Powershell to read some strings from each line - powershell

Question

I have a requirement like:
Have a text file containing the following in the following pattern
172.26.xxy.zxy:Administrator:Password
172.26.xxy.yyx:Administrator:Password
172.26.xxy.yyy:Administrator:Password
172.26.xxy.yxy:Administrator:Password
I need my powershell script to read each word and use that word whereever required. For example,
foreach(something)
{
I want the IP's(172.26.---.---) to read and store the value as a variable.
I want to store the two words after **:** in seperate variables.
}
How can this be done? I know to read an entire file or get some specific string. But I need the same to be done on each line.Any help would be really appreciated.

Answer 1

Something like this? You can just split on the : and then store your variables based on the index
$contents = Get-Content C:\your\file.txt
foreach($line in $contents) {
$s = $line -split ':'
$ip = $s[0]
$user = $s[1]
$pass = $s[2]
write-host $ip $user $pass
}
minor edit: "t" missing in content.

Answer 2

You can write a regular expression to replace to remove the parts you do not need
$ip_address= '172.26.xxy.zxy:Administrator:Password' -replace '^(.+):(.+):(.+)$','$1'
$user= '172.26.xxy.zxy:Administrator:Password' -replace '^(.+):(.+):(.+)$','$2'
$pwd= '172.26.xxy.zxy:Administrator:Password' -replace '^(.+):(.+):(.+)$','$3'

Answer 3

I think the more generic and pure Powershell way would be something like this:
Select-String "(.*):(.*):(.*)" c:\file.txt |
Select #{Name="IP"; Expression = {$_.Matches.Groups[1]}},
#{Name="User"; Expression = {$_.Matches.Groups[2]}},
#{Name="Password"; Expression = {$_.Matches.Groups[3]}}
The Output would be then an array of objects each having three properties IP, User and Password. So you can now use them for your purposes, or just add more commands at the end of the pipe.
