Linux - FTP Using Bash

Example of simple bash script ftp client

This script first defines variables such as hostname of the ftp server, username and password and then it creates an ftp session and uploads the specified file into your selected directory:

#!/bin/bash

ftp_site=127.0.0.1
username=ftpuser
passwd=pass

PS3='Select a destination directory: '

# bash select
select path in "." "/test" "public_html/myblog/" "backup/images/"
do
ftp -n $ftp_site<<EOF
quote USER $username
quote PASS $passwd
binary
cd $path
put $1
quit
EOF
break
done

Be sure to edit the ftp_site, username, and passwd variables above. You should also change the paths to whichever directories you most commonly upload your files to.

Executing the script:

$ chmod +x ftp_bash_script.sh
$ ./ftp_bash_script.sh file1

Example script output:

$ ./ftp_bash_script.sh somerandomfile
