Just a word of warning -- without double quotes around it, many spaces (or whatever IFS is set to) will be reduced to one space. Nulls always vanish in shells script output. Not that we need nulls for anything. But they are useful for some reason in binary files. – chris May 17 '10 at 14:24
i have an issue where the loop is not processing the last line of the file because it does not have a new-line character at the end. is there a way to fix this via "while read" or do i need to modifiy the input file? – ShoeLace Nov 29 '16 at 09:41
