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/$apiresponse*1000” |bc -l | sed ‘s/…$//’)

    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.
