# Auxiliary commands

There are a few nearly-standalone programs which have a little 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 instead they're delivered within the main Miller executable for convenience.

GENMD-RUN-COMMAND
mlr aux-list
GENMD-EOF

GENMD-RUN-COMMAND
mlr lecat --help
GENMD-EOF

GENMD-RUN-COMMAND
mlr termcvt --help
GENMD-EOF

GENMD-RUN-COMMAND
mlr hex --help
GENMD-EOF

GENMD-RUN-COMMAND
mlr unhex --help
GENMD-EOF

Examples:

GENMD-RUN-COMMAND
echo 'Hello, world!' | mlr lecat --mono
GENMD-EOF

GENMD-RUN-COMMAND
echo 'Hello, world!' | mlr termcvt --lf2crlf | mlr lecat --mono
GENMD-EOF

GENMD-RUN-COMMAND
mlr hex data/budget.csv
GENMD-EOF

GENMD-RUN-COMMAND
mlr hex -r data/budget.csv
GENMD-EOF

GENMD-RUN-COMMAND
mlr hex -r data/budget.csv | sed 's/20/2a/g' | mlr unhex
GENMD-EOF

Additionally, [`mlr help`](online-help.md), [`mlr repl`](repl.md), and [`mlr regtest`](https://github.com/johnkerl/miller/blob/main/test/README.md) are implemented here.
