How do I pass the find command to the bash script as a argument? – CentOS

This command is a command to find hidden files.

The command is well recognized when executed at terminal.

However, if you turn the command over to the argument in the bash script, it will be recognized as an invalid command.

If you write together to recognize special characters, the results will not be printed.

I want to execute the command by passing the find command to the argument value of the bash script.

What should I do?

<test.sh>

#!/bin/bash
if [ -n $1 ]
then
    echo $@
    command=`$@`
    echo $command
fi

    You can try using eval instead

    test.sh

    #!/bin/bash
if [ -n $1 ]
then
    echo $@
    command=$@
    eval $command
fi

    [ linux ]$ ./test.sh find /tmp/ -xdev -name ".*"
find /tmp/ -xdev -name ".*"
/tmp/.hidden2
/tmp/.hidden1

    Escape the * so it’s not evaluated by the shell

    ./test.sh find / -xdev -name '.*'
