I cannot reproduce this problem on Debian Jessie 8 using grep 2.20 from the Debian distribution. Here is my test case. rwp@rainy:~$ echo ONE | GREP_OPTIONS= grep one rwp@rainy:~$ echo ONE | GREP_OPTIONS=--ignore-case grep one ONE rwp@rainy:~$ echo ONE | env -i GREP_OPTIONS=--ignore-case grep one ONE rwp@rainy:~$ grep --version grep (GNU grep) 2.20 Works for me. Perhaps you have some incompatible LC_COLLATE and LC_CTYPE variables mixing? Bob
