Hi,

I am facing issue while executing the command free -m, it says command not found, not all the times, but some times.

Using oracle linux 6.x

please suggest.

I would think that the PATH is not set correctly.

Confirm that the command free exists:

Code:

$ type free
free is /usr/bin/free
$ ls -l /usr/bin/free
-rwxr-xr-x 1 root root 18624 Mar  6  2015 /usr/bin/free

Next time the command is not found, check your path:

Code:

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

It should contain the location of free. In the example, free resides at /usr/bin.

Solutions: Fix the PATH, or run /usr/bin/free.

Would be nice to explain the two situations when it was found and missing.

The free command is part of the procps package. Is the procps package installed?

Type free --help to see the supported options and free -V to see the package info.

Check possible $PATH issues as explained by berndbausch.

We will suggest, as we have many times in the past TWELVE YEARS, that you provide details when asking a question, such as how you're running this command. Telling us it doesn't work "some times" gives us zero details.

As an administrator with that many years experience, and after having been told/asked so many times, you should be well aware of these things. Check some of your (numerous) other threads about such topics:
