Shell commands: Shell commands refer to the commands that are executed in a shell or terminal to interact with an operating system. This skill is essential in assessing a candidate's knowledge and proficiency in working with command-line interfaces and executing various operations such as file manipulation, process management, and system configuration.
Shell Scripting: Shell scripting involves writing sequences of commands in a scripting language to automate tasks and perform complex operations. Assessing this skill is crucial as it demonstrates a candidate's ability to create efficient and reusable scripts that enhance productivity and streamline system administration.
File Handling: File handling encompasses the operations performed on files, such as creating, reading, writing, modifying, and deleting files. Evaluating this skill allows recruiters to gauge a candidate's understanding of file systems, their ability to manipulate files, and their knowledge of file permissions, file formats, and file system organization.
Memory Management: Memory management refers to the management of computer memory resources to optimize the utilization of memory for efficient execution of programs. Assessing this skill helps recruiters assess a candidate's understanding of memory allocation, deallocation, memory leaks, and the ability to optimize memory usage in shell scripts.
Concurrent execution: Concurrent execution pertains to the ability to overlap multiple tasks to improve overall system performance. Evaluating this skill is significant as it demonstrates a candidate's familiarity with concurrent programming, process synchronization, scheduling, and efficient utilization of system resources.
Troubleshooting: Troubleshooting involves identifying and resolving issues or problems that may arise during the execution of shell scripts or system operations. This skill is vital to assess as it indicates a candidate's ability to analyze and debug errors, perform system diagnosis, and apply effective troubleshooting techniques to ensure smooth execution and optimal performance.
