Redirect output to a file in linux

Its’ been kind of a while since I blogged on Linux.Sometimes we might require the outputs generated by a command to be stored in a text file for future use..This entry is all about dealing that.

There are essentially two different ways of doing it,depending on your requirement

1. commandname > filename

sample: ls > output.txt

The file is created in the current working directory.Upon usage of ‘>’,the previous contents are erased,and the new contents are written.

2. Sometimes you’ll need the contents to be preserved,In such a case use ‘>>’

eg: ls >> anerudh.txt

In this case,the file is updated,and your previous contents are unaltered.
