Powershell to edit multiple strings in text file

Hi,

I am looking for a powershell script to edit multiple lines in a text file where value of the string is with in quotes "value"

Save changes with value_filename

Is this something that can be done to change multiple strings/lines values in txt file using powershell

Thanks

Can you provide an example of what you're trying to do?

for example i have a file with below entry

deviceManagement[1]["securePort"] = "443"
deviceManagement[2]["ifName"] = "bdg2"
radiusAttributes[1]["nasIdentifier"] = "100"

to
deviceManagement[1]["securePort"] = "80"
deviceManagement[2]["ifName"] = "dgp2"
radiusAttributes[1]["nasIdentifier"] = "25"

There will be 50 + lines for which changes needs to be done either input or from text file

hope it is clear

create txt file with all changes need to be applies, for example:

securePort 80
nasIdentifier 25

the powershell script will look for all entries ["securePort"] and change value to "80"
same thing goes to nasIdentifier.

is that would be ok?

There is something missing in line 9, $value is never set, and I cannot see how you should do that.
Another, similar way:

$map = import-csv C:\Temp\Values.txt -delimiter '  ' -header key, value

get-content c:\temp\source.txt | foreach-object {
   $line = $_
   foreach ($cur in $map)
   {  $line = $line -replace "(.+\[""$($cur.key)""\] =).*", "`$1 $($cur.value)"   }
  $line
} | out-File C:\Temp\Output.txt

Open in new window

Line 9 should be:
$value = $map[$_]
