![]() To compare the file creation date with the specific date, use the file creationTime attribute and PowerShell operator gt (greater than) to compare against the other specific date. $cutoffDate variable stores the specific date. In the above PowerShell script, the Get-ChildItem cmdlet gets the file item from the path specified and stores it in the $file1 variable. In PowerShell to compare the creation date with a specific date, use the PowerShell operator lt or gt. The file has attribute creationTime that specifies when the file was created. PS C:\Windows> $file1.LastWriteTime -gt $file2.LastWriteTime FalseĬool Tip: How to get file attributes using the Get-ChildItem in PowerShell! Compare File Creation Date in PowerShell PS C:\Windows> $file1.LastWriteTime -lt $file2.LastAccessTime True This could mean that the questioner wants to copy only files with these extensions but I think it means the questioner would like a batch script solution. PS C:\Windows>$file2 = Get-ChildItem -Path D:\Ps\powershell-compare-dates.png The questioner also states 'file extension is. The output of the above script to compare files based on the modified date are: PS C:\Windows>$file1 = Get-ChildItem -Path D:\Ps\powershell-command-alias.png Renaming the file doesnt change this time stamp. PowerShell operator on comparison of two files last modified date returns a boolean value. Date Modified: The date and time the file was last written (i.e, when its contents were last modified). In the above PowerShell script, the Get-ChildItem cmdlet uses the Path parameter to specify the file path and get the item.Ĭomparing two files modified date in PowerShell requires the file attribute LastWriteTime of each file to compare against the other file using the PowerShell operator lt or gt. $file1.LastWriteTime -gt $file2.LastWriteTime # Compare the two files with their lastwritetime $file2 = Get-ChildItem -Path D:\Ps\powershell-compare-dates.png $file1 = Get-ChildItem -Path D:\Ps\powershell-command-alias.png To compare the two files modified dates, use the below PowerShell script that uses Get-ChildItem to get the file item. ![]() The file has the attribute `LastWriteTime` which contains the modified date or last write time when a file was modified. maxdepth 1 -mtime -1 Note that to find files modified before 24 hours ago, you have to use -mtime +1 instead of -mtime -1. For example, to find all files in the current directory that have been modified since yesterday (24 hours ago) use: find. tsconfig.json 5.4 Recommended Content PowerShell Compare File Dates You can use the find command to find all files that have been modified after a certain number of days. Let’s look at how we can use the exec option to execute the stat commands for each file found by the find command: $ find. goto :EOF :NewestFileTime echo Last modification time of newest file is: NewestFileTime. But, using the exec option might be slower than xargs, and it’s more difficult to read. This is very easy to achieve: echo off for /F 'delims' I in ('dir /A-D /B /O-D 2>nul') do set 'NewestFileTimetI' & goto NewestFileTime echo There is no file in current directory. The exec option of the find command can be used similarly to the xargs command used above. The man page of the find command contains the full list of possible values for k. If you set a date prior to, Windows Explorer will not display this date, due to a limitation originally created for old FAT systems. %Tk – file’s last modification time in a format specified by k. ![]() The full list of escapes and directives can be found in the man pages, but let’s take a look at some of them: The hyphen (-) between the % sign and the width specifies that the interpreted value should be left-padded. The field width of a directive is specified after the % sign of a directive. 1 Answer Sorted by: 3 How about PowerShell This will find all files modified in the last two hours. If the width of the interpreted value for that directive is less than the specified width, then it is padded with whitespace. The unit for the width of a directive is the number of characters. In the above example, we’re specifying something called a field width inside the filename printf directive. If you don't care for a clean output, a 'quick and dirty. If you want to use it in a batchfile, double each to a, ta, and fa accordingly. (obviously, adapt the date-format in the findstr command to your system) Note: this is directly on command line. ![]()
