Sometimes it is necessary to find solutions.
Today's example involves two linux commands:
watch and cat
Here is a simple method by creating a script that returns an output:
while [ 1 ]; do cat /proc/meminfo; date; echo; sleep 1; done
Make this script executable and name it: meminfo
Output is then processed by the command:
$ watch -d ./meminfo
