java - Using JSch, is there a way to tell if a remote file exists without doing an ls?

Question

Using JSch, is there a way to tell if a remote file exists without doing an ls and looping through the files to find a name match?

Thanks

Answer 1

This is how I check directory existence in JSch.

Note: not related to this question, but some may find it useful.

Create directory if dir does not exist

ChannelSftp channelSftp = (ChannelSftp)channel;
String currentDirectory=channelSftp.pwd();
String dir="abc";
SftpATTRS attrs=null;
try {
    attrs = channelSftp.stat(currentDirectory+"/"+dir);
} catch (Exception e) {
    System.out.println(currentDirectory+"/"+dir+" not found");
}

if (attrs != null) {
    System.out.println("Directory exists IsDir="+attrs.isDir());
} else {
    System.out.println("Creating dir "+dir);
    channelSftp.mkdir(dir);
}
