From "man tr" on the RS/6000: (/usr/usg/tr is a hard link to /usr/bin/tr on
the default setup shipped by IBM).
For compatibility with BSD, there are two tr commands. The BSD
version is in the /usr/ucb/tr file. The AIX version is in the
/usr/usg/tr file.
In the AIX version, abbreviations that can be used to introduce
ranges of characters or repeated characters are as follows:
[a-z] Stands for a string of characters whose ASCII codes run from
character a to character z, inclusive.
[a*num] Stands for the number of repetitions of a. The num vari-
able is considered to be in decimal unless the first digit of num
is 0; then it is considered to be in octal.
In the BSD version, the abbreviation that can be used to intro-
duce ranges of characters is:
a-z Stands for a string of characters whose ASCII codes run from
character a to character z, inclusive.
....
2. To translate lowercase characters to uppercase:
/usr/usg/tr '[a-z]' '[A-Z]' <textfile >newfile
or
/usr/ucb/tr a-z A-Z <textfile >newfile
