Bash loop through files and FTP them

David Carr

Bash Tutorials

    I have a folder of csv files that need uploading to a server I don’t want to do it manually, Bash can handle this task perfectly.

    This script will connect to an FTP server then loop through the csv files or any type specified and upload them. You cannot do a loop whilst inside of heredoc block like most examples do, instead the commands are written to a txt file.

    First set of variables are the ftp connection details and the type of file to look for, only needed when looking for certain types of files in this case .csv files.

    Each command ends in » ftp.txt this write to the file called ftp.txt if the file does not exist it’s created.

    Once connected do a cd (change directory) do go to the specified directory.

    To loop through the files a ‘for filename in‘ is used pass in the type variable the * is a wildcard to select all matching.

    to execute the code stored inside the txt file use ftp < ftp.txt use the -in flag to stop the prompt for a password.

    Lastly delete the ftp.txt file.

    echo open $HOST >> ftp.txt
    echo ascii >> ftp.txt
    echo user $USER $PASSWD >> ftp.txt
    echo cd /public_html/temp/ >> ftp.txt
    for filename in *$TYPE; do
        echo "put $filename"
    done >> ftp.txt
    echo bye >> ftp.txt
    ftp -in < ftp.txt
    rm ftp.txt

    Save this script as to run this:
