       tr - translate or delete characters

       tr [OPTION]... SET1 [SET2]

       Translate, squeeze, and/or delete characters from standard input, writ-
       ing to standard output.

       -c, -C, --complement
	      use the complement of 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

	      output version information and exit

       SETs  are  specified  as	 strings  of characters.  Most represent them-
       selves.	Interpreted sequences are:

       \NNN   character with octal value NNN (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

	      all characters from CHAR1 to CHAR2 in ascending order

	      in SET2, copies of CHAR until length of SET1

	      REPEAT copies of CHAR, REPEAT octal if starting with 0

	      all letters and digits

	      all letters

	      all horizontal whitespace

	      all control characters

	      all digits

	      all printable characters, not including space

	      all lower case letters

	      all printable characters, including space

	      all punctuation characters

	      all horizontal or vertical whitespace

	      all upper case letters

	      all hexadecimal digits

	      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.
