POHow can I rewrite the terminal output of a program
text
Body
copied!<p>I'm running an application (CoronaSDK Simulator) from the terminal that puts an insanely long timestamp in front of every line of output.</p> <p>Is there a way to use something like sed to chop it off and instead output everything else as it comes in (i.e. without having to wait until the program ends)?</p> <p>I've tried a couple of things, but have had no luck so far...</p> <p>Here are some sample lines:</p> <pre><code>2013-02-14 12:39:49.028 Corona Simulator[40803:707] |timer created 2013-02-14 12:39:49.029 Corona Simulator[40803:707] __in deck.lua__ 2013-02-14 12:39:49.030 Corona Simulator[40803:707] storyboard.roomData.layout=A1 (room.lua) </code></pre> <p>Which I want to look like this:</p> <pre><code>|timer created __in deck.lua__ storyboard.roomData.layout=A1 (room.lua) </code></pre> <p>I have tried</p> <pre><code>coronasim ./ | sed 's/Corona Simulator//' </code></pre> <p>as a test, and </p> <pre><code>coronasim ./ | sed -e 's/^.* //' </code></pre> <p>as suggested below, and even</p> <pre><code>coronasim ./ > /dev/null </code></pre> <p>but nothing seems to change the output.</p> <p>The solutions was this:</p> <pre><code>coronasim ./ 2>&1 | sed -e 's/^.*] //' </code></pre> <p>as per choroba's suggestion below. Seems that the Corona SDK simulator sends output to stderr instead of stdout.</p> <p>And for anyone else interested, created a simple bash script that runs the program in the current director in the simulator, stripping out the timestamps:</p> <pre><code>/Applications/CoronaSDK/Corona\ Simulator.app/Contents/MacOS/Corona\ Simulat or ./ 2>&1 | sed -e 's/^.*] //' </code></pre>
