How to make a one liner that can implement the prompt script to run multiple times?
eg. the simplest one i can think of:

i have one user list, name it as userlist.txt with content as below:
mary:mary@mail.com
kent:kent@mail.com
judy:judy@mail.com
……

with a script that used to reset single user password, resetpwd.sh
#!/bin/bash

user=$1

read -p “reset user password (y/n)” yn

case $yn in
y|Y)
echo “plsresetlater” | passwd –stdin $user &> /dev/null;;
n|N)
echo “user password did not change”;;
esac

then run the one liner by piping all the username to the resetpwd.sh; see output:

reset user password (y/n) y #user mary
reset user password (y/n) n #user kent
user password did not change
reset user password (y/n) n #user judy
user password did not change
……

i have tried the awk; not working
awk -F “:” ‘{print $1}’ userlist.txt | while read users; do resetpwd.sh $users; done

IF THIS does work
#!/bin/sh

set to
#!/bin/bash

Assuming that your file.txt is as follows:
val1 val2 val3

Here is a shell script:

#!/bin/sh
while read line
do
# store field 1
F1=$(echo $line|cut -d” ” -f1)
# store field 2
F2=$(echo $line|cut -d” ” -f2)
# store field
F3=$(echo $line|cut -d” ” -f3)
echo $F1 ” ” $F2 ” ” $F3
done < file.txt

Var $F1 $F2 and $F3 stores the value. If you need more help try out shell scripting forum @ http://forum.cyberciti.biz/
