Team, i need to know how to operate on value row wise after performing grep. I can operate column wise using $ but how to on row value?
my output is
cat file.txt | grep -o 'test1[^. ]*'
output:
test1-exam1-fail test1-exam3-fail test1-exam5-fail
Now with above output, i can use $1 to work on test1-exam1-fail but what should i use to work on test1-exam3-fail and also on exam5?
Using paste command we can convert rows to columns
cat file.txt | grep -o 'test1[^. ]*' | paste - - -
so use - equal to columns we want.
Then we can operate on these values are $x where x = 1,2,3
