How to get the amount of hours passed since the last modification of each file?
I am using this batch script to give me output of the last modified date using the Date and time format:
forfiles /M "my file.txt" /C "cmd /c echo @file @fdate @ftime" > ".\Logs\my file.txt"
But instead of date and time, I want it to show me when it was updated by hours,开发者_C百科 minutes and seconds.
For example, the above code output looks like this:
"my file.txt" 6/12/2022 2:44:58 AM
my desired result is:
"my file.txt" was updated 1 hours 3 minutes 2 seconds ago
How can get this result and which language is more convenient for this?
A PowerShell solution:
The example uses:
Get-ChildItem
to list the files of interestNew-TimeSpan
to determine the time span that has elapsed since the file was last written to.-f
, the format operator, to synthesize the output string, in combination with an expandable (double-quoted) string ("..."
).-replace
, the regular-expression-based string replacement operator, to remove unused units from the friendly time-stamp description.
Get-ChildItem -LiteralPath . -Filter *.txt |
ForEach-Object {
$timeSpan = New-TimeSpan -Start $_.LastWriteTime
"`"$($_.Name)`" was last updated {0} day(s), {1} hour(s), {2} minute(s), {3} second(s) ago" -f
$timeSpan.Days, $timeSpan.Hours, $timeSpan.Minutes, $timeSpan.Seconds -replace
'\b0 day\(s\), (0 hour\(s\), (0 minute\(s\), )?)?'
}
As per my comment:
Get-ChildItem -Path 'D:\Temp\appsettings.txt' | Select-Object -Property '*'
# These are all the possible properties in Windows for a file.

Formatting dates is just this:
https://devblogs.microsoft.com/scripting/formatting-date-strings-with-powershell/
You can add any other string you want in that formatted output as well.
Get-ChildItem -Path 'D:\Temp\appsettings.txt' |
Select-Object -Property FullName, LastWriteTime
# Results
<#
FullName LastWriteTime
-------- -------------

Clear-Host
Get-ChildItem -Path 'D:\Temp\*.txt' |
Select-Object -Last 1 |
ForEach-Object {
$FileTime = New-TimeSpan -Start $PSItem.LastWriteTime
"$($PSItem.Name) was updated $($FileTime.Days) days $($FileTime.Hours) hours $($FileTime.Minutes) minutes $($FileTime.Seconds) Seconds ago"
}
# Results
