What? You have a pipeline with nothing before it, and then another pipeline with "ls" on the right hand side. But ls doesn't even read from stdin! This is not even syntactically valid: arc3:/tmp$ | echo | ls bash: syntax error near unexpected token `|' And it's not semantically valid either, because piping to ls is ludicrous: arc3:/tmp$ echo hello world | ls arc3:/tmp$ > > '>' will not work unless eval is used in execute.sh.

You are passing it as an argument to ls. ../execute.sh has *no* arguments whatsoever. > This really belongs to the new help-b...@gnu.org mailing list > * https://lists.gnu.org/mailman/listinfo/help-bash Agreed. Here, this is my best guess as to what he wants: http://mywiki.wooledge.org/BashFAQ/050 -- I'm trying to put a command in a variable, but the complex cases always fail! If that doesn't cover it, then post (on help-bash) an English description of the actual *goal* you are trying to achieve. If you feel you must post code, then at least make sure the code is DIRECTLY COPIED FROM YOUR TERMINAL, not made up on the spot with syntax errors in it.
