Filter unprintable characters from input stream.

Short and simple. Follow the original Unix philosophy of a program doing just one thing where both input and output are streamed and are therefore able to function well in a pipe sequence.

File locations adjustable in makefile.

• Binary executable (fescape) located in /usr/local/bin
• Manpage (fescape.1) located in /usr/local/share/man/man1
• API documentation located in project folder as fescape-apidoc.pdf and fescape-apidoc.html. Doc source files in docs folder.

• file : file(s) to display or stdin if none specified

• -r, --repeats : display a count for repeated characters instead of displaying the characters themselves
• -h, --help : display usage
• -n, --newline : filter newlines
• -o, --octal : display octal codes instead of default hex codes

main()

• Handle switches
• Handle arguments
• Handle actions

void usage(const char *program)

• Display help to user

fescape(FILE *input_stream, FILE *output_stream, bool repeats, bool octal)

• Performs the filter function.

• system-actions.{c,h}
• actions.{c,h}
