Help with simple IF statements
Hi im new to unix shell scripting but not new to codeing itself.

Anyways im making a auto .conf for an eggdropbot and need an If statment.

Code:
read -p 'Bot Nickname:' ecnick
echo Your Bots Nick Is $ecnick

What i want is for if nothing is entered it will do "read -p 'Bot Nickname:' ecnick" again untill the users enters a nickname and if a nickname is entered it will do "echo Your Bots Nick Is $ecnick".

Thanks
Gemster

Thanks ygemici, it works but ive had to change the coding a little and your script dont work now :/

Code:
read -p 'Bot Nickname:' ecnick
read -p 'Bot Username:' ecusername
read -p 'Bot realname:' ecrealname

So basically if the Nickname is not entered it wall ask for it again and again untill its entered then it will go the the username and so on.

Also I dont need the tries part of it Smilie

Thanks

"tries " is a little sample from me Smilie

lets try this Smilie

Code:
#!/bin/bash
while :;
 do
  read -p 'Bot Nickname:' ecnick
  if [ -z "$ecnick" ] ; then
    read -p 'Bot Nickname:' ecnick
  else
    echo Your Bots Nick Is $ecnick
    read -p 'Bot Username:' ecusername
    read -p 'Bot realname:' ecrealname
    break
  fi
 done

Ok havent tested it yet,

But from looking at it the first part is right for the Nickname but dont need the "echo Your Bots Nick Is $ecnick" and i need the Username and Realname to do the same as the Nickname ie: if they are not entered it will ask then the question again.

Thanks

Sorry for later reply (but i am sleeping methinks Smilie )

Code:
#!/bin/bash
zero () {
if [ -z $1 ] ; then
 if [ $2 == Nickname ] ; then
  read -p "Bot "$2":" ecnick
  zero "$ecnick" "Nickname"
 fi
  if [ $2 == "Username" ] ; then
   read -p "Bot "$2":" ecuname
   zero "$ecuname" "Username"
  fi
   if [ $2 == "Realname" ] ; then
    read -p "Bot "$2":" ecrname
  zero "$ecrname" "RealName"
  fi
   elif [ -n "$1" ] ; then
echo "Bot $2: $1"
fi
}
   read -p "Bot Nickname:" ecnick
   zero "$ecnick" "Nickname"
   read -p "Bot Username:" ecuname
   zero "$ecuname" "Username"
   read -p "Bot Realname:" ecrname
   zero "$ecrname" "Realname"

Thanks
