Grep -v "Ready" without taking out "Not Ready"

Question

oc get serviceinstances | grep -v Ready

There are some results that are "Not Ready" but it would take them out as well because it looks for "Ready".

There are lots of different status names and "Ready" are the only ones I don't need.

For instance:

Ready
Not Ready
Error
Failed

I need "Not Ready", "Error", "Failed"

@Ostone0 `grep -i 'ready' test | grep -vi 'not ready'`, maybe? — Renaud Pacalet, Jan 03 '22 at 15:22

@Tom S Please show the output of `oc get serviceinstances`. Please do this in your question, not in comments, external links, images... — Renaud Pacalet, Jan 03 '22 at 15:23
I think you're asking *not* to see Ready, so use `grep -E "Not Ready|Error|Failed"` — jarmod, Jan 03 '22 at 15:33
There are about 10+ different statues, so what I was asking is not to see "Ready" but anything else, including "Not Ready" — Tom S, Jan 03 '22 at 15:35
@TomS Please, never show text with images. They are not searchable, not copy-paste-able and much heavier than needed. Moreover they affect accessibility negatively. Please copy-paste the text in your question and [format it properly](https://stackoverflow.com/help/formatting), instead. And do not forget to indicate what is the field separator in the output of `oc get serviceinstances`. Tabs? Spaces? — Renaud Pacalet, Jan 03 '22 at 15:43

Using your example data, you can try the -w flag in conjunction with -v flag

-w, --word-regexp
              Select  only  those  lines  containing  matches  that form whole
              words.  The test is that the matching substring must  either  be
              at  the  beginning  of  the  line,  or  preceded  by  a non-word
              constituent character.  Similarly, it must be either at the  end
              of  the  line  or  followed by a non-word constituent character.
              Word-constituent  characters  are  letters,  digits,   and   the
              underscore.  This option has no effect if -x is also specified.

$ grep -vw ' Ready' input_file

    Not Ready
    Error
    Failed

When the fields are separated by tabs, use

oc get serviceinstances | grep -E "\tReady\t"

If your grep supports -P (PCRE support) option, please try:

oc get serviceinstances | grep -v -P "(?<!Not )Ready"

The regex matches Ready unless it is preceded by Not , then the logic is negated by the -v option.
