    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:

    \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
    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.
