Reference: auxiliary commands

There are a few nearly-standalone programs which have nothing to do with the rest of Miller, do not participate in record streams, and do not deal with file formats. They might as well be little standalone executables but they’re delivered within the main Miller executable for convenience.

 mlr aux-list
 Available subcommands:
   aux-list
   hex
   lecat
   termcvt
   unhex
   help
   regtest
   repl
 For more information, please invoke mlr {subcommand} --help.

 mlr lecat --help
 Usage: mlr lecat [options] {zero or more file names}
 Simply echoes input, but flags CR characters in red and LF characters in green.
 If zero file names are supplied, standard input is read.
 Options:
 --mono: don't try to colorize the output
 -h or --help: print this message

 mlr termcvt --help
 Usage: mlr termcvt [option] {zero or more file names}
 Option (exactly one is required):
 --cr2crlf
 --lf2crlf
 --crlf2cr
 --crlf2lf
 --cr2lf
 --lf2cr
 -I in-place processing (default is to write to stdout)
 -h or --help: print this message
 Zero file names means read from standard input.
 Output is always to standard output; files are not written in-place.

 mlr hex --help
 Usage: mlr hex [options] {zero or more file names}
 Simple hex-dump.
 If zero file names are supplied, standard input is read.
 Options:
 -r: print only raw hex without leading offset indicators or trailing ASCII dump.
 -h or --help: print this message

 mlr unhex --help
 Usage: mlr unhex [option] {zero or more file names}
 Options:
 -h or --help: print this message
 Zero file names means read from standard input.
 Output is always to standard output; files are not written in-place.

Examples:

 echo 'Hello, world!' | mlr lecat --mono
 Hello, world![LF]

 echo 'Hello, world!' | mlr termcvt --lf2crlf | mlr lecat --mono
 Hello, world![CR][LF]
