Is 8GB RAM enough for a MacBook?
Whether 8GBRAM is enough depends on the usage scenario. ① Daily office and study (document processing, web browsing, video conferencing) are basically sufficient; ② Programming and development and design work depend on the tool, front-end development may be tight, and back-end development and virtual machine operation are recommended 16GB or more; ③ 8GB is not recommended for video editing and running virtual machines, and it is recommended to directly choose 16GB or higher. Apple MacBook memory cannot be upgraded later, and it must be decided based on long-term use when purchasing.

What does set -e do in a shell script?
In shell scripts, the purpose of set-e is to make the script stop running immediately when any command execution fails (returns to a non-zero status code). By default, the Bash script continues to execute subsequent commands, even if a command has failed, which can cause errors to accumulate or produce unexpected results. After using set-e, the script will terminate at the first failed command. For example, the script will stop after executing the false command, and subsequent commands will not run. However, set-e is not completely reliable, with some exceptions: 1. The command in the if condition will not trigger the exit; 2. The command followed by ||true will not cause the script to exit; 3. The exit will only be triggered if the last command in the pipeline command fails. To enhance script robustness, it can be combined
