[Bash] execute string as command

Hi,

I am trying to execute a string as command.

Code:

txt="echo \"abc\""
`$txt`

result

Code:

./test.sh: line 2: "abc": command not found

What am I doing wrong?

Thanks.

Michael

I don't totally understand what you are trying to do, but if you need to send a command into a string there are couple of tricks:

Code:

$(command)

or

Code:

foo=`code`

` == backtick (found under the tilde, ~, key)

P.S. If this isn't correct, just post back with more specifics, and I'll try again.

Thanks for your info. I found what I need is eval.
