Shell Removing Tabs/Spaces

Question

I\'ve used a grep command with sed and cut filters that basically turns my output to something similar to this

    this line 1


    this line 2


    another li         


        

Answer 1

I would do this, short and simple:

sed 's: ::g'

Add this at the end of your command, and all whitespace will go poof. For example try this command:

cat /proc/meminfo | sed 's: ::g'
