Как сделать автоматический ввод набора команд в скрипт?

#!/bin/bash -e
cd "$(dirname "$0")"

test -e compiled || mkdir compiled

if [[ $# -ne 0 ]]; then
	for sourcefile in "$@"
	do
		smxfile="`echo $sourcefile | sed -e 's/\.sp$/\.smx/'`"
		echo -e "\nCompiling $sourcefile..."
		./spcomp $sourcefile -ocompiled/$smxfile
		lftp user:pass@ip
		cd /addons/sourcemod/plugins && mput /home/sm/compiled/$smxfile
	done
else
	for sourcefile in *.sp
	do
		smxfile="`echo $sourcefile | sed -e 's/\.sp$/\.smx/'`"
		echo -e "\nCompiling $sourcefile ..."
		./spcomp $sourcefile -ocompiled/$smxfile
		lftp user:pass:pass@ip | cd /addons/sourcemod/plugins && mput /home/sm/compiled/$smxfile
	done
