nicogaspa / xv6_head_tail_implementation Goto Github PK

The project consist in the implementation of the "head" and "tail" commands in a proper way, so that it may work on the XV6 operating system. The commands are written using the C language, with the system calls and function available on the basic version of XV6.

The commands both work with multiple options and multiple files, both in number of rows or number of bytes mode, and they work in automatic verbose mode when 2 or more files are specified. It is also possible to not specify the file, thus work with the standard input.

To understand how these commands work it's possible to use the option --help The possible arguments are: -n NUM to operate with number of lines -c NUM to operate with number of bytes -q quiet mode -v verbose mode --version --help

2 text files have been added in order to test the function, when removed, the MAKEFILE must be modified too.

NOT IMPLEMENTED: multiplier suffix, as in standard unix function -NUM option, since it works with -n NUM
