Check if File Exists

See more SFTP Examples

Demonstrates how to check to see if a file exists. Chilkat2-Python

import sys
import chilkat2

success = False

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

sftp = chilkat2.SFtp()

# Connect to the SSH server.  
hostname = "sftp.example.com"
port = 22
success = sftp.Connect(hostname,port)
if (success != True):
    print(sftp.LastErrorText)
    sys.exit()

# Authenticate with the SSH server.  Chilkat SFTP supports
# both password-based authenication as well as public-key
# authentication.  This example uses password authenication.
success = sftp.AuthenticatePw("myLogin","myPassword")
if (success != True):
    print(sftp.LastErrorText)
    sys.exit()

# After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp()
if (success != True):
    print(sftp.LastErrorText)
    sys.exit()

# Check to see if a file exists

# The return value is one of the following values:
# -1: Unable to check. Examine the LastErrorText to determine the reason for failure.
# 0: File does not exist.
# 1: The regular file exists.
# 2: It exists, but it is a directory.
# 3: It exists, but it is a symlink (only possible if followLinks is false)
# 4: It exists, but it is a special filesystem entry type.
# 5: It exists, but it is an unkown filesystem entry type.
# 6: It exists, but it is an socket filesystem entry type.
# 7: It exists, but it is an char device entry type.
# 8: It exists, but it is an block device entry type.
# 9: It exists, but it is an FIFO entry type.
