Uploading files to FTP/SFTP using CURL

Hello,

Today I am writing below article which can help you to upload files to SFTP/FTP by using CURL.

Ok why we need that ? Let me tell explain!!

How we login into SFTP/FTP ?



[root@virt03 test]# sftp 192.168.56.110 Connecting to 192.168.56.110... root@192.168.56.110's password: sftp> ls anaconda-ks.cfg       nodes                 post-install          post-install.log
sftp> exit

and uploading files with put command. Its a lengthy way. So recently I have gone through few articles and with some R&D I have modified it as script and command-line argument support.So you can call the script with filename as argument. 

So Lets do this!!!

  1. Command 1 : This is for uploading a single to SFTP/FTP by using CURL. 
SFTP
curl -k  -u virt03:virt03 -T file4  sftp://192.168.56.110/home/virt03/

Syntax : 

curl -k  -u username:password -T filename sftp://IP_Addreess OR Hostname:/path/to/upload 

FTP

curl -k  -u virt03:virt03 -T file6  ftp://192.168.56.110

Example

[root@virt03 test]# curl -k  -u virt03:virt03 -T file4  sftp://192.168.56.110/home/virt03/
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
[root@virt03 test]# touch file6
[root@virt03 test]# curl -k  -u virt03:virt03 -T file6  ftp://192.168.56.110
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0

[root@virt03 test]# ls /home/virt03/ | grep file
file1
file2
file3
file4
file5
file6
[root@virt03 test]#



So hope you understand whats happening now. Lets make some script!!! 

[root@virt03 test]# ls
file1  file3  file5  file7  file9  lab2.sh     upload1.sh
file2  file4  file6  file8  lab1   rackspace3  upload2.sh
[root@virt03 test]# ls /home/virt03/ | grep file
file1
file2
file3
file4
file5
file6
[root@virt03 test]# ./upload1.sh file7
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
[root@virt03 test]# ls /home/virt03/ | grep file
file1
file2
file3
file4
file5
file6
file7
[root@virt03 test]# ./upload2.sh file8 file9
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
[root@virt03 test]# ls /home/virt03/ | grep file
file1
file2
file3
file4
file5
file6
file7
file8
file9
[root@virt03 test]# 

And the scripts are 

[root@virt03 test]# tail upload*
==> upload1.sh <==
#!/bin/bash

curl -k  -u virt03:virt03 -T "{$1}" sftp://192.168.56.110/home/virt03/

==> upload2.sh <==
#!/bin/bash
curl -k  -u virt03:virt03 -T "{$1,$2}" sftp://192.168.56.110/home/virt03/
[root@virt03 test]#


I hope you can understand what the scripts are doing. To upload more than 2 files you can use for loop like below.


for i in file1 file2 file3 file4 file5
do
./upload1.sh $i
done

Example: 


[root@virt03 test]# for i in file10 file11 file12
> do
> ./upload1.sh $i
> done
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:--  0:00:01 --:--:--     0
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0

[root@virt03 test]# ls /home/virt03/ | grep file1
file1
file10
file11
file12
[root@virt03 test]#


Hope you understand!! , If any doubts please dont hesitate to ask.
