JULIA(1)

NAME
julia - high-level, high-performance dynamic programming language for technical computing

SYNOPSIS
julia [option] [program] [args..]

DESCRIPTION
Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library. The library, largely written in Julia itself, also integrates mature, best-of-breed C and Fortran libraries for linear algebra, random number generation, signal processing, and string processing. In addition, the Julia developer community is contributing a number of external packages through Julia's built-in package manager at a rapid pace. Julia programs are organized around multiple dispatch; by defining functions and overloading them for different combinations of argument types, which can also be user-defined. For a more in-depth discussion of the rationale and advantages of Julia over other systems, please see the online manual: https://docs.julialang.org If a Julia source file is given as a program (optionally followed by
 arguments in args) Julia will execute the program and exit.

COMMAND-LINE OPTIONS

-v, --version
    Display version information

-h, --help
    Print help message

--project[=<dir>/@.]
    Set <dir> as the home project/environment. The default @. option will search through parent directories until a Project.toml or JuliaProject.toml file is found.

-J, --sysimage <file>
    Start up with the given system image file

--sysimage-native-code={yes|no}
    Use precompiled code from system image if available

-H, --home <dir>
    Set location of julia executable

--startup-file={yes|no}
    Load ~/.julia/config/startup.jl

--handle-signals={yes|no}
    Enable or disable Julia's default signal handlers

-e, --eval <expr>
    Evaluate <expr>

-E, --print <expr>
    Evaluate <expr> and display the result

-L, --load <file>
    Load <file> immediately on all processors

-t, --threads <n>
    Enable n threads

-p, --procs <n>
    Run n local processes

--machine-file <file>
    Run processes on hosts listed in <file>

-i  Interactive mode; REPL runs and isinteractive() is true

--banner={yes|no|auto}
    Enable or disable startup banner

--color={yes|no|auto}
    Enable or disable color text

--history-file={yes|no}
    Load or save history

--compile={yes|no|all|min}
    Enable or disable compiler, or request exhaustive or minimal compilation

-C, --cpu-target=<target>
    Limit usage of cpu features up to <target>

-O, --optimize
    Run time-intensive code optimizations

-O <n>, --optimize=<n>
    Set the optimization level to <n>

--min-optlevel=<n>
    Set the minimum optimization level to <n>, overriding per-module settings

-g  Enable generation of full debug info

-g <n>
    Set the level of debug info generation to <n>

--inline={yes|no}
    Control whether inlining is permitted (overrides functions declared as @inline)

--check-bounds={yes|no|auto}
    Emit bounds checks always, never, or respect @inbounds declarations

--math-mode={ieee|user}
    Always use IEEE semantics for math (ignoring declarations), or adhere to declarations in source code

--depwarn={yes|no|error}
    Enable or disable syntax and method deprecation warnings ('error' turns warnings into errors)

--warn-overwrite={yes|no}
    Enable or disable method overwrite warnings

--output-o <name>
    Generate an object file (including system image data)

--output-ji <name>
    Generate a system image data file (.ji)

--output-bc <name>
    Generate LLVM bitcode (.bc)

--output-incremental={yes|no}
    Generate an incremental output file (rather than complete)

--code-coverage={none|user|all}, --code-coverage
    Count executions of source lines (omitting setting is equivalent to 'user')

--track-allocation={none|user|all}, --track-allocation
    Count bytes allocated by each source line

FILES
~/.julia/config/startup.jl
    Per user startup file.
/etc/julia/startup.jl
    System-wide startup file.
