Sending file to server via FTP via linux command line

Question

Good morning. I have some doubts regarding a project I’m finishing using linux ( I don’t have much domain ).

I have a program written in C that generates files. txt, I must make this program run every day ( until then, I know I must use crontab ). After this file is generated I must send it to a server via FTP. At this point do not know how to proceed, given that I must access the directory that the file was generated, open connection with FTP and upload it.

Another question I’m having is, what is the advantage of using an upload to a server through the FTP protocol?

Edit 1:

I performed the script and until then it works when I step in the file variable the file-source and source-file, however it is necessary to declare a new name, and I would just like to duplicate the files from one place to another.

Follows script:

#!/bin/bash
HOST='192.168.8.151'
usuario='ftp_tentativas'
senha='passwdwillian01'
arquivo='/var/www/html/log/Export/*.csv'

ftp -n $HOST <<END_SCRIPT
user ${usuario} ${senha}

cd recebe
put $arquivo
cp /var/www/html/log/Export/*.* /var/www/html/log/Enviados/.
rm /var/www/html/log/Export/*.* 

quit
END_SCRIPT
exit 0

Error showing:

?Invalid command
Could not create file.
Remove directory operation failed.

When done 'by hand' directly by the console it shows the destination equal to the source, not creating the file correctly.

ftp> put /var/www/html/log/Export/*.csv
local: /var/www/html/log/Export/Relatorio_Qualidade_20180730.csv remote: /var/www/html/log/Export/Relatorio_Qualidade_20180730.csv

Answer 1

first check if you have the FTP client installed on the machine that will run cron: apt-get install ftp -y
# if the distribution is based on debian

you can create scrip will run by cron:

#!/bin/bash
HOST='192.168.8.151'
usuario='ftp_tentativas'
senha='passwdwillian01'

arquivo='*.csv'

cd /var/www/html/log/Export/

ftp -n $HOST <<END_SCRIPT
user ${usuario} ${senha}
prompt
mput $arquivo
quit
END_SCRIPT
cp /var/www/html/log/Export/*.* /var/www/html/log/Enviados/.
rm /var/www/html/log/Export/*.* 
exit 0

Generally FTP protocol is not widely used because it has no encryption, it is usually used SFTP, FTPS.
