I was trying to change the
IFS(Internal Field Separator) character to comma for a file processing, but to my surprise the
IFS was un-changed.
Here's the order of commands and output :
mtk4@mtk-laptop:~$ echo .$IFS. . . # A space mtk4@mtk-laptop:~$ IFS="," # No error was thrown, no message mtk4@mtk-laptop:~$ echo .$IFS. . . # Again echo'd it, but no change
Please let me know, what is wrong here?
