In this tutorial I will show you some useful awk uses.
Determine Line Number
This will find the line number of the text_to_find.
lineNumber=`awk '/TEXT_TO_FIND/{print NR}' /file/path/name.extension`
Split Text By Space
If you want to split a word by a space and then select the second one
val='test test2'
echo $val | awk '{ print $2 }'
Split Text By Comma
If you want to split a word by a space and then select the second one
val='test test2'
echo $val | awk -F, '{ print $2 }'
