TOM T<?>T

MO T<?>
       Translate, squeeze, and/or delete characters from standard input,
       writing to standard output.  STRING1 and STRING2 specify arrays of
       characters ARRAY1 and ARRAY2 that control the action.

       -c, -C, --complement
              use the complement of ARRAY1

       -d, --delete
              delete characters in ARRAY1, do not translate

       -s, --squeeze-repeats
              replace each sequence of a repeated character that is listed in
              the last specified ARRAY, with a single occurrence of that
              character

       -t, --truncate-set1
              first truncate ARRAY1 to length of ARRAY2

       --help hi<?>n th<?> tr<?> giup nay r<?>i thoat

       --version

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

       \NNN   ky t<?> v<?>i gia tr<?> bat phan NNN (1 t<?>i 3 ch<?> s<?>)

       \\     s<?> cheo ngu<?>c

       Translation occurs if -d is not given and both STRING1 and STRING2
       appear.  -t is only significant when translating.  ARRAY2 is extended
       to length of ARRAY1 by repeating its last character as necessary.
       Excess characters of ARRAY2 are ignored.  Character classes expand in
       unspecified order; while translating, [:lower:] and [:upper:] may be
       used in pairs to specify case conversion.  Squeezing occurs after
       translation or deletion.

BUGS
       Full support is available only for safe single-byte locales, in which
       every possible input byte represents a single character.  The C locale
       is safe in GNU systems, so you can avoid this issue in the shell by
       running LC_ALL=C tr instead of plain tr.
