Top Forums Shell Programming and Scripting Different behavour with "tr" Post 302740075 by Corona688 on Wednesday 5th of December 2012 01:06:03 PM

Probably a character-set thing. The GNU utilities try to abide by your character set whenever possible, and UTF8 is increasingly standard, but the definition of :lower: and :upper: for UTF8 is going to be pretty big and complicated.

Other side-effects of this compliance are things like slow-performing grep -i.

Try LOCALE="C" tr ... and see if it works as expected.

Also, if you have a file in your directory named :, l, o, w, e, r, u, or p, [:lower:] and [:upper:] will actually glob those filenames, so put them in single quotes! '[:lower:]' '[:upper:]'
