NAME
     tr - translate or delete characters

SYNOPSIS
     tr [OPTION]... SET1 [SET2]

DESCRIPTION
     Translate, squeeze, and/or delete characters  from  standard
     input, writing to standard output.

     -c, -C, --complement
          first complement SET1

     -d, --delete
          delete characters in SET1, do not translate

     -s, --squeeze-repeats
          replace each input sequence  of  a  repeated  character
          that is listed in SET1 with a single occurrence of that
          character

     -t, --truncate-set1
          first truncate SET1 to length of SET2

     --help
          display this help and exit

     --version
          output version information and exit

     SETs are specified as strings of characters.  Most represent
     themselves.  Interpreted sequences are:

     \N character with octal value N (1 to 3 octal digits)

     \\   backslash

     \a   audible BEL

     \b   backspace

     \f   form feed

     \n   new line

     \r   return

     \t   horizontal tab

     \v   vertical tab

     CHAR1-CHAR2

          all characters from CHAR1 to CHAR2 in ascending order

     [CHAR*]
          in SET2, copies of CHAR until length of SET1

     [CHAR*REPEAT]
          REPEAT copies of CHAR, REPEAT octal if starting with 0

     [:alnum:]
          all letters and digits

     [:alpha:]
          all letters

     [:blank:]
          all horizontal whitespace

     [:cntrl:]
          all control characters

     [:digit:]
          all digits

     [:graph:]
          all printable characters, not including space

     [:lower:]
          all lower case letters

     [:print:]
          all printable characters, including space

     [:punct:]
          all punctuation characters

     [:space:]
          all horizontal or vertical whitespace

     [:upper:]
          all upper case letters

     [:xdigit:]
          all hexadecimal digits

     [=CHAR=]
          all characters which are equivalent to CHAR

     Translation occurs if -d is not given and both SET1 and SET2
     appear.   -t  may  be  used  only when translating.  SET2 is
     extended to length of SET1 by repeating its  last  character
     as  necessary.  Excess characters of SET2 are ignored.  Only
     [:lower:]  and  [:upper:]  are  guaranteed  to   expand   in

     ascending  order;  used  in SET2 while translating, they may
     only be used in pairs to specify case conversion.   -s  uses
     SET1  if  not  translating nor deleting; else squeezing uses
     SET2 and occurs after translation or deletion.
