I have data in a file like below.
text1|text2
text3|text4|
I'm looking for a Power Shell command to count number of pipes present in thisfile.
Normally I would want you to show some effort but this is trivial enough I won't bother:
$pipeCount = (get-content file.txt -Raw).Split('|').count - 1
$pipeCount

Get only filename from full path of a file

I'm writing a PowerShell script to output the process,
$Process=chknull $_.Properties[0].Value
$Process_new=$Process -replace '(?<! .*) ','_'
The above code outputs the result as entire path of process, Eg:
C:\Windows\System32\Notepad.exe.
Is there a way, where I can get just "Notepad.exe"
If you're getting a full path return like that as a string you can set the value into a variable and then use split on it and grab the last entry in the resulting array.
Example:
("C:\Windows\System32\Notepad.exe." -split "\\")[-1]
Remember to use two "\" as it is also an escape character in regex.
([IO.FileInfo]"C:\Windows\System32\Notepad.exe").Name

my #hex_locations = ("$FindBin::Bin/../../../project/platform-aa-full/bb",
"$FindBin::Bin/../../../project/platform-aa-base/bb");
how do I use wild card to match any directory with project/platform-aa-* in above code?
Use glob
my #hex_locations = glob("$FindBin::Bin/../../../project/platform-aa-*/bb");
