I am trying to old delete files from an FTP using Ruby net/sftp
, but I keep getting an error saying the file does not exist.
:error=>"Net::SFTP::StatusException (2, \"no such file\")"
I can manually delete files when logging in using the same creds, so I know I have permission.
require 'net/sftp'
ftp = Net::SFTP.start(@ftp_url, @ftp_user, :password => @ftp_pwd)
ftp.dir.entries('somePath').each do |entry|
begin
age_days = (Time.now.to_i - entry.attributes.atime) / 86400
if(age_days > ftp_max_file_age_days)
ftp.remove!(entry.name)
end
rescue Exception => e
# log error here
end
end
I prefer remove!
so everything happens synchronously in this case, but I have also tried remove
.
I also tried giving it the full path of the file instead of just the entry name (like 'somePath' + entry.name
instead of just entry.name
). I was thinking perhaps it was because I needed to change the working directory, which apparently net/sftp
does not allow.
Thanks in advance!
Check if entry
is a directory if yes then use ftp.rmdir
. like below -
require 'net/sftp'
ftp = Net::SFTP.start(@ftp_url, @ftp_user, :password => @ftp_pwd)
ftp.dir.entries('somePath').each do |entry|
begin
age_days = (Time.now.to_i - entry.attributes.atime) / 86400
if(age_days > ftp_max_file_age_days)
if File.directory?(entry.name)
ftp.rmdir(entry.name)
else
ftp.remove!(entry.name)
end
end
rescue Exception => e
# log error here
end
end
We were eventually able to delete files using the remove
method (instead of remove!
.) We made a small change to the way we provide the password.
We confirmed that permissions on the FTP did not change, so I think using non_interactive: true
may have been the trick.
require 'net/sftp'
def self.delete_report(endpoint, username, password, report_filename)
SSH_OPTIONS = { non_interactive: true }.freeze
report_filename_base = File.basename(report_filename, '.*')
Net::SFTP.start(endpoint, username, SSH_OPTIONS.merge(password: password)) do |sftp|
sftp.remove(report_filename)
sftp.remove("#{report_filename_base}.fin")
sftp.remove("processed/#{report_filename}")
sftp.remove("processed/#{report_filename_base}.fin")
sftp.remove("failed/#{report_filename}")
sftp.remove("failed/#{report_filename_base}.fin")
sftp.remove("failed/#{report_filename_base}.info")
end
I still don't fully understand why the same method did not work before, but we're able to delete files in subfolders too, as shown in this example.
