       tr - translate or delete characters

       tr [OPTION]... SET1 [SET2]

       Translate, squeeze, and/or delete characters from standard input, writing to standard out-

       -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

	      output version information and exit

       SETs  are  specified  as  strings  of characters.  Most represent themselves.  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 guar-
       anteed 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.
