ftp-scriptingIn this post, I will show you some Unix shell scripts to automatically work with FTP servers. These are scripts that FTP to a remote server and then close the FTP connection to that server when the file has been transferred.These are the shellcodes for those three script files.CODE: Execute_FTP.sh
./Parser.sh 10.132.207.2 username password /home/cybrary/Documents/OUT DiskAlert.txt /tmp/Alert/VDS
CODE: Parser.sh
set -xif [ $# != 6 ]; thenecho "Usage./Parser.sh IP USERNAME PASSWORD SOURCE FILENAME DESTINATIONwhereIP ------------- IP address of remote serverUSERNAME-------- username with which to establish ftp sessionPASSWORD-------- password for the above mentioned USERNAMESOURCE --------- source directoryFILENAME ------- name of the file to be ftpedDESTINATION----- path at remote directory at which file is to be kept"exitfiHOME=/home/cybrary/Documents/OUTDIRECTORY=$4LOG=$HOME/LOGEXPECTED_RETURN="221 Goodbye."LIST_OF_FILES=list_of_filescd $DIRECTORYls -lrt $5* >$LIST_OF_FILEScat $LIST_OF_FILES|while read LINEdofilename=`echo $LINE|awk '{print $9}'`size=`echo $LINE|awk '{print $5}'`if [ "$filename" = "" ]; thenfilename=tempelif [ "$filename" = "_" ]; thenfilename=tempelseecho "Transfering $filename"sh $HOME/upload.sh $filename $1 $2 $3 $6 >$LOG/ftp_logRETURN=`fgrep "221 Goodbye." $LOG/ftp_log`if [ "$RETURN" = "${EXPECTED_RETURN}" ]thenmv $DIRECTORY/$filename $DIRECTORY/FTPED/$filenameelseecho "Unable to establish connection"fifidone

 Execute_FTP.sh: The main script that will carry out the functionality of FTP service.Parser.sh: This file holds the IP, the Username, the Password, the Source and the Filename.Upload.sh: The FTP Environment Commands.I hope these script files can help you. If you have some questions or you want to fix or upgrade these scripts, you can contact me.
