This is a really simple bash question. I just wanted to know if there's any difference between IFS= and IFS=''.

CodePudding user response：

No, there is not. They both set IFS to an empty value.

CodePudding user response：

No, since the shell before executing, performs quote removal. This turns IFS='' (or IFS="") into IFS= anyway.

CodePudding user response：

It depends. Is the second string actually the string 4946 533d 2727, or is it 4946 533d 2701 27? Both strings will render as IFS='', but the second one does not assign the null string to IFS. If nothing nefarious is going on, then the string that you see as IFS='' is probably just the string 4946 533d 2727, but you need to be careful.
