My script contains something like this:

ifc=$(ifconfig)

With this, the ifc variable contains the output of the command ifconfig but without newlines. So, when I print it with echo $ifc I get only one line.

How can I include the newlines of subcommands?

The correct way to print is

echo "$ifc"

  • see Word Splitting in bash(1), you need quoting to preserve the spaces, tabs, or newlines. – livibetter Apr 8 '13 at 14:30
