1 通用的makefile
编写一个makefile，可以将其所在目录下的所有独立 .c 文件编译生成同名可执行文件。
src = $(wildcard *.c) # 拿到所有*.c
target = $(patsubst %.c, %, $(src)) # 将src中所有%.c替换成%ALL:$(target)%:%.cgcc $< -o $@clean:-rm -rf $(target).PHONY:clean ALL2 git相关
git init
git add .
git commit -m "first commit"
git remote add origin 仓库地址
git push -u origin master
git push -f origin master # 强制git diff HEAD -- readme.txt
git reset HEAD readme.txtgit log
git log --pretty=onelinegit reset --hard HEAD^
git reset --hard 1094a # 指定版本git switch master3 linux下vim自动在c文件插入文件头
打开vim配置
vim ~/.vimrc 插入以下代码
set nu
autocmd BufNewFile *.cpp,*.[ch],*.sh,*.java exec ":call SetTitle()"
"""定义函数SetTitle，自动插入文件头
func SetTitle()
"如果文件类型为.sh文件
if &filetype == 'sh'
