Extract and place in variable
If i wanted to extract the number of collisions from the eth0 section of the ifconfig file and have the output placed in a variable how would i do this?
I can get the output displayed using:
/sbin/ifconfig eth0 | grep "collisions"
What command would i now use to place the output in a variable known as "Collisions"?
