- mkdir command not found in bash script 2 answers
在bash脚本2答案中找不到mkdir命令
I'm trying to make a script to mount a disk when runned. The script is
我正在尝试制作一个脚本来运行时安装磁盘。脚本是
#!/bin/bash
PATH=$(python /home/pi/prova.py 2>1&)
sudo mount $PATH /media/Drive1
where path in our case is /dev/sda1 (checked using echo).
在我们的例子中路径是/ dev / sda1(使用echo检查)。
The error reported is ./script.sh: line3: sudo: command not found
报告的错误是./script.sh:line3:sudo:找不到命令
the script is added to /etc/sudoers using line
使用line将脚本添加到/ etc / sudoers
pi ALL=NOPASSWD: /home/pi/script.sh
The error is the same both adding and removing the sudo before mount command.
在mount命令之前添加和删除sudo的错误都是相同的。
Any idea ? Thanks in advance

Don't use all-upper-case variable names for regular shell variables. This avoids overwriting environment variables and shell builtins (such as PATH, used by the shell to determine where it looks for external commands) by mistake.
不要对常规shell变量使用全大写变量名。这样可以避免错误地覆盖环境变量和shell内置函数(例如,shell使用它来确定它查找外部命令的位置)。
Thus, a corrected implementation of this script may be:
因此,此脚本的更正实现可能是:
#!/bin/bash
path=$(python /home/pi/prova.py 2>1&)
sudo mount "$path" /media/Drive1
