You can chain Bash commands using operators like `&&` for sequential execution, `||` for fallback execution, and `|` to pipe output between commands. This allows you to build complex command sequences for efficient terminal operations.

Text processing with grep, sed, and awk works by parsing input streams to search, edit, and extract data patterns. Grep filters lines, sed performs stream editing, and awk handles complex data manipulation and columnar extraction.

The best way to find modified files and count lines in Linux is by combining the `find` command with `wc`. You can locate files modified within a specific timeframe and pipe the results to `wc` to count the total lines of code.

Yes, you can use shell scripting for process management and file operations on macOS, as well as Linux. The terminal commands for finding files, checking disk usage, and managing processes are compatible with both operating systems.

Shell scripts often fail when lacking proper error handling best practices. Implementing robust error handling ensures your script safely manages failures during command chaining, file operations, and process management tasks.
