bash - linux time 命令，为什么一定要指定绝对路径，

Question

比如 { time mysqldump > bak.sql; } 2> t.txt

mysqldump 一定要写绝对路径， 否则，bak.sql是空的。

Answer 1

It seems that your environment variables are wrong. Use env | grep PATH to check whether the paths corresponding to time mysqldump and other commands are in your PATH

Answer 2

Do you need an absolute path to run mysqldump normally?
