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

    You need cat because it reads stdin and prints it to stdout. echo does not read stdin, it prints its arguments.

      I have never used cat like that before. If you just ent cat abcd > file it says abcd doesnt exist but does create “file”. I know you can cat contents of a file into another file but why the <<-EOF > file works is a bit beyond me.
