This is my first post :D ... I have never needed to post since all my answers have always been already answered. I look but didn't find anything to answer this.
I have a directory ( call it temp ) in C:\ and I need to find all files in it (recursively) that contain ANY of these characters ~!##$%^&*()+., OR a space.
I then need them listed with their location, I dont care about the date or permissions (infact I would prefer them removed)
I also need the option to filter *.htm
I tried playing with GCI and Select-String, but select-string kept reading the content of my files and I am not very good with regular expressions.
Thanks in advance for the help, I know the people on here know their stuff (4 years before I had to post a question :D)
Try this:
$files = Get-ChildItem "c:\PST\"
$files = ($files | Where-Object {$_.BaseName.IndexOfAny("~!##$%^&*()+., ".ToCharArray()) -ne -1})
$files

not sure about how to correctly title this, please change it if you prefer
given that my code actually works, I'd like to have a peer review to increase the quality of it.
I have a folder full of .zip files. Theese files are streams of data (identifiable by their stream name) daily offloaded. There could be more than one daily file per stream, so I need to grab the last one in order of time. I can't rely on posix timestamp for this, so files expose timestamp on their name.
Filename example:
XX_XXYYZZ_XYZ_05_AB00C901_T001_20170808210052_20170808210631.zip
Last two fields are timestamps, and I'm interested in the second-last.
other fields are useless (now)
I've previously stored the stream name (in this case XYZ_05_AB00C901_T001 in the variable $stream
I have this line of code:
match=$(ls "$streamPath"/*.zip|grep "$stream"|rev|cut -d'_' -f2|rev|sort|tail -1)
And what it does is to search the given path for files matching the stream, cutting out the timestamp and sorting them. So now that I know what is the last timestamp for this stream, I can ls again, this time grepping for $streamand $match togegher, and I'm done:
streamFile=$(ls "$streamPath"/.zip|grep "$stream.*$match\|$match.*$stream")
Question time:
Is there a better way to achieve my goal ? Probably more than one, I'll prefer one-liner solution, tough.
ShellChecks advices me that it would be better to use a for loop or a while cycle instead of ls, to be able to handle particular filenames (which I'm not facing ATM, but who knows), but I'm not so sure about it (seems more complicated to me).
Thanks.
O.
Thanks to the page suggested by Cyrus I chose to go with this solution:
echo "$file"|grep "$stream"|rev|cut -d'_' -f2|rev|sort|tail -1
done < <(find "$streamPath" -maxdepth 1 -type f -name '*.zip' -print0)
Problem:
Update a specific string within numerous configuration files that are found within the subfolders of a partial path using PowerShell.
Expanded Details:
I have multiple configuration files that need a specific string to be updated; however, I do not know the name of these files and must begin my search from a partial path. I must scan each file for the specific string. Then I must replace the old string with the new string, but I must make sure it saves the file with its original name and in the same location it was found. I must also be able to display the results of the script (number of files affected and their names/path). Lastly, this must all be done in PowerShell.
So far I have come up with the following on my own:
$old = "string1"
$new = "string2"
$configs = Get-ChildItem -Path C:\*\foldername\*.config -Recurse
$configs | %{(Get-Content $_) -Replace $old, $new | Set-Content $_FullName
When I run this, something seems to happen.
If the files are open, they will tell me that they were modified by another program.
However, nothing seems to have changed.
I have attempted various modifications of the below code as well. To my dismay, it only seems to be opening and saving each file rather than actually making the change I want to happen.
$configFiles = GCI -Path C:\*\Somefolder\*.config -Recurse
foreach ($config in $configFiles) {
(GC $config.PSPath) | ForEach-Object {
$_ -Replace "oldString", "newString"
} | Set-Content $config.PSPath)
}
To further exasperate the issue, all of my attempts to perform a simple search against the specified string seems to be posing me issues as well.
Discussing with several others, and based on what have learned via SO... the following code SHOULD return results:
GCI -Path C:\*\Somefolder\*.config -Recurse |
Select-String -Pattern "string" |
Select Name
However, nothing seems to happen. I do not know if I am missing something or if the code itself is wrong...
Some questions I have researched and tried that are similar can be found at the below links:
UPDATE:
It is possible that I am being thwarted by special characters such as
+ and /. For example, my string might be: "s+r/ng"
I have applied the escape character that PowerShell says to use, but it seems this is not helping either.

I will continue my research and continue making modifications. I'll be sure to notate anything that get's me to my goal or even a step closer. Thank you all in advance.
My google-fu has failed me, so I'd love to get some help with this issue. I have a directory full of markup files (extension .xft). I need to modify these files by adding string literals and the filename (without the file extension) to each file.
For example, I currently have:
<headerTag>
<otherTag>Some text here </otherTag>
<finalTag> More text </finalTag>
What I need to end up with is:
<modifiedHeaderTag>
<secondTag> filenameGoesHere </secondTag>
<otherTag>Some text here </otherTag>
<finalTag> More text </finalTag>
So in this example,
"<modifiedHeaderTag>
<secondTag>"
would be my first string literal (this is a constant that gets inserted into each file in the same place),
filenameGoesHere
would be the variable string (the name of each file) and,
"</secondTag>"
would be my second constant string literal.
I was able to successfully replace text using:
(Get-Content *.xft).Replace("<headerTag>", "<modifiedHeaderTag>")
However, when I tried
(Get-Content *.xft).Replace("<headerTag>", "<modifiedHeaderTag> `n
<secondTag> $($_.Name) </secondTag>")
I just got an error message. Replacing $($_.Name) with ${$_.Name) also had no effect.
I've tried other things, but this method was the closest that I had gotten to success. I would appreciate any help that I can get. It's probably simple and I'm just not seeing something due to inexperience with Powershell, so a helping hand would be great.
If the above isn't clear enough, I'd be happy to provide more info, just let me know. Thanks everyone!
Here's my approach, assuming you have all of the XFT's in one folder and you want to write the updates back to the same file:
$path = "C:\XFTs_to_Modify"
$xfts = Get-ChildItem $path -Include "*.xft"
foreach ($xft in $xfts) {
$replace = "<modifiedHeaderTag>
<secondTag> $($xft.Name) </secondTag>"
(Get-Content *.xft).Replace("<headerTag>", $replace) | Set-Content $xft.FullName -Force
}
Please help. Trying to figure out how to replace a string in PowerShell, but don't know the rest of the string. I have this:
(Get-Content $file) -replace[regex]::Escape('file='*''),('file='+$_.BaseName) | Set-Content $file
I don't know what comes after file=
I tried my code, but it replaces it multiple times instead of just once.
So trying to replace file=* with filename=$_.BaseName.
Thanks for looking.
Just an FYI for anyone using the latest version of PowerShell Community Extensions (http://pscx.codeplex.com), there is a new command called Edit-File that handles this sort of thing nicely (works hard to preserve the file's original encoding):
Get-Item test.txt | Foreach {$bn=$_.BaseName; $_} |
Edit-File -Pattern '(file=).*' -Replace "`${1}$bn"
In theory I shouldn't need the Foreach stage but it seems I've found a limitation in how -PipelineVariable does not work with parameters that aren't pipeline bound. Hmm, add that to the Pscx backlog.
Frequently I want to do something like:
$foo=ls foo.txt|select FullName
$bar=$foo.split("\\"); # or replace or some such
But if I now look at the strings in bar they look like this:
#{FullName=C:\path\to\foo.txt}
Since I know how long the decorations are I can manually get the substring. But that seems hacky - is there a way to just get the path part as a string?
Edit: to illustrate another similar issue, based on some questions, if I do:
$foo -replace("\\","/")
I get:
#{FullName=C:/src/tss/THSS-Deployment-Config/foo.txt}
I am doing lots of manipulations of these file names for a migration between different CM repositories. I was thinking 'if I could just get the whole path as a string'...
This is my first serious outing into PS. So maybe my mindset is just wrong.
A few quick ways, all using the Split-Path cmdlet which is perfect for this:
$foo= ls foo.txt | select FullName
$bar = Split-Path $foo.fullname
Or:
$foo= ls foo.txt | select -ExpandProperty FullName
$bar = Split-Path $foo
Or even shorter:
$bar = Split-Path (gci foo.txt).fullname
#arco444 gave me the missing piece. To get the full path with the filename as a string, the easiest thing I could come up with was:
$bar=(Split-Path $foo.FullName) +"\"+ (Split-Path $foo -leaf)
I'm not sure if there's an easier way to combine get the whole path as a string.
