1、编写脚本createuser.sh
#!/bin/sh
if [ $# -eq 0 ];then
echo "please input one parameter"
else
username=$1
if id -u $username >/dev/null 2>&1; then
echo "$username existed!"
else
useradd $username >/dev/null
echo `id -u $username`
fi
fi
2、编写生成脚本基本格式的脚本
cat ~/.vimrc
autocmd BufNewFile *.sh exec ":call SetTitle()"
func SetTitle()
if expand("%:e")=='sh'
call setline(1,"#!/bin/bash")
call setline(2,"#")
call setline(3,"#*************************************")
call setline(4,"#author: kau")
call setline(5,"#QQ: 1")
call setline(6,"#email: 1@qq.com")
call setline(7,"#version: 1.0")
call setline(8,"#date: ".strftime("%Y-%m-%d"))
call setline(9,"#description: studytest.")
call setline(10,"#*************************************")
endif
endfunc
3、查找/etc目录下大于1M且类型为普通文件的所有文件
find /etc/ -size +1M -type f
4、打包/etc/目录下面所有conf结尾的文件，压缩包名称为当天实际。并拷贝到/usr/local/src/ 目录备份
tar zcvf /usr/local/src/`date +"%Y%m%d"`.tar.gz $(find /etc -name "*.conf")
5、查找当前系统上没有属主或属组，且最近一个周内曾被访问过的文件或目录
find / -nouser -o -nogroup -a atime +7
6、查找/etc目录下至少有一类用户没有执行权限的文件
find /etc/ ! -perm 111 -type f
