file 여러개 자동으로 복사하기... (맨날 새로 만들기 귀찮아..ㅠㅠ)

#!/bin/bash
if [ "$#" -ne 2 ]; then
    echo "usage: $0 [filename] [repeat count]"
    exit
fi

if [ -f "$1" ]; then
    echo "$1 file exists."
else
    echo "$1 No such file. will exit"
    exit
fi

fileName=$(echo $1 | cut -d"." -f1)
fileCount=0
modInterval=$(( $2 / 10 ))
until [ "$fileCount" -ge $2 ]; do
    fileCount=$(expr $fileCount + 1)
    modulo=$(( $fileCount % $modInterval ))
    if [ $modulo -eq 0 ]; then
        echo "current fileCount: $fileCount completed"
    fi
    cp -f $1 "$fileName$fileCount.mpg"
done

뭔가 주기적으로 반복할때
#!/bin/bash
while true
do
    TODAY=$(date)
    echo "$TODAY excute command 'rm -rf Session*' "
    rm -rf Session*
    sleep 1800
done
