Shell – House keeping removing 30+ days old files using shell script

scriptshellunix

So I have to bit of housekeeping for old backups and have the following code working on sh:

find /home/backups -mtime +30 -type f -exec rm -rf {} \;

This works fine as know the location/path, so if the path is diff on another machine how can I modify the command to work on all machines?

If I use the command below that will delete all files 30 days old but I'm only looking to clean up these unique set of backup files only:

find . -mtime +3 -exec rm {} ';'

Thanks

I don't know how would you execute the command on all machines, automatically via ssh? or manually?

anyway, if you want to save the effort of typing path, you may consider that on each machine create a variable with same name, e.g. BACKUP_DIR, it saves the path you need to do the cleaning job.

Then, in your find command, don't hardcode any path, but use the variable.

if you do it automatically via ssh, you know the path when you establish the connection. then just add the path in your find.

You could try adding in a /Q /S, though be aware that this may not in fact do what you really want it to:

/Q Quiet mode, do not ask if ok to delete on global wildcard
/S Delete specified files from all subdirectories

E:\forfiles -p "H:\SHARED\Scans" -s -m . -d -7 -c "cmd /c del /Q /S @path"

You are probably better off either using CSCRIPT (with your choice of VBScript or JScript) or PowerShell. Check out this answer from StackOverflow: https://stackoverflow.com/questions/1575493/how-to-delete-empty-subfolders-with-powershell

Here is some vbscript to accomplish a similar task:

Dim fso, folder, folders
Set fso = CreateObject("Scripting.FileSystemObject")
Set parent = fso.GetFolder("H:\SHARED\Scans")
Set folders = parent.SubFolders

' delete any folder older than 7 days
For Each folder in folders
    If Abs(DateDiff("d",Date, folder.DateCreated)) > 7 Then
        folder.Delete(True) 'force delete
    End If
Next
