[quote="will.waterston@gmail.com"]I'm using [m]Session.FileExists(mypath)[/m] to test if a directory exists, but without success.

Is this method meant for testing path existence or only files?

I've tried [m]FileExists("/myroot/mypath/")[/m] both with and without the trailing [m]/[/m] and both are returning false even though the directory does exist. If this method is only meant for files then how do I test directory existence?

I found some more notes in the forum on this and [m]FileExists()[/m] is supposed to support directories as well as files. Below is log for the events surrounding the failure. The script failure explains why the method is returning false, but what can I do stop the script failing on the unexpected directory listing?

Looking further this appears to be related to an unexpected directory listing format. I have seen several comments suggesting to change the [m]ls[/m] command using [m]sed[/m] to modify the format, but I cannot see where this is done using .NET assembly, can someone point me in the direction of the doco for this?

Thanks

Testing for remote directory existence before copying files

2023-02-01 04:59

I'm using Session.FileExists(mypath) to test if a directory exists, but without success.

Is this method meant for testing path existence or only files?

I've tried FileExists("/myroot/mypath/") both with and without the trailing / and both are returning false even though the directory does exist. If this method is only meant for files then how do I test directory existence?

I found some more notes in the forum on this and FileExists() is supposed to support directories as well as files. Below is log for the events surrounding the failure. The script failure explains why the method is returning false, but what can I do stop the script failing on the unexpected directory listing?

Looking further this appears to be related to an unexpected directory listing format. I have seen several comments suggesting to change the ls command using sed to modify the format, but I cannot see where this is done using .NET assembly, can someone point me in the direction of the doco for this?
