As others said, != is a numeric comparison; it will compare the numeric value of the left and right operands. Since your strings don't have digits at the beginning, their numeric value will be 0. Taking the numeric value of strings such as yours will trigger a warning if you have warnings enabled (which you should!) to alert you to a possible error on your part.

ne is the equivalent operator for string comparisons. Similarly, the numeric operators ==, <, >, <=, >=, and <=> have string equivalents eq, lt, gt, le, ge, and cmp.

Your other problem is using a \ in a double-quoted string. It has a special meaning as an escape character there. Use \\ to get a literal single backslash.
