1,建立文字檔(包含帳號密碼資訊)
$vim users.txta001:a001
a002:a002
a003:a003
:
修正版:(互動式自動產生帳號流水號)
#!/bin/bash#自動產生帳號，密碼與帳號一致
while [ -z "$filename" ]
do
echo ""
read -p "請輸入要建立的檔案名稱: " filename
if [ "${filename##*.}" != "txt" ]
then
echo "僅能接受txt文字檔格式"
unset filename
fi
done
if [ -f "$filename" ]
then
read -p "該檔案已存在，是否要刪除(default: no)? " ans
if [ "$ans" == "Y" ]||[ "$ans" == "y" ]
then
rm $filename
else
unset filename
while [ -z "$filename" ]
do
echo ""
read -p "另一個名稱: " filename
if [ "${filename##*.}" != "txt" ]
then
echo "僅能接受txt文字檔格式"
unset filename
fi
done
fi
fi
while [ -z "$num" ]
do
echo ""
read -p "請輸入要產生的帳號數量: " num
s=$(echo $num|tr -d "0-9")
if [ -n "$s" ]||[ "$num" -le "0" ]
then
echo "請輸入合法且大於零的數字"
unset num
fi
done
while [ -z "$name" ]
do
echo ""
read -p "請輸入要產生的帳號名稱: " name
n=$(echo $name|tr -d "a-z" |tr -d "A-Z")
if [ -n "$n" ]
then
echo ""
echo "帳號名稱不可使用特殊字元或數字"
unset name
fi
done
touch $filename
count=1
if [ "$num" -lt 10 ]
then
while [ "$count" -le "$num" ]
do
echo -e $name"0"$count:$name"0"$count >> $filename
count=$(($count+1))
done
else
while [ "$count" -lt 10 ]
do
echo -e $name"0"$count:$name"0"$count >> $filename
count=$(($count+1))
done
while [ "$count" -le "$num" ]
do
echo -e "$name$count:$name$count" >> $filename
count=$(($count+1))
done
fi
2.建立批次程式:
$vim makeuser.sh#!/bin/bash
#Author : Marcus Tsai 20100914
#檔案固定，判斷是否由root執行，判斷檔案是否存在
filename=/home/student/bin/users.txt[ "$USER" != "root" ] && echo "need root permision" && exit 1
[ ! -f "$filename" ] && echo "file not found" && exit 1
s=$(cat $filename)
for us in $s
do
uname="${us%%:*}"
passwd="${us##*:}"
useradd -m -s /bin/bash $uname
echo "$uname:$passwd" |chpasswd
done
exit 0
<1>程式修正版:
#修改成由使用者自帶檔案位置 #!/bin/bash
#Author : Marcus Tsai 20100914
#filename=/home/student/bin/users.txt
#判斷是否root執行，參數是否沒給或超過1個，判斷檔案是否存在
[ "$USER" != "root" ] && echo "need root permision" && exit 1
[ "$#" != "1" ] && echo "wrong parameter!!just one please. " && exit 1
[ ! -f "$1" ] && echo "file not found" && exit 1
s=$(cat $1)
for us in $s
do
uname="${us%%:*}"
passwd="${us##*:}"
useradd -m -s /bin/bash $uname
echo "$uname:$passwd" |chpasswd
done
exit 0
