I have two variables as follows
SampleOutput=`some command giving output`
Status=`echo "$SampleOutput" | grep -qs "Active"`
echo $SampleOutput
echo $Status
Here $SampleOutput
has value as AgentEnable=Active bla bla bla
However, $Status
is coming as blank
I am not sure why $Status
is coming as blank when it should have value AgentEnable=Active
When using grep -q
you don't get any output from grep
. Only return status is available that you can get using:
grep -qs "Enable" <<< "$SampleOutput"
Status=$?
As per man grep
:
-q, --quiet, --silent
Quiet mode: suppress normal output. grep will only search a file until a match has been found, making searches potentially less expensive.
Note that if you are not using SampleOutput
anywhere else then you can directly use:
some command | grep -qs "Enable"
Status=$?
