相對於第一次寫的shell編程，本次變動為：使用shell函數，使代碼更簡潔，使用trap捕捉信號，不許ctrl+c強制退出，其他無改進，代碼如下：
trap "echo Error!!" SIGINT SIGTERM
echo $2|grep "[[:punct:]]" &> /dev/null && echo "Sorry! Filename only accept input(A-z or 0-9)" && exit 1
FTB=${2:-demo}
MaxArr=`ls ./|grep $FTB|grep -v ${FTB}.sh|cut -d"." -f1|awk -F"${FTB}" '{print $NF}'|sort -n|tail -1`
MaxFile=$((MaxArr+1))
Max=`ls ./|grep ${FTB}'[0-9][0-9]*'.sh|tail -1`
Havesame=`ls ./|grep -v ${FTB}'[0-9][0-9]*'.sh|grep ${FTB}`
Have1=`ls ./|grep ${FTB}|wc -l`
Create(){
if [[ ! -f ./${FTB}.sh && -z $Max ]];then
`touch ./${FTB}.sh;chmod 700 ./${FTB}.sh`
# echo "Create File ${FTB}.sh Success"
echo -e '#!/bin/bash\n#Author: MOS\n'"#Date & Time: `date +%F/%T`\n#Version: 1.0.1\n#Description:\n#" > ./${FTB}.sh
Res=`echo "${PWD}/${FTB}.sh"`
elif [[ $Have1 = 1 && $Havesame = "${FTB}.sh" ]];then
`touch ./${FTB}${Have1}.sh;chmod 700 ./${FTB}${Have1}.sh`
# echo "Create File ${FTB}${Have1}.sh Success"
echo -e '#!/bin/bash\n#Author: MOS\n'"#Date & Time: `date +%F/%T`\n#Version: 1.0.1\n#Description:\n#" > ./${FTB}${Have1}.sh
Res=`echo "${PWD}/${FTB}${Have1}.sh"`
else
`touch ./${FTB}${MaxFile}.sh;chmod 700 ./${FTB}${MaxFile}.sh`
# echo "Create File ${FTB}${MaxFile}.sh Success"
echo -e '#!/bin/bash\n#Author: MOS\n'"#Date & Time: `date +%F/%T`\n#Version: 1.0.1\n#Description:\n#" > ./${FTB}${MaxFile}.sh
Res=`echo "${PWD}/${FTB}${MaxFile}.sh"`
fi
}
if [[ -z $1 || $1 == "-c" && -n $2 ]];then
Create
echo $Res
elif [[ $1 = "-d" ]];then
Create
vim +$ $Res
until bash -n $Res &> /dev/null ;do
read -p "Syntax error!Are you sure you want to exit now?(y|n): " Quit
if [[ $Quit == y ]];then
echo "Give up debug!!"
exit 1
fi
vim +$ $Res
done
elif [[ $1 = "-m" ]];then
Date=`date +%m-%d-%H:%M`
mkdir -m 700 ./tmp$Date;mv *.sh ./tmp$Date
fi
