Bugs and Bugs and that is what we live with
I was running a simple bash script and somehow the output was all wrong. I debugged the script and looked it multiple times with lot of printf but still could not find the issue..
Bug was: When assigning a variable, i was leaving a space between = and the string. Look at my series of bugs and please do not repeat my mistakes.
var= “do something” + ” and do something” # this is wrong not needed +
var= “do something””var2 shall do something” # this is wrong as var2 has to be $var2
var = “do something” # bash doesnt like u putting SPACE after = and it messes things up
var= $var2″ and some more $val3/$val4″ # to output another var use $ and no space needed
IMP: Bash doesnt take kindly when we put a space around”=” sign in variable assignment. I hate it and especially we who have grown out of .Net who is all too forgiving.
IMP2: When you use VAR = VALUE, the shell assumes that VAR must be the name of a command and tries to execute it.
