School 42 ft_ls project (simplified copy of ls Unix utility)

ft_ls

This School 42 project is the first project from Unix-systems branch. In this project main goal is to copy utility ls from Unix based systems. This version of ls works like ls -1, flag -1 outputs each file/directory in its own row.

Installation

Simply type make && make clean in directory with project to install this "demo" ls version. (make for compile together all files and make clean to delete all binary *.o files)

After installing you can easily use it by ./ft_ls command.

Flags that you can use with this ft_ls are: usage: ls [-ARSafglmrst1] [file ...] The meaning of flags is same as in original ls.

Examples

Print content of current directory including hidden files in list format and sort it by size:

> ./ft_ls -laS                                                                                                                                                                                                             [±master ●]
