I have the following script, script.sh:
我有以下脚本script.sh:
`echo $1 $2`
When I run script.sh hd file I get the error:
当我运行script.sh高清文件时,我收到错误:
script.sh[1]: hd: not found
But when I run hd file in the command line the command runs successfully. How come inside the bash script the command does not exist and outside the script it does exist?
但是当我在命令行中运行hd文件时,命令运行成功。如果命令不存在于bash脚本中,并且在脚本之外它确实存在?

i think u just need to modify
我想你只需要修改
echo '$1 $2'
and than run this might solve
而不是运行这可能会解决
yaah but the main role of that backticks is that it executes commands in backticks before main command
是啊但是反引号的主要作用是它在主命令之前在反引号中执行命令
