Vista - do something for each token in a line separated by comma

Hello,

a simple problem in NT-Shell, but in Powershell i find no solution (new
in PS)

I have a Textfile where in each line are members of a group. These members
are separated by a comma. I find no way to do something with each user.
I have tried something with get-content and foreach-object.
But everything interprets the wohle line as 1 string.
If i take a textfile with each user in one line, theres no problem to handle
with.

heres a exampel for the textfile:

mary,john,paul,henry
mary,john
mary,john,paul,henry,george,hanne,anne,tom

i want to read each line and in each line do something with each user
separated with comma. The number of users in each line varies.

Pls give me some hints.

Thx and Greets
Max

Hi MaxMed,

You can split method, on the comma char, on each line and then run foreach
on the result:

get-content yourfile.txt | foreach {
$users = $_.split(",")
$users | foreach { "do somthing" }
}

Hi Shay Levi :-)

Thanks a lot! It works!!
One more Problem: Is there a posibility to remove spaces in each token?

The string type has three methods to trim white space characters (or set
of characters) from a string, you can get them by running:

PS > " just a string " | gm tr*


TypeName: System.String

Name MemberType Definition
---- ---------- ----------
Trim Method System.String Trim(Params Char[] trimChars), System.String
Trim()
TrimEnd Method System.String TrimEnd(Params Char[] trimChars)
TrimStart Method System.String TrimStart(Params Char[] trimChars)



Trim - Removes all trailing occurrences of a set of characters specified
in an array from the current String object.
TrimEnd - Removes all trailing occurrences of a set of characters specified
in an array from the current String object.
TrimStart - Removes all leading occurrences of a set of characters specified
in an array from the current String object.


# remove leading and trailing spaces from a string
PS > " just a string ".trim()
just a string

Hello,

I have a very similar issue that is fairly straight forward with a batch file, but I would like to learn a simpler cleaner version with Powershell.

We have text files that look like this -

johndoe@abccompany.com,janedoe@abcco...abccompany.com,

etc.

all on one line of text. We want to just strip out the username (everything before the @ symbol) and nothing more then put them into a new text file 1 per line. (or to excel, since Powershell can do this)
The problem that I have been encountering is that when I try something like this -

$a = Get-Content ("\\network location\long_names.txt")
$b = $a.split('@')

I get a result that looks like this -

johndoe
abccompany.com,janedoe
abccompany.com,xyzuser
abccompany.com,somebody

etc.

Is there a way to only get the username and put it into new file with one username per line?

I am very new to PowerShell but am starting a 20 hour course, so hopefully I'll know more soon. Any help would be appreciated. We have already accomplished this with a batch file that we wrote up in 30 mins or so, but it would be nice to see these real world examples able to be accomplished with Powershell.

Thanks!

$s = "johndoe@xxxxxx,janedoe@xxxxxx,xyzuser@xxxxxx,somebody@xxxxxx,"
[regex]::matches($s,',?(?<name>[^@]+)@[^\.]+\.\w+') | foreach { $_.groups['name'].value
}

johndoe
janedoe
xyzuser
somebody



To process a file:

get-content <file> | foreach {
[regex]::matches($_, ',?(?<name>[^@]+)@[^\.]+\.\w+') | foreach { $_.groups['name'].value
}
}
