From: "Decklin Foster" <fosterd@hartwick.edu> To: rc@hawkwind.utcs.toronto.edu Subject: flattening a command substitution Date: Fri, 7 Jul 2000 21:50:38 -0500 [thread overview] Message-ID: <20000707215038.A5353@c26469-a.clnvl1.ct.home.com> (raw) Is there a way to perform a command substitution and flatten it all at once? For example, say I want to work with a pwd that has spaces: ; pwd /home/decklin ; mkdir 'foo bar' ; cd 'foo bar' ; ls `{pwd} ls: /home/decklin/foo: No such file or directory ls: bar: No such file or directory [nonzero status 1] ; ls ``(){pwd} ls: /home/decklin/foo bar : No such file or directory [nonzero status 1] ; Now, there are two ways I can get it to work: use a newline as the ifs-value, or have a temporary variable: pwd=`{pwd} ls $^pwd Neither strike me as being very elegant. The first option doesn't generalize to commands with multi-line output, and having to waste a variable seems wrong. Does anyone have a better idea? -- There is no TRUTH. There is no REALITY. There is no CONSISTENCY. There are no ABSOLUTE STATEMENTS. I'm very probably wrong. -- BSD fortune(6)
