In this blog, I will record my learning process of Bash scripts. I won’t specifically spend a large amount of time learning Bash, for the fundamental usage of efficient tools is for improving efficiency, rather than anything else. Trapped into learning tools itself for too long is dangerous and meaningless.
My practice plan:
Try to familiarize command line in daily usage.
Follow Unix/Linux Philosophy
From comprehending others’ scripts or dotfiles to creating my own Bash scripts to implement automatic tasks

update my dlcpp.sh function:
This function is only used for deleting the complied binary files when I am coding with my cpp project and the homework of Data Structure. This may be dangerous if you use it casually in other directories.
# 检查是否找到任何文件 if [ -z "$binary_files" ]; then echo"No files detected" echo"Press Enter to quit." read whether_to_quit if [[ -z "$whether_to_quit" ]]; then return 0 fi fi
# 列出要删除的文件 echo"All files needs to be deleted" echo"$binary_files"
# 提示用户确认 echo"Are you sure to delete these files? (Danger sometimes!) [yes/anything else]" # 读取用户输入 read confirmation
# 根据用户输入进行处理 if [[ "$confirmation" == "yes" ]]; then echo"Deleting" echo"$binary_files" | xargs rm -f echo"Done" else echo"No files deleted" fi }
