Hi all
Im trying to learn the basics of bash and am struggling with some file manipulation. I am trying to run a script that once you have logged in allows you to change your password which is held (along with the corresponding username) in a different file called usernames. When i try to run my code the logon part runs fine, but the change of password is not stored. Any advice would be greatly appreciated.
Thanks
Code:
#!/bin/bash
# script to change a password
username ()
{
while :
do
echo "please enter a username"
read user
grep -iq "$user" usernames
a=$?
echo "please enter pin"
read pin
grep -i "^$user" usernames | grep -q "$pin$"
b=$?
if [ $a -eq 0 -a $b -eq 0 ]
then
echo "Welcome"
change1
break
else
echo "Please try again"
fi
done
}
change1 ()
{
echo "please enter a new password"
read npass
sed 's/$pin/$npass/' usernames
echo "here are your logon details"
sed -n '/^$user/p' usernames
return
}
username
The file I am using looks like this:
Code:
#!/bin/bash
Username Password

Ok, is there anyway of using a sed command to change the contents of a file, as I have found that whilst my sed command changes the value on the command screen but not in the file. Is it possible to alter the value in the file?
