Dear GNU,

Not sure if this is bug. But I think first one is legal command that is logically similar to second which works

Thank you,

Raj.

#1-- Error
address@hidden ~]$ echo "Raj" | tr "[[:alpha:]]" "[[:lower:]]"
tr: misaligned [:upper:] and/or [:lower:] construct

#2--Ok

address@hidden ~]$ echo "Raj" | tr "[[:upper:]]" "[[:lower:]]"
raj
address@hidden ~]$

address@hidden ~]$ tr --version
