Makefile execute script, run pass parameter change configuration

Recently, when compiling a colleague's program, I found that there are many options to make, so I wrote a script to simply fill in a few parameters before execution, and it's also a matter of temperature. Shell Programming

#!/bin/sh

read-p "Enter your mike:point Or ship    " var
mike= "${var:0:1}"
if [$mike = "P"-o $mike = "P"]
then
	mike= ' P '
else
	mike= ' S '
fi
Echo ' Mike is $mike '

read-p ' Enter your Led:tianmai Or Fuzhou Or Shanghai    "var
led=" ${var:0:1} "
if [$led =" T "-o $led =" T "]
then
	led= ' Tianmai ' 
 
  fi
If [$led = "F"-o $led = "F"]
then
	led= ' Fuzhou '
fi
if [$led = "s"-o $led = "s"]
n
	led= ' Shanghai '
fi
Echo ' LED is $led "


read-p" Enter your line:b1 Or other      "var
line=" ${ Var:0:1} "
if [$line =" B "-O $line =" B "]
then
	line= ' zhengzhou_b1 '

exit 0
