• GNU Coreutils

Usage

Split files into pieces

$ becat split [<options>] <file>...

Available options:

    --dec, --decimal             Show dec representation of number
    --no-dec, --no-decimal       Don't show dec representation of number
    --hex, --hexadecimal         Show hex representation of number
    --no-hex, --no-hexadecimal   Don't show hex representation of number
    --oct, --octal               Show oct representation of number
    --no-oct, --no-octal         Don't show oct representation of number

Read / concatenate files

$ becat join [<options>] <file>...

Available options:

-o, --output <filename>          Output filename

-l, --length <length>            Range length
-r, --range <start>-<end>        Range
-q, --quiet                      Quiet mode
    --dec, --decimal             Show dec representation of number
    --no-dec, --no-decimal       Don't show dec representation of number
    --hex, --hexadecimal         Show hex representation of number
    --no-hex, --no-hexadecimal   Don't show hex representation of number
    --oct, --octal               Show oct representation of number
    --no-oct, --no-octal         Don't show oct representation of number
