 If the above installation method seems like too much work, then just download a compiled binary package from [release page](https://github.com/neurobin/shc/releases/latest) and copy the `shc` binary to `/usr/bin` and `shc.1` file to `/usr/share/man/man1`.

+## Usage
 
 ```
 shc [options]
 shc -f script.sh -o binary
 shc -U -f script.sh -o binary # Untraceable binary (prevent strace, ptrace etc..)

+## Testing
 
 1. `cd` to `test` directory: `cd test`
 1. Try: `shc -f test.bash -o test`, where <span class="light-quote">test.bash</span> is the bash source.
 2. output binary file will be test. If no output file is specified
 by the `-o` option, then it will create an executable with `.x` extension by default.

-# Known bugs:
-
-
-The one (and I hope the only) limitation using shc is the
-_SC_ARG_MAX system configuration parameter.
-
-It limits the maximum length of the arguments to the exec function,
-limiting the maximum length of the runnable script of shc.
