A response from a St. Louis colleague: ---------- Forwarded message ---------- From: Robert Citek <robert.citek@gmail.com> Date: Dec 17, 2006 7:42 PM Subject: Re: Fwd: Fwd: [DISCUSS] 10 Good Unix command line habits To: discuss@sluug.org Also, in "Use escape sequences to manage long input", there's no need to put a backslash after a pipe (|), logical or (||), or logical and (&&). So, this: ~ $ cd tmp/a/b/c || \

mkdir -p tmp/a/b/c && \ tar xvf -C tmp/a/b/c ~/archive.tar

can be re-written as this: ~ $ cd tmp/a/b/c ||

mkdir -p tmp/a/b/c && tar xvf -C tmp/a/b/c ~/archive.tar

Ed and Group,

Here's a note from one of our KC colleagues (to whom I forwarded this) pointing out an error on the page (which I noticed but didn't share).

Notes: In "Quote variables with caution", it says to use square brackets, and then goes on to give a correct example with curly braces. "Stop piping cats" only refers to piping to grep, but in reality there's almost never a good reason to pipe a single-file cat. The < operator provides a file on standard input. So "cat foo | wc -l" can become "wc -l < foo"
