 ### readline :
-- readline
+- **readline** : `char *readline (const char *prompt);` will read a line from the terminal and return it, using prompt as a prompt
-- rl_clear_history
+- **rl_clear_history** : ` ` 
-- rl_on_new_line
+- **rl_on_new_line** : ` ` 
-- rl_replace_line
+- **rl_replace_line** : ` ` 
-- rl_redisplay
+- **rl_redisplay** : ` ` 
-- add_history
+- **add_history** : ` ` 
 ### files :
-- access
+- **access** : `int access(const char *pathname, int mode);` checks whether the calling process can access the file pathname
-- open
+- **open** : `int open(const char *pathname, int flags, [mode_t mode]);` system call opens the file specified by pathname
-- read
+- **read** : `ssize_t read(int fd, void *buf, size_t count);` attempts to read up to count bytes from file descriptor fd into the buffer starting at buf
-- close
+- **close** : `int close(int fd);` closes a file descriptor, so that it no longer refers to any file and may be reused
-- dup
+- **dup** : `int dup(int oldfd);` creates a copy of the file descriptor oldfd, using the lowest-numbered unused file descriptor for the new descriptor
-- dup2
+- **dup2** : `int dup2(int oldfd, int newfd);` performs the same task as dup(), but instead of using the  lowest-numbered  unused  file descriptor, it uses the file descriptor number specified in newfd
-- pipe
+- **pipe** : `int pipe(int pipefd[2]);` creates a pipe, a unidirectional data channel that can be used for interprocess communication. The array pipefd is used to return two file descriptors referring to the ends of the pipe. pipefd[0] refers to the read end of the pipe. pipefd[1] refers to the write end of the pipe
-- stat : `int stat(const char *pathname, struct stat *statbuf);` returns information about a file, in the buffer pointed to by statbuf
+- **stat** : `int stat(const char *pathname, struct stat *statbuf);` returns information about a file, in the buffer pointed to by statbuf
-- lstat : `int fstat(int fd, struct stat *statbuf);` lstat() is  identical  to stat(), except that if pathname is a symbolic link, then it returns information about the link itself, not the file that it refers to
+- **lstat** : `int fstat(int fd, struct stat *statbuf);` lstat() is  identical  to stat(), except that if pathname is a symbolic link, then it returns information about the link itself, not the file that it refers to
-- fstat : `int lstat(const char *pathname, struct stat *statbuf);` fstat() is identical to stat(), except that the file about which information is to be retrieved is specified by the file descriptor fd
+- **fstat** : `int lstat(const char *pathname, struct stat *statbuf);` fstat() is identical to stat(), except that the file about which information is to be retrieved is specified by the file descriptor fd
-- unlink : `int unlink(const char *pathname);` unlink() deletes a name from the filesystem
+- **unlink** : `int unlink(const char *pathname);` unlink() deletes a name from the filesystem
 ### process :
-- fork
+- **fork** : ` ` 
-- wait
+- **wait** : ` ` 
-- waitpid
+- **waitpid** : ` `

-- sigaction
+- **sigaction** : ` ` 
-- kill
+- **kill** : ` ` 
 ### directories :
-- getcwd : `char *getcwd(char *buf, size_t size);` returns a null-terminated string containing an absolute pathname that is the current working directory of the calling process
+- **getcwd** : `char *getcwd(char *buf, size_t size);` returns a null-terminated string containing an absolute pathname that is the current working directory of the calling process
-- chdir : `int chdir(const char *path);` changes the current working directory of the calling process to the directory specified in path
+- **chdir** : `int chdir(const char *path);` changes the current working directory of the calling process to the directory specified in path
-- execve : `int execve(const char *filename, char *const argv[], char *const envp[]);` executes the program pointed to by filename
+- **execve** : `int execve(const char *filename, char *const argv[], char *const envp[]);` executes the program pointed to by filename
-- opendir : `DIR *opendir(const char *name);` opens a directory stream corresponding to the directory name, and returns a pointer to the directory stream
+- **opendir** : `DIR *opendir(const char *name);` opens a directory stream corresponding to the directory name, and returns a pointer to the directory stream
-- readdir : `struct dirent *readdir(DIR *dirp);` returns a pointer to a dirent structure representing the next directory entry in the directory stream pointed to by dirp
+- **readdir** : `struct dirent *readdir(DIR *dirp);` returns a pointer to a dirent structure representing the next directory entry in the directory stream pointed to by dirp
-- closedir : `int closedir(DIR *dirp);` closes the directory stream associated with dirp
+- **closedir** : `int closedir(DIR *dirp);` closes the directory stream associated with dirp
 ### errors :
-- strerror : `char *strerror(int errnum);` returns a pointer to a string that describes the error code passed in the argument errnum
+- **strerror** : `char *strerror(int errnum);` returns a pointer to a string that describes the error code passed in the argument errnum
-- perror : `void perror(const char *s);` produces a message on standard error describing the last error encountered during a call to a system or library function
+- **perror** : `void perror(const char *s);` produces a message on standard error describing the last error encountered during a call to a system or library function
