Development of a Simple UNIX Shell (sshell) in C
Budget: $25 – $50 USD
150
We are seeking an experienced C programmer to develop a simple UNIX shell named sshell. This project aims to deepen understanding of UNIX system calls and shell operations. The sshell will handle command execution, built-in commands, output redirection, and piping. Key requirements include executing user-supplied commands with arguments, implementing core built-in commands (exit, cd, pwd), supporting output redirection and appending, as well as piping between multiple commands. The project should strictly adhere to coding standards, with the source code written in C and compiled with GCC using the GNU C Library. A detailed understanding of processes, file manipulation, and error management in a UNIX environment is essential.
Required Skills and Knowledge:
Proficient in C programming, particularly in a UNIX/Linux environment.
Strong understanding of system calls related to processes, files, and pipes.
Familiarity with the GNU C Library and GCC compiler.
Experience in implementing shell-like command-line interpreters.
Knowledge of shell scripting and command execution.
Ability to write clean, well-commented, and efficiently structured code.
Understanding of error handling and debugging techniques in C.
Familiarity with Makefiles and version control systems, like Git.
