Rename command not working when using JSch – CentOS

Trying to rename a file/folder using JSch API executing them as shell commands is not working. mkdir and rmdir are working fine.

JDK version – 11.
JSch version – 0.1.55.

Using the following code.

ChannelExec execChannel = null;
try {
  execChannel = (ChannelExec) session.openChannel("exec");
  execChannel.connect();
  execChannel.setCommand("rename dir1 dir2");
  execChannel.start();
} catch (JSchException ex) {
  throw new IOException(ex);
} finally {
  if (execChannel != null) {
    execChannel.disconnect();
  }
}

Update:

  • The SFTP server is hosted on a CentOS machine
  • mv, ren, rename – None of them worked
  • How do we know the command did not work – The folder name is still the old name. Also the execChannel.getExitStatus() gives -1. No error is thrown

    If you are using Jsch I believe that the remote host is a Unix-like system. There is no command rename in Unix. Use mv instead.

    You are most probably executing a wrong command. If you are connecting to Linux, the command to use is mv.

    Though, you should not use shell commands for trivial file operations like creating and removing a directory and renaming a file/directory. That’s a very fragile approach.

    Instead, use the the standard file management API of SSH, the SFTP (ChannelSftp in JSch). 

    ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
sftpChannel.connect();

sftpChannel.mkdir("/path/dir1")
sftpChannel.rename("/path/dir1", "/path/dir2");
sftpChannel.rmdir("/path/dir2");
