autoheader command in Linux with Examples

Last Updated : 15 May, 2019

autoheader command in Linux is used to create a template file of C “#define” or any other template header for configure to use. If the user will give autoheader an argument, it reads the standard input instead of reading configure.ac and also writes the header file to the standard output. This command scans the configure.ac file and figures out which C preprocessor symbols it might have defined.

Syntax:

autoheader [OPTION]... [TEMPLATE-FILE]

Options:

-h, –help: Display the help message and then exits.
```
autoheader -h or autoheader --help

-V, –version: Shows the version number and then exits.
```
