In bash script, how to assign output of a command to a variable while keeping tabs?
Hi, wondering if it's been asked before but didn't find matches from google. Basically I have this line:
Now somehow the '\t' from the echo output gets replaced with white space and then stored in $myvar.
It creates a problem for me later to use tab as delimiter to do cut on $myvar. Anyway to keep the tabs?
