[SOLVED] Help in bash script

barakolshe · 07-08-2017, 06:02 PM

Hello, I am trying to write a basic script in bash, but unfortunately it has an error that i can't seem to understand.
This is the script:
#!/bin/sh

i = 2
line = $(echo "UoMYTrfrBFHyQXmg6gzctqAwOmw1IohZ $i" | nc localhost 30002 | head -3 | tail -1)
if ("$line" = "Wrong! Please enter the correct pincode. Try again.")
then
echo "$line" > password.txt
fi

The error is:
./dump.sh: 3: ./dump.sh: i: not found

Thanks in advance for the help

First, please use CODE tags around your scripts. Secondly, the error is telling you very plainly that the error is on line 3, and goes on to tell you that it's complaining about "i"...which is on line 3 where you have "i = 2". Check out the bash scripting tutorials about defining variables, and about declaring the proper variable types. Try removing the spaces between the = sign, like "i=2".

Maybe take the spaces out of i = 2.

Sorry, I was writing while TBone was posting.
