$match = Select-String -LiteralPath path\to\ngrok_log.txt -Pattern $pattern This line also seem to be not needed: $List_IP = Get-ChildItem -Path "C:\ngrok_log.txt"Īnd | Select-Object -ExpandProperty Line should definitely be removed.Īs for the regex pattern, what you have currently might work fine but if you want more precision you can give this one a try: (?<=url=tcp://)?\.tcp\.(?:ap|au|eu|in|jp|sa|us)\.ngrok\.io:\b' So those 2 lines should be changed to: Write-Host "SUCCESS - $pattern `n$($)" Ī simple example: $match = 'foo bar baz' | Select-String bar You could use grep:-E w+ searches for words-o only prints the portion of the line that matches cat temp Some examples use 'The quick brown fox jumped over the lazy dog,' rather than 'Lorem ipsum dolor sit amet, consectetur adipiscing elit' for example text. Line property when what you're actually looking for is the matched value of your pattern, the same would be happening in $sel | Out-File.
WINDOWS GREP TO EXTRACT TEXT FROM A FILE CODE
Your code looks good, the main issue is when you do ".$sel" you're coercing a MatchInfo instance to be a string and when coerced the result is its. So., how can I extract the IP address from that file and save it to a new one? I don't really understand the "pattern" part of this script, everytime I restart the ngrok I get new random IP address like this: It works, but it's saving the whole line that contains the IP address instead just the IP address: t=T16:17:15+0300 lvl=info msg="started tunnel" obj=tunnels name=command_line addr=//localhost:8865 url=tcp://4.tcp.eu.ngrok.io:10355 Write-host "ERROR - $IP does not contain $pattern" $sel = select-string -list $IP -pattern $pattern | Select-Object -ExpandProperty Line Recently I created this powershell script: $List_IP = Get-ChildItem -Path "C:\ngrok_log.txt" The address that I want to extract is 4.tcp.eu.ngrok.io:10355 T=T16:17:16+0300 lvl=info msg="update available" obj=updater T=T16:17:15+0300 lvl=info msg="client session established" obj=csess T=T16:17:15+0300 lvl=info msg="tunnel session started" obj=ssion T=T16:17:15+0300 lvl=info msg="using configuration at default config path" path=C:\\Users\\***\\AppData\\Local/ngrok/ngrok.yml
That's how the file looks like: t=T16:17:15+0300 lvl=info msg="no configuration paths supplied" The text file that contains the IP address it's an output file from an application called ngrok.
You might want to redirect the results from grep into a new file and examine this with vi / less.I have a text file and it's contains an IP address what I want to extract and save it to a new text file. Please mark the words of caution at the end of the second paragraph.
WINDOWS GREP TO EXTRACT TEXT FROM A FILE DRIVER
Terminal and if the terminal driver interprets some of it as commands. binary-files=text might output binary garbage, which can have nasty side effects if the output is a Processes a binary file as if it were text this is equivalent to the -a option. That a binary file does not match this is equivalent to the -I option. That a binary file matches, or no message if there is no match. By default, TYPE is binary, and grep normally outputs either a one-line message saying If the first few bytes of a file indicate that the file contains binary data, assume that the file is Process a binary file as if it were text this is equivalent to the -binary-files=text option. You can use grep anyway to search through the file - it does not really care if the input file is really text or not.
