to separate $file and the result of the next expression. How can I do this?
foreach ($file in [System.IO.Directory]::GetFiles($sqldir,"*.sql",
[System.IO.SearchOption]::AllDirectories))
{
$file = [System.IO.FileInfo]::new($file);
$Log.SetLogDir("");
$str_msg = $file,[System.IO.File]::ReadAllText($file.FullName);
$Log.AddMsg($str_msg);
Write-Output $str_msg;
# ...
}
$str_msg = $file,[System.IO.File]::ReadAllText($file.FullName) doesn't create a string, it creates a 2-element array ([object[]]), composed of the $file [System.IO.FileInfo] instance, and the string with the contents of that file.
Presumably, the .AddMsg() method expects a single string, so PowerShell stringifies the array in order to convert it to a single string; PowerShell stringifies an array by concatenating the elements with a single space as the separator by default; e.g.:
[string] (1, 2) yields '1 2'.
Therefore, it's best to compose $str_msg as a string to begin with, with an explicit newline as the separator, e.g.:
$strMsg = "$file`r`n$([System.IO.File]::ReadAllText($file.FullName))"
Note the use of escape sequence "`r`n" to produce a CRLF, the Windows-specific newline sequence; on Unix-like platforms, you'd use just "`n" (LF).
.NET offers a cross-platform abstraction, [Environment]::NewLine, which returns the platform-appropriate newline sequence (which you could alternatively embed as $([Environment]::NewLine) inside "...").
An alternative to string interpolation is to use -f, the string-formatting operator, which is based on the .NET String.Format() method:
$strMsg = '{0}{1}{2}' -f $file,
[Environment]::NewLine,
[System.IO.File]::ReadAllText($file.FullName)
Backtick-r+backtick-n will do a carriage return with a new line in PS. You could do a Get-Content of your $file variable as a new array variable, and insert the carriage return at a particular index:
Example file: test123.txt
If the file contents were this:
line1
line2
line3
Store the contents in an array variable so you have indices
[Array]$fileContent = Get-Content C:\path\to\test123.txt
To add a carriage return between line2 and line3:
$fileContent2 = $fileContent[0..1] + "`r`n" + $fileContent[2]
Then output a new file:
$fileContent2 | Out-File -FilePath C:\path\to\newfile.txt
You need to use the carriage return powershell special character, which is "`r".
Use it like this to add a carriage return in your line :
$str_msg = $file,"`r",[System.IO.File]::ReadAllText($file.FullName);

For example, how can I change multiple file names in a folder: which are in the format " New file " to "New file" in windows 10 using powershell
From https://blogs.technet.microsoft.com/heyscriptingguy/2014/07/18/trim-your-strings-with-powershell/
The easiest Trim method to use is the Trim() method. It is very useful, and it is the method I use most. It easily removes all whitespace characters from the beginning and from the end of a string. This is shown here:
PS C:\> $string = " a String "
PS C:\> $string.Trim()
# => a String
The method is that easy to use. I just call Trim() on any string, and it will clean it up. Unfortunately, the previous output is a bit hard to understand, so let me try a different approach. This time, I obtain the length of the string before I trim it, and I save the resulting string following the trim operation back into a variable. I then obtain the length of the string a second time. Here is the command:
$string = " a String "
$string.Length
# => 10
$string = $string.Trim()
$string
# => a String
$string.Length
# => 8
try this :
Get-ChildItem "C:\Temp" -Recurse -file | Rename-Item -NewName {"{0}{1}" -f $_.BaseName.Trim(), $_.Extension}
Last week I have asked you guys to replace a string with newline character with .bat script. I have realized that my file has some carriage return and newline characters already, which I need to remove first and then do the replace.
to replace '#####' with linefeed I am using the line below.
(gc $Source) -replace "#####", "`r`n"|set-content $Destination
So I tried to implement the same logic to replace \r and \n as well, however it did not work.
(gc $Source) -replace "`n", ""|set-content $Destination
my file looks like :
abc|d ef|123#####xyz|tuv|567#####
and I need to make it look like
abc|def|123 xyz|tuv|567
like I said, replacing the row delimiter character with new line works, but I need to remove all cr and lf characters first before I do that.
For small files the script below works, but my file is >1.5GB and it throws OutofMemoryException error
param
(
[string]$Source,
[string]$Destination
)
echo $Source
echo $Destination
$Writer = New-Object IO.StreamWriter $Destination
$Writer.Write( [String]::Join("", $(Get-Content $Source)) )
$Writer.Close()
Use the below function to remove the special characters. Put all of them in $SpecChars what ever you want to remove and call the function with the Text-data as a parameter.
Function Convert-ToFriendlyName
{param ($Text)
# Unwanted characters (includes spaces and '-') converted to a regex:
#Whatever characters you want to remove, put it here with comma separation.
$SpecChars = '\', ' ','\\','-'
$remspecchars = [string]::join('|', ($SpecChars | % {[regex]::escape($_)}))
# Convert the text given to correct naming format (Uppercase)
$name = (Get-Culture).textinfo.totitlecase(“$Text”.tolower())
# Remove unwanted characters
$name = $name -replace $remspecchars, ""
$name
}
Hope it helps...!!!
This is vbscript. Windows isn't consistent. Mostly it breaks on CR and removes LF (all inbuilt programming languages). But Edit controls (ie Notepad) break on LF and ignore CR (unless preceding a LF).
Set Inp = WScript.Stdin
Set Outp = Wscript.Stdout
Do Until Inp.AtEndOfStream
Text = Inp.readall
Text = Replace(Text, vbcr, "")
Text = Replace(Text, vblf, "")
Text = Replace(Text, "#####", vblf)
outp.write Text
Loop
This uses redirection of StdIn and StdOut.
Filtering the output of a command

Filtering a file
Cscript //nologo script.vbs < InputFile.txt > OutputFile.txt
See my CMD Cheat Sheet about the Windows' command line Command to run a .bat file
So this removes line ending in win.ini and prints to screen the now one line win.ini.
cscript //nologo "C:\Users\David Candy\Desktop\Replace.vbs" < C:\windows\win.ini
I have the following code
$scriptpath = "C:\Test"
$scriptname = "mount.bat"
$myimage = Read-Host 'Enter the file name of your image'
if (Test-Path $scriptpath\$scriptname) {
Remove-Item $scriptpath\$scriptname
}
Add-Content $scriptpath\$scriptname ':Loop 'n "C:\Program
Files\file.exe" -f \\host\"Shared Folders"\$myimage -m V: `n if not
%errorlevel% equal 0 goto :Loop'
I can't get powershell to output the variable correctly in the output batch file it just says "$myimage" and not the file name. I have tried using the break ` ' symbols but no luck. I also cannot get powershell to export onto a separate line. If anyone could help that would be great.
Since you're using (a) variable references ($myimage) and (b) escape sequences such as `n (to represent a newline) in your string, you must use double quotes to get the expected result.
(Single-quoted strings treat their contents literally - no interpolation takes place.[1])
Furthermore, since your string has embedded double quotes, they must be escaped as `"
Here's a fixed version; note that I've used actual line breaks for readability (rather than `n escape sequences in a single-line string):
$myImage = 'test.png'
":Loop
`"C:\ProgramFiles\file.exe`" -f \\host\`"Shared Folders`"\$myimage -m V:
if not %errorlevel% equal 0 goto :Loop"
[1] The only interpretation that takes place is to recognize escape sequence '' as an embedded '.
