Question

Whenever i write grep -v "0" in order to ignore the 0 number somehow
the number 10 is getting ignored as well.

Please help me use the grep -v “0” with ignoring 0 in the process and not ignoring 10

So, grep works on a line-by-line basis. If something in the line matches, it matches the line. Since you’ve said to invert the set of matches (-v), it doesn’t show anything containing a 0 in the line, which 10 contains.

If you just have line-by-line output like

0
1
2
3
4
<whatever>
10
11

and you just want to ignore anything that is solely ‘0’,

you can do something like

grep -v “^0$”

I created a file containing some numbers

cat numbers.txt 
0
1
5
10
11
12

then ran the grep.

grep -v "^0$" numbers.txt 
1
5
10
11
12

Is that what you want?
