Any ideas? I am attempting to write a script that uses sed.

If done this way it fails

  • rmdec=“sed ‘s/…$//’”
  • i1xmr=$(echo “$i1p/$apiresponse*1000” |bc -l |$rmdec)

But if i do it this way it works

  • i1xmr=$(echo “$i1p/$apiresponse*1000” |bc -l | sed ‘s/…$//’)

    Yeah, my goal is to shorten that sed command to that variable. It seems like it would work, but nope. It throws errors

      It might be because it’s a single string, and might work if you store it or expand it as an array. I think it would in Zsh, anyway.

      But the response to use a function instead is probably wiser.

        Strings work fine, the problem is the (single) quotes:

        ~ $ foo="echo 'hello world'"
        ~ $ for x in $foo; do echo $x; done
        echo
        'hello
        world'
        ~ $ $foo
        'hello world'
        ~ $ eval "$foo"
        hello world
        

        The splitting is by whitespace, so the single quotes remain in the arguments. Using eval (and double quotes to preven splitting), it gets processed correctly. That said, don’t use eval; use functions or aliases instead.

        Yep, the function did the trick. My guess is it was being misread at execution as a variable and thats why it was breaking
