If you do not remove the color code, in certain terminal, you will have below error:

$ for i in `ls`; do cp $i ${i}_bak; done

cp: cannot stat `\033[0m\033[01;32mwebinterface0\033[0m': No such file or directory

cp: cannot stat `\033[01;32mwebinterface1\033[0m': No such file or directory

So, before we copy the file, we should remove the color code from the original string:

for i in `ls`; do

    echo $i;

    j=`echo $i | sed -r "s/\x1B\[([0-9]{1,3}((;[0-9]{1,3})*)?)?[m|K]//g"`;

    echo $j;

    cp $j ${j}_bak; 

done

for j in TSEC OTC ESTT KWAY; do

    INF_NAME=INF_NAME_"$j"

    OUF_NAME=OUF_NAME_"$j"

    msg INFO "Input File Name: $KWAY_INF/${!INF_NAME}

    msg INFO "Output File    : $KWAY_OUF/${!OUF_NAME}

done

p_yyyymmdd='^(19|20)[0-9]{6}$'

if [[ ! "$yyyymmdd" =~ $p_yyyymmdd ]]; then 

        result="USAGE - yyyymmdd format"
