SFTP Get/Set File Permission

See more SFTP Examples

Demonstrates how to set the permissions of a file on the SFTP server. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let sftp = chilkat::SFtp::new();

// Connect to the SSH/SFTP server.  
let hostname = "sftp.example.com".to_string();
let port = 22;
if sftp.connect(&hostname, port).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
if sftp.authenticate_pw("myLogin", "myPassword").is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// After authenticating, the SFTP subsystem must be initialized:
if sftp.initialize_sftp().is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Get the file permissions for the "hamlet.xml" file on the server.
// The hamlet.xml file is located in the qa_data directory found under the HOME directory of the SSH user account.
// We are passing the remote file path (we are not passing a file handle returned by a previous call to OpenFile).
let is_handle = false;
let follow_links = true;
let perm_val = sftp.get_file_permissions("qa_data/hamlet.xml", follow_links, is_handle);
if perm_val < 0 {
    println!("{}", sftp.last_error_text());
    return;
}

// Note: Filesystem permissions on Linux/Unix/MacOSX are typically written in octal (POSIX file permissions).  For example 0644 is octal.
// To convert to decimal: octal 644 = 6*8^2 + 4*8 + 4 = 420 (decimal)
// 
// The server may return a permissions value (in octal) such as 100644.
// The "100" indicates the file type, such as regular file or directory. 

// Show the decimal value of the permissions
println!("decimal permissions value: {}", perm_val);

// To set the file permissions, pass the integer value.
// Let's change the permissions to 0664, which is 6*8^2 + 6*8 + 4 = 436 (decimal)
if sftp.set_permissions("qa_data/hamlet.xml", is_handle, 436).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

println!("Success.");
