Windows PowerShell provides built-in capabilities that closely mimic tail -f
functionality:
Get-Content -Path "C:\logs\app.log" -Wait -Tail 10
For more advanced filtering while tailing:
Get-Content -Path "C:\logs\app.log" -Wait | Where-Object { $_ -match "ERROR" }
For developers preferring visual interfaces:
- BareTail: Free tool with highlighting and pause functionality
- LogExpert: Open-source multi-tab log viewer with regex search
- GSAR: Handles large log files efficiently with bookmarking
For custom solutions, here's a basic implementation:
using System;
using System.IO;
class LogTail {
static void Main(string[] args) {
using (var fs = new FileStream("app.log", FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
using (var sr = new StreamReader(fs)) {
fs.Seek(0, SeekOrigin.End);
while (true) {
string line = sr.ReadLine();
if (line != null) Console.WriteLine(line);
else System.Threading.Thread.Sleep(100);
}
}
}
}
Create a reusable function for your profile:
function Watch-Log {
param (
[string]$Path,
[int]$Lines = 10,
[string]$Filter = "*"
)
Get-Content -Path $Path -Wait -Tail $Lines |
Where-Object { $_ -like $Filter }
}
Standalone executables that don't require installation:
- log-watch.exe: Single binary with color output
- winTail: Supports multiple files simultaneously
- mtail: Go-based tool with metric extraction
For developers who can use WSL:
wsl tail -f /mnt/c/logs/app.log
This provides native tail
behavior while accessing Windows files.
As a developer who frequently switches between Linux and Windows environments, I've always missed the simplicity of tail -f
for monitoring log files in real-time. While Windows has its own set of tools, none provide the same seamless experience out of the box.
For basic log monitoring, these built-in Windows tools can help:
# PowerShell alternative (Windows 10+)
Get-Content -Path "C:\logs\app.log" -Wait -Tail 10
This PowerShell command mimics tail -f
behavior, showing the last 10 lines and updating in real-time. However, it lacks some advanced features like pausing the output.
For more robust solutions, these tools offer excellent functionality:
- BareTail (Free): Lightweight GUI tool with highlighting and search
- LogExpert (Free): Advanced log viewer with multiple file support
- GSAR (Free): Command-line tool similar to Unix utilities
If you prefer a custom approach, here's a simple Python script that replicates tail -f
with pause functionality:
import time
import os
def tail_f(file_path):
with open(file_path, 'r') as f:
# Go to end of file
f.seek(0, os.SEEK_END)
while True:
line = f.readline()
if not line:
time.sleep(0.1)
continue
yield line
if __name__ == '__main__':
for line in tail_f('application.log'):
print(line, end='')
For Windows power users, this enhanced PowerShell script adds pause functionality:
$logFile = "C:\logs\app.log"
$paused = $false
function Show-Help {
Write-Host "Commands:"
Write-Host " p - Pause output"
Write-Host " r - Resume output"
Write-Host " q - Quit"
}
Show-Help
Get-Content -Path $logFile -Wait -Tail 10 | ForEach-Object {
if (-not $paused) {
$_
}
if ([Console]::KeyAvailable) {
$key = [Console]::ReadKey($true)
switch ($key.Key) {
'P' { $paused = $true; Write-Host "n[PAUSED]" }
'R' { $paused = $false; Write-Host "n[RESUMED]" }
'Q' { exit }
}
}
}
The best option depends on your specific needs:
Tool | Type | Pause Support | Search |
---|---|---|---|
PowerShell | Built-in | With custom script | Basic |
BareTail | GUI | Yes | Advanced |
Python Script | Custom | Yes | None |
For most developers, I recommend starting with PowerShell for quick checks and BareTail for more intensive log analysis sessions.
