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

                                 Dload  Upload   Total   Spent    Left  Speed

[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.
