how to pipe and parse output of a command

learnfast · 06-15-2005, 04:47 AM

if the output of a command is e.g. "HEIGHT=1 WIDTH=14 COLOR=red SIZE=23" how can "pipe and parse" so that I get this output in a file:
HEIGHT=1
WIDTH=14
COLOR=red
SIZE=23

something like:
thecommand | replace(" ","\n") > output.txt

thanks

simply

command > output_file

hereoutput will stored in output_file

command > output_file 2> error_file
Here, stdout goes to output_file while anything written to stderr goes to error_file.

That doesn't add the newlines though, which from the look of it is the key thing. Try:

command | tr " " "\n" > output.txt
